# Install #

Rclone is a Go program and comes as a single binary file.

## Quickstart ##

  * [Download](https://rclone.org/downloads/) the relevant binary.
  * Unpack and the `rclone` binary.
  * Run `rclone config` to setup. See [rclone config docs](https://rclone.org/docs/) for more details.

See below for some expanded Linux / macOS instructions.

See the [Usage section](https://rclone.org/docs/) of the docs for how to use rclone, or
run `rclone -h`.

## Linux installation from precompiled binary ##

Fetch and unpack

    curl -O https://downloads.rclone.org/rclone-current-linux-amd64.zip
    unzip rclone-current-linux-amd64.zip
    cd rclone-*-linux-amd64

Copy binary file

    sudo cp rclone /usr/bin/
    sudo chown root:root /usr/bin/rclone
    sudo chmod 755 /usr/bin/rclone
    
Install manpage

    sudo mkdir -p /usr/local/share/man/man1
    sudo cp rclone.1 /usr/local/share/man/man1/
    sudo mandb 

Run `rclone config` to setup. See [rclone config docs](https://rclone.org/docs/) for more details.

    rclone config

## macOS installation from precompiled binary ##

Download the latest version of rclone.

    cd && curl -O https://downloads.rclone.org/rclone-current-osx-amd64.zip

Unzip the download and cd to the extracted folder.

    unzip -a rclone-current-osx-amd64.zip && cd rclone-*-osx-amd64

Move rclone to your $PATH. You will be prompted for your password.

    sudo mkdir -p /usr/local/bin
    sudo mv rclone /usr/local/bin/

(the `mkdir` command is safe to run, even if the directory already exists).

Remove the leftover files.

    cd .. && rm -rf rclone-*-osx-amd64 rclone-current-osx-amd64.zip

Run `rclone config` to setup. See [rclone config docs](https://rclone.org/docs/) for more details.

    rclone config

## Install from source ##

Make sure you have at least [Go](https://golang.org/) 1.6 installed.
Make sure your `GOPATH` is set, then:

    go get -u -v github.com/ncw/rclone

and this will build the binary in `$GOPATH/bin`.  If you have built
rclone before then you will want to update its dependencies first with
this

    go get -u -v github.com/ncw/rclone/...

## Installation with Ansible ##

This can be done with [Stefan Weichinger's ansible
role](https://github.com/stefangweichinger/ansible-rclone).

Instructions

  1. `git clone https://github.com/stefangweichinger/ansible-rclone.git` into your local roles-directory
  2. add the role to the hosts you want rclone installed to:
    
```
    - hosts: rclone-hosts
      roles:
          - rclone
```

Configure
---------

First, you'll need to configure rclone.  As the object storage systems
have quite complicated authentication these are kept in a config file.
(See the `--config` entry for how to find the config file and choose
its location.)

The easiest way to make the config is to run rclone with the config
option:

    rclone config

Usage
-----

Rclone syncs a directory tree from one storage system to another.

Its syntax is like this

    Syntax: [options] subcommand <parameters> <parameters...>

Source and destination paths are specified by the name you gave the
storage system in the config file then the sub path, eg
"drive:myfolder" to look at "myfolder" in Google drive.

You can define as many storage paths as you like in the config file.

Subcommands
-----------

rclone uses a system of subcommands.  For example

    rclone ls remote:path # lists a re
    rclone copy /local/path remote:path # copies /local/path to the remote
    rclone sync /local/path remote:path # syncs /local/path to the remote

## rclone config

Enter an interactive configuration session.

### Synopsis


`rclone config`
 enters an interactive configuration sessions where you can setup
new remotes and manage existing ones. You may also set or remove a password to
protect your configuration.

Additional functions:

  * `rclone config edit` – same as above
  * `rclone config file` – show path of configuration file in use
  * `rclone config show` – print (decrypted) config file


```
rclone config [function] [flags]
```

### Options

```
  -h, --help   help for config
```

## rclone copy

Copy files from source to dest, skipping already copied

### Synopsis



Copy the source to the destination.  Doesn't transfer
unchanged files, testing by size and modification time or
MD5SUM.  Doesn't delete files from the destination.

Note that it is always the contents of the directory that is synced,
not the directory so when source:path is a directory, it's the
contents of source:path that are copied, not the directory name and
contents.

If dest:path doesn't exist, it is created and the source:path contents
go there.

For example

    rclone copy source:sourcepath dest:destpath

Let's say there are two files in sourcepath

    sourcepath/one.txt
    sourcepath/two.txt

This copies them to

    destpath/one.txt
    destpath/two.txt

Not to

    destpath/sourcepath/one.txt
    destpath/sourcepath/two.txt

If you are familiar with `rsync`, rclone always works as if you had
written a trailing / - meaning "copy the contents of this directory".
This applies to all commands and whether you are talking about the
source or destination.

See the `--no-traverse` option for controlling whether rclone lists
the destination directory or not.


```
rclone copy source:path dest:path [flags]
```

### Options

```
  -h, --help   help for copy
```

## rclone sync

Make source and dest identical, modifying destination only.

### Synopsis



Sync the source to the destination, changing the destination
only.  Doesn't transfer unchanged files, testing by size and
modification time or MD5SUM.  Destination is updated to match
source, including deleting files if necessary.

**Important**: Since this can cause data loss, test first with the
`--dry-run` flag to see exactly what would be copied and deleted.

Note that files in the destination won't be deleted if there were any
errors at any point.

It is always the contents of the directory that is synced, not the
directory so when source:path is a directory, it's the contents of
source:path that are copied, not the directory name and contents.  See
extended explanation in the `copy` command above if unsure.

If dest:path doesn't exist, it is created and the source:path contents
go there.


```
rclone sync source:path dest:path [flags]
```

### Options

```
  -h, --help   help for sync
```

## rclone move

Move files from source to dest.

### Synopsis



Moves the contents of the source directory to the destination
directory. Rclone will error if the source and destination overlap and
the remote does not support a server side directory move operation.

If no filters are in use and if possible this will server side move
`source:path` into `dest:path`. After this `source:path` will no
longer longer exist.

Otherwise for each file in `source:path` selected by the filters (if
any) this will move it into `dest:path`.  If possible a server side
move will be used, otherwise it will copy it (server side if possible)
into `dest:path` then delete the original (if no errors on copy) in
`source:path`.

**Important**: Since this can cause data loss, test first with the
--dry-run flag.


```
rclone move source:path dest:path [flags]
```

### Options

```
  -h, --help   help for move
```

## rclone delete

Remove the contents of path.

### Synopsis



Remove the contents of path.  Unlike `purge` it obeys include/exclude
filters so can be used to selectively delete files.

Eg delete all files bigger than 100MBytes

Check what would be deleted first (use either)

    rclone --min-size 100M lsl remote:path
    rclone --dry-run --min-size 100M delete remote:path

Then delete

    rclone --min-size 100M delete remote:path

That reads "delete everything with a minimum size of 100 MB", hence
delete all files bigger than 100MBytes.


```
rclone delete remote:path [flags]
```

### Options

```
  -h, --help   help for delete
```

## rclone purge

Remove the path and all of its contents.

### Synopsis



Remove the path and all of its contents.  Note that this does not obey
include/exclude filters - everything will be removed.  Use `delete` if
you want to selectively delete files.


```
rclone purge remote:path [flags]
```

### Options

```
  -h, --help   help for purge
```

## rclone mkdir

Make the path if it doesn't already exist.

### Synopsis


Make the path if it doesn't already exist.

```
rclone mkdir remote:path [flags]
```

### Options

```
  -h, --help   help for mkdir
```

## rclone rmdir

Remove the path if empty.

### Synopsis



Remove the path.  Note that you can't remove a path with
objects in it, use purge for that.

```
rclone rmdir remote:path [flags]
```

### Options

```
  -h, --help   help for rmdir
```

## rclone check

Checks the files in the source and destination match.

### Synopsis



Checks the files in the source and destination match.  It compares
sizes and hashes (MD5 or SHA1) and logs a report of files which don't
match.  It doesn't alter the source or destination.

If you supply the --size-only flag, it will only compare the sizes not
the hashes as well.  Use this for a quick check.

If you supply the --download flag, it will download the data from
both remotes and check them against each other on the fly.  This can
be useful for remotes that don't support hashes or if you really want
to check all the data.


```
rclone check source:path dest:path [flags]
```

### Options

```
      --download   Check by downloading rather than with hash.
  -h, --help       help for check
```

## rclone ls

List all the objects in the path with size and path.

### Synopsis


List all the objects in the path with size and path.

```
rclone ls remote:path [flags]
```

### Options

```
  -h, --help   help for ls
```

## rclone lsd

List all directories/containers/buckets in the path.

### Synopsis


List all directories/containers/buckets in the path.

```
rclone lsd remote:path [flags]
```

### Options

```
  -h, --help   help for lsd
```

## rclone lsl

List all the objects path with modification time, size and path.

### Synopsis


List all the objects path with modification time, size and path.

```
rclone lsl remote:path [flags]
```

### Options

```
  -h, --help   help for lsl
```

## rclone md5sum

Produces an md5sum file for all the objects in the path.

### Synopsis



Produces an md5sum file for all the objects in the path.  This
is in the same format as the standard md5sum tool produces.


```
rclone md5sum remote:path [flags]
```

### Options

```
  -h, --help   help for md5sum
```

## rclone sha1sum

Produces an sha1sum file for all the objects in the path.

### Synopsis



Produces an sha1sum file for all the objects in the path.  This
is in the same format as the standard sha1sum tool produces.


```
rclone sha1sum remote:path [flags]
```

### Options

```
  -h, --help   help for sha1sum
```

## rclone size

```

## rclone dedupe

Interactively find duplicate files delete/rename them.

### Synopsis



By default `dedupe` interactively finds duplicate files and offers to
delete all but one or rename them to be different. Only useful with
Google Drive which can have duplicate file names.

In the first pass it will merge directories with the same name.  It
will do this iteratively until all the identical directories have been
merged.

The `dedupe` command will delete all but one of any identical (same
md5sum) files it finds without confirmation.  This means that for most
duplicated files the `dedupe` command will not be interactive.  You
can use `--dry-run` to see what would happen without doing anything.

Here is an example run.

Before - with duplicates

    $ rclone lsl drive:dupes
      6048320 2016-03-05 16:23:16.798000000 one.txt
      6048320 2016-03-05 16:23:11.775000000 one.txt
       564374 2016-03-05 16:23:06.731000000 one.txt
      6048320 2016-03-05 16:18:26.092000000 one.txt
      6048320 2016-03-05 16:22:46.185000000 two.txt
      1744073 2016-03-05 16:22:38.104000000 two.txt
       564374 2016-03-05 16:22:52.118000000 two.txt

Now the `dedupe` session

    $ rclone dedupe drive:dupes
    2016/03/05 16:24:37 Google drive root 'dupes': Looking for duplicates using interactive mode.
    one.txt: Found 4 duplicates - deleting identical copies

    s/k/r> r
    two-1.txt: renamed from: two.txt
    two-2.txt: renamed from: two.txt
    two-3.txt: renamed from: two.txt

The result being

    $ rclone lsl drive:dupes
      6048320 2016-03-05 16:23:16.798000000 one.txt
       564374 2016-03-05 16:22:52.118000000 two-1.txt
      6048320 2016-03-05 16:22:46.185000000 two-2.txt
      1744073 2016-03-05 16:22:38.104000000 two-3.txt

Dedupe can be run non interactively using the `--dedupe-mode` flag or by using an extra parameter with the same value

  * `--dedupe-mode interactive` - interactive as above.
  * `--dedupe-mode skip` - removes identical files then skips anything left.
  * `--dedupe-mode first` - removes identical files then keeps the first one.
  * `--dedupe-mode newest` - removes identical files then keeps the newest one.
  * `--dedupe-mode oldest` - removes identical files then keeps the oldest one.
  * `--dedupe-mode rename` - removes identical files then renames the rest to be different.

For example to rename all the identically named photos in your Google Photos directory, do

    rclone dedupe --dedupe-mode rename "drive:Google Photos"

Or

    rclone dedupe rename "drive:Google Photos"


```
rclone dedupe [mode] remote:path [flags]
```

### Options

```
      --dedupe-mode string   Dedupe mode interactive|skip|first|newest|oldest|rename. (default "interactive")
  -h, --help                 help for dedupe
```

## rclone authorize

Remote authorization.

### Synopsis



Remote authorization. Used to authorize a remote or headless
rclone from a machine with a browser - use as instructed by
rclone config.

```
rclone authorize [flags]
```

### Options

```
  -h, --help   help for authorize
```

## rclone cat

Concatenates any files and sends them to stdout.

### Synopsis



rclone cat sends any files to standard output.

You can use it like this to output a single file

    rclone cat remote:path/to/file

Or like this to output any file in dir or subdirectories.

    rclone cat remote:path/to/dir

Or like this to output any .txt files in dir or subdirectories.

    rclone --include "*.txt" cat remote:path/to/dir

Use the --head flag to print characters only at the start, --tail for
the end and --offset and --count to print a section in the middle.
Note that if offset is negative it will count from the end, so
--offset -1 --count 1 is equivalent to --tail 1.


```
rclone cat remote:path [flags]
```

### Options

```
      --count int    Only print N characters. (default -1)
      --discard      Discard the output instead of printing.
      --head int     Only print the first N characters.
  -h, --help         help for cat
      --offset int   Start printing at offset N (or from end if -ve).
      --tail int     Only print the last N characters.
```

## rclone copyto

Copy files from source to dest, skipping already copied

### Synopsis



If source:path is a file or directory then it copies it to a file or
directory named dest:path.

This can be used to upload single files to other than their current
name.  If the source is a directory then it acts exactly like the copy
command.

So

    rclone copyto src dst

where src and dst are rclone paths, either remote:path or
/path/to/local or C:\windows\path\if\on\windows.

This will:

    if src is file
        copy it to dst, overwriting an existing file if it exists
    if src is directory
        copy it to dst, overwriting existing files if they exist
        see copy command for full details

This doesn't transfer unchanged files, testing by size and
modification time or MD5SUM.  It doesn't delete files from the
destination.


```
rclone copyto source:path dest:path [flags]
```

### Options

```
  -h, --help   help for copyto
```

## rclone cryptcheck

Cryptcheck checks the integrity of a crypted remote.

### Synopsis



rclone cryptcheck checks a remote against a crypted remote.  This is
the equivalent of running rclone check, but able to check the
checksums of the crypted remote.

For it to work the underlying remote of the cryptedremote must support
some kind of checksum.

It works by reading the nonce from each file on the cryptedremote: and
using that to encrypt each file on the remote:.  It then checks the
checksum of the underlying file on the cryptedremote: against the
checksum of the file it has just encrypted.

Use it like this

    rclone cryptcheck /path/to/files encryptedremote:path

You can use it like this also, but that will involve downloading all
the files in remote:path.

    rclone cryptcheck remote:path encryptedremote:path

After it has run it will log the status of the encryptedremote:.


```
rclone cryptcheck remote:path cryptedremote:path [flags]
```

### Options

```
  -h, --help   help for cryptcheck
```

## rclone cryptdecode

Cryptdecode returns unencrypted file names.

### Synopsis



rclone cryptdecode returns unencrypted file names when provided with
a list of encrypted file names. List limit is 10 items.

use it like this

	rclone cryptdecode encryptedremote: encryptedfilename1 encryptedfilename2


```
rclone cryptdecode encryptedremote: encryptedfilename [flags]
```

### Options

```
  -h, --help   help for cryptdecode
```

## rclone dbhashsum

Produces a Dropbbox hash file for all the objects in the path.

### Synopsis



Produces a Dropbox hash file for all the objects in the path.  The
hashes are calculated according to [Dropbox content hash
rules](https://www.dropbox.com/developers/reference/content-hash).
The output is in the same format as md5sum and sha1sum.


```
rclone dbhashsum remote:path [flags]
```

### Options

```
  -h, --help   help for dbhashsum
```

## rclone listremotes

List all the remotes in the config file.

### Synopsis



rclone listremotes lists all the available remotes from the config file.

When uses with the -l flag it lists the types too.


```
rclone listremotes [flags]
```

### Options

```
  -h, --help   help for listremotes
  -l, --long   Show the type as well as names.
```

## rclone lsjson

List directories and objects in the path in JSON format.

### Synopsis


List directories and objects in the path in JSON format.

The output is an array of Items, where each Item looks like this

   {
      "Hashes" : {
         "SHA-1" : "f572d396fae9206628714fb2ce00f72e94f2258f",
         "MD5" : "b1946ac92492d2347c6235b4d2611184",
         "DropboxHash" : "ecb65bb98f9d905b70458986c39fcbad7715e5f2fcc3b1f07767d7c83e2438cc"
      },
      "IsDir" : false,
      "ModTime" : "2017-05-31T16:15:57.034468261+01:00",
      "Name" : "file.txt",
      "Path" : "full/path/goes/here/file.txt",
      "Size" : 6
   }

If --hash is not specified the the Hashes property won't be emitted.

If --no-modtime is specified then ModTime will be blank.

The time is in RFC3339 format with nanosecond precision.

The whole output can be processed as a JSON blob, or alternatively it
can be processed line by line as each item is written one to a line.


```
rclone lsjson remote:path [flags]
```

### Options

```
      --hash         Include hashes in the output (may take longer).
  -h, --help         help for lsjson
      --no-modtime   Don't read the modification time (can speed things up).
  -R, --recursive    Recurse into the listing.
```

## rclone mount

Mount the remote as a mountpoint. **EXPERIMENTAL**

### Synopsis



rclone mount allows Linux, FreeBSD, macOS and Windows to
mount any of Rclone's cloud storage systems as a file system with
FUSE.

This is **EXPERIMENTAL** - use with care.

First set up your remote using `rclone config`.  Check it works with `rclone ls` etc.

Start the mount like this

    rclone mount remote:path/to/files /path/to/local/mount

Or on Windows like this where X: is an unused drive letter

    rclone mount remote:path/to/files X:

When the program ends, either via Ctrl+C or receiving a SIGINT or SIGTERM signal,
the mount is automatically stopped.

The umount operation can fail, for example when the mountpoint is busy.
When that happens, it is the user's responsibility to stop the mount manually with

    # Linux
    fusermount -u /path/to/local/mount
    # OS X
    umount /path/to/local/mount

### Installing on Windows ###

To run rclone mount on Windows, you will need to
download and install [WinFsp](http://www.secfs.net/winfsp/).

WinFsp is an [open source](https://github.com/billziss-gh/winfsp)
Windows File System Proxy which makes it easy to write user space file
systems for Windows.  It provides a FUSE emulation layer which rclone
uses combination with
[cgofuse](https://github.com/billziss-gh/cgofuse).  Both of these
packages are by Bill Zissimopoulos who was very helpful during the
implementation of rclone mount for Windows.

#### Windows caveats ####

Note that drives created as Administrator are not visible by other
accounts (including the account that was elevated as
Administrator). So if you start a Windows drive from an Administrative
Command Prompt and then try to access the same drive from Explorer
(which does not run as Administrator), you will not be able to see the
new drive.

The easiest way around this is to start the drive from a normal
command prompt. It is also possible to start a drive from the SYSTEM
account (using [the WinFsp.Launcher
infrastructure](https://github.com/billziss-gh/winfsp/wiki/WinFsp-Service-Architecture))
which creates drives accessible for everyone on the system.

### Limitations ###

This can only write files seqentially, it can only seek when reading.
This means that many applications won't work with their files on an
rclone mount.

The bucket based remotes (eg Swift, S3, Google Compute Storage, B2,
Hubic) won't work from the root - you will need to specify a bucket,
or a path within the bucket.  So `swift:` won't work whereas
`swift:bucket` will as will `swift:bucket/path`.
None of these support the concept of directories, so empty
directories will have a tendency to disappear once they fall out of
the directory cache.

Only supported on Linux, FreeBSD, OS X and Windows at the moment.

### rclone mount vs rclone sync/copy ##

File systems expect things to be 100% reliable, whereas cloud storage
systems are a long way from 100% reliable. The rclone sync/copy
commands cope with this with lots of retries.  However rclone mount
can't use retries in the same way without making local copies of the
uploads.  This might happen in the future, but for the moment rclone
mount won't do that, so will be less reliable than the rclone command.

### Filters ###

Note that all the rclone filters can be used to select a subset of the
files to be visible in the mount.

### Directory Cache ###

Using the `--dir-cache-time` flag, you can set how long a
directory should be considered up to date and not refreshed from the
backend. Changes made locally in the mount may appear immediately or
invalidate the cache. However, changes done on the remote will only
be picked up once the cache expires.

Alternatively, you can send a `SIGHUP` signal to rclone for
it to flush all directory caches, regardless of how old they are.
Assuming only one rclone instance is running, you can reset the cache
like this:

    kill -SIGHUP $(pidof rclone)


```
rclone mount remote:path /path/to/mountpoint [flags]
```

### Options

```
      --allow-non-empty           Allow mounting over a non-empty directory.
      --allow-other               Allow access to other users.
      --allow-root                Allow access to root user.
      --debug-fuse                Debug the FUSE internals - needs -v.
      --default-permissions       Makes kernel enforce access control based on the file mode.
      --dir-cache-time duration   Time to cache directory entries for. (default 5m0s)
      --fuse-flag stringArray     Flags or arguments to be passed direct to libfuse/WinFsp. Repeat if required.
      --gid uint32                Override the gid field set by the filesystem. (default 502)
  -h, --help                      help for mount
      --max-read-ahead int        The number of bytes that can be prefetched for sequential reads. (default 128k)
      --no-checksum               Don't compare checksums on up/download.
      --no-modtime                Don't read/write the modification time (can speed things up).
      --no-seek                   Don't allow seeking in files.
  -o, --option stringArray        Option for libfuse/WinFsp. Repeat if required.

      --uid uint32                Override the uid field set by the filesystem. (default 502)
      --umask int                 Override the permission bits set by the filesystem.
      --write-back-cache          Makes kernel buffer writes before sending them to rclone. Without this, writethrough caching is used.
```

## rclone moveto

Move file or directory from source to dest.

### Synopsis



If source:path is a file or directory then it moves it to a file or
directory named dest:path.

This can be used to rename files or upload single files to other than
their existing name.  If the source is a directory then it acts exacty
like the move command.

So

    rclone moveto src dst

where src and dst are rclone paths, either remote:path or
/path/to/local or C:\windows\path\if\on\windows.

This will:

    if src is file
        move it to dst, overwriting an existing file if it exists
    if src is directory
        move it to dst, overwriting existing files if they exist
        see move command for full details

This doesn't transfer unchanged files, testing by size and
modification time or MD5SUM.  src will be deleted on successful
transfer.

**Important**: Since this can cause data loss, test first with the
--dry-run flag.


```
rclone moveto source:path dest:path [flags]
```

### Options

```
  -h, --help   help for moveto
```

## rclone ncdu

Explore a remote with a text based user interface.

### Synopsis



This displays a text based user interface allowing the navigation of a
remote. It is most useful for answering the question - "What is using
all my disk space?".

To make the user interface it first scans the entire remote given and
builds an in memory representation.  rclone ncdu can be used during
this scanning phase and you will see it building up the directory
structure as it goes along.

Here are the keys - press '?' to toggle the help on and off

     ↑,↓ or k,j to Move
     →,l to enter
     ←,h to return
     c toggle counts
     g toggle graph
     n,s,C sort by name,size,count
     ? to toggle help on and off
     q/ESC/c-C to quit

This an homage to the [ncdu tool](https://dev.yorhel.nl/ncdu) but for
rclone remotes.  It is missing lots of features at the moment, most
importantly deleting files, but is useful as it stands.


```
rclone ncdu remote:path [flags]
```

### Options

```
  -h, --help   help for ncdu
```

## rclone obscure

Obscure password for use in the rclone.conf

### Synopsis


Obscure password for use in the rclone.conf

```
rclone obscure password [flags]
```

### Options

```
  -h, --help   help for obscure
```

## rclone rcat

Copies standard input to file on remote.

### Synopsis



rclone rcat reads from standard input (stdin) and copies it to a
single remote file.

    echo "hello world" | rclone rcat remote:path/to/file
    ffmpeg - | rclone rcat --checksum remote:path/to/file

If the remote file already exists, it will be overwritten.

rcat will try to upload small files in a single request, which is
usually more efficient than the streaming/chunked upload endpoints,
which use multiple requests. Exact behaviour depends on the remote.
What is considered a small file may be set through
`--streaming-upload-cutoff`. Uploading only starts after
the cutoff is reached or if the file ends before that. The data
must fit into RAM. The cutoff needs to be small enough to adhere
the limits of your remote, please see there. Generally speaking,
setting this cutoff too high will decrease your performance.

Note that the upload can also not be retried because the data is
not kept around until the upload succeeds. If you need to transfer
a lot of data, you're better off caching locally and then
`rclone move` it to the destination.

```
rclone rcat remote:path [flags]
```

### Options

```
  -h, --help   help for rcat
```

## rclone rmdirs

Remove empty directories under the path.

### Synopsis


This removes any empty directories (or directories that only contain
empty directories) under the path that it finds, including the path if
it has nothing in.

This is useful for tidying up remotes that rclone has left a lot of
empty directories in.



```
rclone rmdirs remote:path [flags]
```

### Options

```
  -h, --help   help for rmdirs
```

## rclone tree

List the contents of the remote in a tree like fashion.

### Synopsis



rclone tree lists the contents of a remote in a similar way to the
unix tree command.

For example

    $ rclone tree remote:path
    /
    ├── file1
    ├── file2
    ├── file3
    └── subdir
        ├── file4
        └── file5
    
    1 directories, 5 files

You can use any of the filtering options with the tree command (eg
--include and --exclude).  You can also use --fast-list.

The tree command has many options for controlling the listing which
are compatible with the tree command.  Note that not all of them have
short options as they conflict with rclone's short options.


```
rclone tree remote:path [flags]
```

### Options

```
  -a, --all             All files are listed (list . files too).
  -C, --color           Turn colorization on always.
  -d, --dirs-only       List directories only.
      --dirsfirst       List directories before files (-U disables).
      --full-path       Print the full path prefix for each file.
  -h, --help            help for tree
      --human           Print the size in a more human readable way.
      --level int       Descend only level directories deep.
  -D, --modtime         Print the date of last modification.
  -i, --noindent        Don't print indentation lines.
      --noreport        Turn off file/directory count at end of tree listing.
  -o, --output string   Output to file instead of stdout.
  -p, --protections     Print the protections for each file.
  -Q, --quote           Quote filenames with double quotes.
  -s, --size            Print the size in bytes of each file.
      --sort string     Select sort: name,version,size,mtime,ctime.
      --sort-ctime      Sort files by last status change time.
  -t, --sort-modtime    Sort files by last modification time.
  -r, --sort-reverse    Reverse the order of the sort.
  -U, --unsorted        Leave files unsorted.
      --version         Sort files alphanumerically by version.
```


Copying single files
--------------------

rclone normally syncs or copies directories.  However, if the source
remote points to a file, rclone will just copy that file.  The
destination remote must point to a directory - rclone will give the
error `Failed to create file system for "remote:file": is a file not a
directory` if it isn't.

For example, suppose you have a remote with a file in called
`test.jpg`, then you could copy just that file like this

    rclone copy remote:test.jpg /tmp/download

The file `test.jpg` will be placed inside `/tmp/download`.

This is equivalent to specifying

    rclone copy --no-traverse --files-from /tmp/files remote: /tmp/download

Where `/tmp/files` contains the single line

    test.jpg

It is recommended to use `copy` when copying individual files, not `sync`.
They have pretty much the same effect but `copy` will use a lot less
memory.

Quoting and the shell
---------------------

When you are typing commands to your computer you are using something
called the command line shell.  This interprets various characters in
an OS specific way.

Here are some gotchas which may help users unfamiliar with the shell rules

### Linux / OSX ###

If your names have spaces or shell metacharacters (eg `*`, `?`, `$`,
`'`, `"` etc) then you must quote them.  Use single quotes `'` by default.

    rclone copy 'Important files?' remote:backup

If you want to send a `'` you will need to use `"`, eg

    rclone copy "O'Reilly Reviews" remote:backup

The rules for quoting metacharacters are complicated and if you want
the full details you'll have to consult the manual page for your
shell.

### Windows ###

If your names have spaces in you need to put them in `"`, eg

    rclone copy "E:\folder name\folder name\folder name" remote:backup

If you are using the root directory on its own then don't quote it
(see [#464](https://github.com/ncw/rclone/issues/464) for why), eg

    rclone copy E:\ remote:backup

Copying files or directories with `:` in the names
--------------------------------------------------

rclone uses `:` to mark a remote name.  This is, however, a valid
filename component in non-Windows OSes.  The remote name parser will
only search for a `:` up to the first `/` so if you need to act on a
file or directory like this then use the full path starting with a
`/`, or use `./` as a current directory prefix.

So to sync a directory called `sync:me` to a remote called `remote:` use

    rclone sync ./sync:me remote:path

or

    rclone sync /full/path/to/sync:me remote:path

Server Side Copy
----------------

Most remotes (but not all - see [the
overview](/overview/#optional-features)) support server side copy.

This means if you want to copy one folder to another then rclone won't
download all the files and re-upload them; it will instruct the server
to copy them in place.

Eg

    rclone copy s3:oldbucket s3:newbucket

Will copy the contents of `oldbucket` to `newbucket` without
downloading and re-uploading.

Remotes which don't support server side copy **will** download and
re-upload in this case.

Server side copies are used with `sync` and `copy` and will be
identified in the log when using the `-v` flag.  The `move` command
may also use them if remote doesn't support server side move directly.
This is done by issuing a server side copy then a delete which is much
quicker than a download and re-upload.

Server side copies will only be attempted if the remote names are the
same.

This can be used when scripting to make aged backups efficiently, eg

    rclone sync remote:current-backup remote:previous-backup
    rclone sync /path/to/files remote:current-backup

Options
-------

Rclone has a number of options to control its behaviour.

Options which use TIME use the go time parser.  A duration string is a
possibly signed sequence of decimal numbers, each with optional
fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m". Valid
time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".

Options which use SIZE use kByte by default.  However, a suffix of `b`
for bytes, `k` for kBytes, `M` for MBytes and `G` for GBytes may be
used.  These are the binary units, eg 1, 2\*\*10, 2\*\*20, 2\*\*30
respectively.

### --backup-dir=DIR ###

When using `sync`, `copy` or `move` any files which would have been
overwritten or deleted are moved in their original hierarchy into this
directory.

If `--suffix` is set, then the moved files will have the suffix added
to them.  If there is a file with the same path (after the suffix has
been added) in DIR, then it will be overwritten.

The remote in use must support server side move or copy and you must
use the same remote as the destination of the sync.  The backup
directory must not overlap the destination directory.

For example

    rclone sync /path/to/local remote:current --backup-dir remote:old

will sync `/path/to/local` to `remote:current`, but for any files
which would have been updated or deleted will be stored in
`remote:old`.

If running rclone from a script you might want to use today's date as
the directory name passed to `--backup-dir` to store the old files, or
you might want to pass `--suffix` with today's date.

### --bind string ###

Local address to bind to for outgoing connections.  This can be an
IPv4 address (1.2.3.4), an IPv6 address (1234::789A) or host name.  If
the host name doesn't resolve or resoves to more than one IP address
it will give an error.

### --bwlimit=BANDWIDTH_SPEC ###

This option controls the bandwidth limit. Limits can be specified
in two ways: As a single limit, or as a timetable.

Single limits last for the duration of the session. To use a single limit,
specify the desired bandwidth in kBytes/s, or use a suffix b|k|M|G.  The
default is `0` which means to not limit bandwidth.

For example, to limit bandwidth usage to 10 MBytes/s use `--bwlimit 10M`

It is also possible to specify a "timetable" of limits, which will cause
certain limits to be applied at certain times. To specify a timetable, format your
entries as "HH:MM,BANDWIDTH HH:MM,BANDWIDTH...".

An example of a typical timetable to avoid link saturation during daytime
working hours could be:

`--bwlimit "08:00,512 12:00,10M 13:00,512 18:00,30M 23:00,off"`

In this example, the transfer bandwidth will be set to 512kBytes/sec at 8am.
At noon, it will raise to 10Mbytes/s, and drop back to 512kBytes/sec at 1pm.
At 6pm, the bandwidth limit will be set to 30MBytes/s, and at 11pm it will be
completely disabled (full speed). Anything between 11pm and 8am will remain
unlimited.

Bandwidth limits only apply to the data transfer. They don't apply to the
bandwidth of the directory listings etc.

Note that the units are Bytes/s, not Bits/s.  Typically connections are
measured in Bits/s - to convert divide by 8.  For example, let's say
you have a 10 Mbit/s connection and you wish rclone to use half of it
- 5 Mbit/s.  This is 5/8 = 0.625MByte/s so you would use a `--bwlimit
0.625M` parameter for rclone.

On Unix systems (Linux, MacOS, …) the bandwidth limiter can be toggled by
sending a `SIGUSR2` signal to rclone. This allows to remove the limitations
of a long running rclone transfer and to restore it back to the value specified
with `--bwlimit` quickly when needed. Assuming there is only one rclone instance
running, you can toggle the limiter like this:

    kill -SIGUSR2 $(pidof rclone)

### --buffer-size=SIZE ###

Use this sized buffer to speed up file transfers.  Each `--transfer`
will use this much memory for buffering.

Set to 0 to disable the buffering for the minimum memory usage.

### --checkers=N ###

The number of checkers to run in parallel.  Checkers do the equality
checking of files during a sync.  For some storage systems (eg S3,
Swift, Dropbox) this can take a significant amount of time so they are
run in parallel.

The default is to run 8 checkers in parallel.

### -c, --checksum ###

Normally rclone will look at modification time and size of files to
see if they are equal.  If you set this flag then rclone will check
the file hash and size to determine if files are equal.

This is useful when the remote doesn't support setting modified time
and a more accurate sync is desired than just checking the file size.

This is very useful when transferring between remotes which store the
same hash type on the object, eg Drive and Swift. For details of which
remotes support which hash type see the table in the [overview
section](https://rclone.org/overview/).

Eg `rclone --checksum sync s3:/bucket swift:/bucket` would run much
quicker than without the `--checksum` flag.

When using this flag, rclone won't update mtimes of remote files if
they are incorrect as it would normally.

### --config=CONFIG_FILE ###

Specify the location of the rclone config file.

Normally the config file is in your home directory as a file called
`.config/rclone/rclone.conf` (or `.rclone.conf` if created with an
older version). If `$XDG_CONFIG_HOME` is set it will be at
`$XDG_CONFIG_HOME/rclone/rclone.conf`

If you run `rclone -h` and look at the help for the `--config` option
you will see where the default location is for you.

Use this flag to override the config location, eg `rclone
--config=".myconfig" .config`.

### --contimeout=TIME ###

Set the connection timeout. This should be in go time format which
looks like `5s` for 5 seconds, `10m` for 10 minutes, or `3h30m`.

The connection timeout is the amount of time rclone will wait for a
connection to go through to a remote object storage system.  It is
`1m` by default.

### --dedupe-mode MODE ###

Mode to run dedupe command in.  One of `interactive`, `skip`, `first`, `newest`, `oldest`, `rename`.  The default is `interactive`.  See the dedupe command for more information as to what these options mean.

### --disable FEATURE,FEATURE,... ###

This disables a comma separated list of optional features. For example
to disable server side move and server side copy use:

    --disable move,copy

The features can be put in in any case.

To see a list of which features can be disabled use:

    --disable help

See the overview [features](/overview/#features) and
[optional features](/overview/#optional-features) to get an idea of
which feature does what.

This flag can be useful for debugging and in exceptional circumstances
(eg Google Drive limiting the total volume of Server Side Copies to
100GB/day).

### -n, --dry-run ###

Do a trial run with no permanent changes.  Use this to see what rclone
would do without actually doing it.  Useful when setting up the `sync`
command which deletes files in the destination.

### --ignore-checksum ###

Normally rclone will check that the checksums of transferred files
match, and give an error "corrupted on transfer" if they don't.

You can use this option to skip that check.  You should only use it if
you have had the "corrupted on transfer" error message and you are
sure you might want to transfer potentially corrupted data.

### --ignore-existing ###

Using this option will make rclone unconditionally skip all files
that exist on the destination, no matter the content of these files.

While this isn't a generally recommended option, it can be useful
in cases where your files change due to encryption. However, it cannot
correct partial transfers in case a transfer was interrupted.

### --ignore-size ###

Normally rclone will look at modification time and size of files to
see if they are equal.  If you set this flag then rclone will check
only the modification time.  If `--checksum` is set then it only
checks the checksum.

It will also cause rclone to skip verifying the sizes are the same
after transfer.

This can be useful for transferring files to and from OneDrive which
occasionally misreports the size of image files (see
[#399](https://github.com/ncw/rclone/issues/399) for more info).

### -I, --ignore-times ###

Using this option will cause rclone to unconditionally upload all
files regardless of the state of files on the destination.

Normally rclone would skip any files that have the same
modification time and are the same size (or have the same checksum if
using `--checksum`).

### --immutable ###

Treat source and destination files as immutable and disallow
modification.

With this option set, files will be created and deleted as requested,
but existing files will never be updated.  If an existing file does
not match between the source and destination, rclone will give the error
`Source and destination exist but do not match: immutable file modified`.

Note that only commands which transfer files (e.g. `sync`, `copy`,
`move`) are affected by this behavior, and only modification is
disallowed.  Files may still be deleted explicitly (e.g. `delete`,
`purge`) or implicitly (e.g. `sync`, `move`).  Use `copy --immutable`
if it is desired to avoid deletion as well as modification.

This can be useful as an additional layer of protection for immutable
or append-only data sets (notably backup archives), where modification
implies corruption and should not be propagated.

### --log-file=FILE ###

Log all of rclone's output to FILE.  This is not active by default.
This can be useful for tracking down problems with syncs in
combination with the `-v` flag.  See the [Logging section](#logging)
for more info.

### --log-level LEVEL ###

This sets the log level for rclone.  The default log level is `INFO`.

`DEBUG` is equivalent to `-vv`. It outputs lots of debug info - useful
for bug reports and really finding out what rclone is doing.

`INFO` is equivalent to `-v`. It outputs information about each transfer
and prints stats once a minute by default.

`NOTICE` is the default log level if no logging flags are supplied. It
outputs very little when things are working normally. It outputs
warnings and significant events.

`ERROR` is equivalent to `-q`. It only outputs error messages.

### --low-level-retries NUMBER ###

This controls the number of low level retries rclone does.

A low level retry is used to retry a failing operation - typically one
HTTP request.  This might be uploading a chunk of a big file for
example.  You will see low level retries in the log with the `-v`
flag.

This shouldn't need to be changed from the default in normal operations.
However, if you get a lot of low level retries you may wish
to reduce the value so rclone moves on to a high level retry (see the
`--retries` flag) quicker.

Disable low level retries with `--low-level-retries 1`.

### --max-depth=N ###

This modifies the recursion depth for all the commands except purge.

So if you do `rclone --max-depth 1 ls remote:path` you will see only
the files in the top level directory.  Using `--max-depth 2` means you
will see all the files in first two directory levels and so on.

For historical reasons the `lsd` command defaults to using a
`--max-depth` of 1 - you can override this with the command line flag.

You can use this command to disable recursion (with `--max-depth 1`).

Note that if you use this with `sync` and `--delete-excluded` the
files not recursed through are considered excluded and will be deleted
on the destination.  Test first with `--dry-run` if you are not sure
what will happen.

### --modify-window=TIME ###

When checking whether a file has been modified, this is the maximum
allowed time difference that a file can have and still be considered
equivalent.

The default is `1ns` unless this is overridden by a remote.  For
example OS X only stores modification times to the nearest second so
if you are reading and writing to an OS X filing system this will be
`1s` by default.

This command line flag allows you to override that computed default.

### --no-gzip-encoding ###

Don't set `Accept-Encoding: gzip`.  This means that rclone won't ask
the server for compressed files automatically. Useful if you've set
the server to return files with `Content-Encoding: gzip` but you
uploaded compressed files.

There is no need to set this in normal operation, and doing so will
decrease the network transfer efficiency of rclone.

### --no-update-modtime ###

When using this flag, rclone won't update modification times of remote
files if they are incorrect as it would normally.

This can be used if the remote is being synced with another tool also
(eg the Google Drive client).

### -q, --quiet ###

Normally rclone outputs stats and a completion message.  If you set
this flag it will make as little output as possible.

### --retries int ###

Retry the entire sync if it fails this many times it fails (default 3).

Some remotes can be unreliable and a few retries help pick up the
files which didn't get transferred because of errors.

Disable retries with `--retries 1`.

### --size-only ###

Normally rclone will look at modification time and size of files to
see if they are equal.  If you set this flag then rclone will check
only the size.

This can be useful transferring files from Dropbox which have been
modified by the desktop sync client which doesn't set checksums of
modification times in the same way as rclone.

### --stats=TIME ###

Commands which transfer data (`sync`, `copy`, `copyto`, `move`,
`moveto`) will print data transfer stats at regular intervals to show
their progress.

This sets the interval.

The default is `1m`. Use 0 to disable.

If you set the stats interval then all commands can show stats.  This
can be useful when running other commands, `check` or `mount` for
example.

Stats are logged at `INFO` level by default which means they won't
show at default log level `NOTICE`.  Use `--stats-log-level NOTICE` or
`-v` to make them show.  See the [Logging section](#logging) for more
info on log levels.

### --stats-log-level string ###

Log level to show `--stats` output at.  This can be `DEBUG`, `INFO`,
`NOTICE`, or `ERROR`.  The default is `INFO`.  This means at the
default level of logging which is `NOTICE` the stats won't show - if
you want them to then use `-stats-log-level NOTICE`.  See the [Logging
section](#logging) for more info on log levels.

### --stats-unit=bits|bytes ###

By default, data transfer rates will be printed in bytes/second.

This option allows the data rate to be printed in bits/second.

Data transfer volume will still be reported in bytes.

The rate is reported as a binary unit, not SI unit. So 1 Mbit/s
equals 1,048,576 bits/s and not 1,000,000 bits/s.

The default is `bytes`.

### --suffix=SUFFIX ###

This is for use with `--backup-dir` only.  If this isn't set then
`--backup-dir` will move files with their original name.  If it is set
then the files will have SUFFIX added on to them.

See `--backup-dir` for more info.

### --syslog ###

On capable OSes (not Windows or Plan9) send all log output to syslog.

This can be useful for running rclone in a script or `rclone mount`.

### --syslog-facility string ###

If using `--syslog` this sets the syslog facility (eg `KERN`, `USER`).
See `man syslog` for a list of possible facilities.  The default
facility is `DAEMON`.

### --tpslimit float ###

Limit HTTP transactions per second to this. Default is 0 which is used
to mean unlimited transactions per second.

For example to limit rclone to 10 HTTP transactions per second use
`--tpslimit 10`, or to 1 transaction every 2 seconds use `--tpslimit
0.5`.

Use this when the number of transactions per second from rclone is
causing a problem with the cloud storage provider (eg getting you
banned or rate limited).

This can be very useful for `rclone mount` to control the behaviour of
applications using it.

See also `--tpslimit-burst`.

### --tpslimit-burst int ###

Max burst of transactions for `--tpslimit`. (default 1)

Normally `--tpslimit` will do exactly the number of transaction per
second specified.  However if you supply `--tps-burst` then rclone can
save up some transactions from when it was idle giving a burst of up
to the parameter supplied.

For example if you provide `--tpslimit-burst 10` then if rclone has
been idle for more than 10*`--tpslimit` then it can do 10 transactions
very quickly before they are limited again.

This may be used to increase performance of `--tpslimit` without
changing the long term average number of transactions per second.

### --track-renames ###

By default, rclone doesn't keep track of renamed files, so if you
rename a file locally then sync it to a remote, rclone will delete the
old file on the remote and upload a new copy.

If you use this flag, and the remote supports server side copy or
server side move, and the source and destination have a compatible
hash, then this will track renames during `sync`, `copy`, and `move`
operations and perform renaming server-side.

Files will be matched by size and hash - if both match then a rename
will be considered.

If the destination does not support server-side copy or move, rclone
will fall back to the default behaviour and log an error level message
to the console.

Note that `--track-renames` is incompatible with `--no-traverse` and
that it uses extra memory to keep track of all the rename candidates.

Note also that `--track-renames` is incompatible with
`--delete-before` and will select `--delete-after` instead of
`--delete-during`.

### --delete-(before,during,after) ###

This option allows you to specify when files on your destination are
deleted when you sync folders.

Specifying the value `--delete-before` will delete all files present
on the destination, but not on the source *before* starting the
transfer of any new or updated files. This uses two passes through the
file systems, one for the deletions and one for the copies.

Specifying `--delete-during` will delete files while checking and
uploading files. This is the fastest option and uses the least memory.

Specifying `--delete-after` (the default value) will delay deletion of
files until all new/updated files have been successfully transferred.
The files to be deleted are collected in the copy pass then deleted
after the copy pass has completed successfully.  The files to be
deleted are held in memory so this mode may use more memory.  This is
the safest mode as it will only delete files if there have been no
errors subsequent to that.  If there have been errors before the
deletions start then you will get the message `not deleting files as
there were IO errors`.

### --fast-list ###

When doing anything which involves a directory listing (eg `sync`,
`copy`, `ls` - in fact nearly every command), rclone normally lists a
directory and processes it before using more directory lists to
process any subdirectories.  This can be parallelised and works very
quickly using the least amount of memory.

However, some remotes have a way of listing all files beneath a
directory in one (or a small number) of transactions.  These tend to
be the bucket based remotes (eg S3, B2, GCS, Swift, Hubic).

If you use the `--fast-list` flag then rclone will use this method for
listing directories.  This will have the following consequences for
the listing:

  * It **will** use fewer transactions (important if you pay for them)
  * It **will** use more memory.  Rclone has to load the whole listing into memory.
  * It *may* be faster because it uses fewer transactions
  * It *may* be slower because it can't be parallelized

rclone should always give identical results with and without
`--fast-list`.

If you pay for transactions and can fit your entire sync listing into
memory then `--fast-list` is recommended.  If you have a very big sync
to do then don't use `--fast-list` otherwise you will run out of
memory.

If you use `--fast-list` on a remote which doesn't support it, then
rclone will just ignore it.

### --timeout=TIME ###

This sets the IO idle timeout.  If a transfer has started but then
becomes idle for this long it is considered broken and disconnected.

The default is `5m`.  Set to 0 to disable.

### --transfers=N ###

The number of file transfers to run in parallel.  It can sometimes be
useful to set this to a smaller number if the remote is giving a lot
of timeouts or bigger if you have lots of bandwidth and a fast remote.

The default is to run 4 file transfers in parallel.

### -u, --update ###

This forces rclone to skip any files which exist on the destination
and have a modified time that is newer than the source file.

If an existing destination file has a modification time equal (within
the computed modify window precision) to the source file's, it will be
updated if the sizes are different.

On remotes which don't support mod time directly the time checked will
be the uploaded time.  This means that if uploading to one of these
remotes, rclone will skip any files which exist on the destination and
have an uploaded time that is newer than the modification time of the
source file.

This can be useful when transferring to a remote which doesn't support
mod times directly as it is more accurate than a `--size-only` check
and faster than using `--checksum`.

### -v, -vv, --verbose ###

With `-v` rclone will tell you about each file that is transferred and
a small number of significant events.

With `-vv` rclone will become very verbose telling you about every
file it considers and transfers.  Please send bug reports with a log
with this setting.

### -V, --version ###

Prints the version number

Configuration Encryption
------------------------
Your configuration file contains information for logging in to 
your cloud services. This means that you should keep your 
`.rclone.conf` file in a secure location.

If you are in an environment where that isn't possible, you can
add a password to your configuration. This means that you will
have to enter the password every time you start rclone.

To add a password to your rclone configuration, execute `rclone config`.

```
>rclone config
Current remotes:

e) Edit existing remote
n) New remote
d) Delete remote
s) Set configuration password
q) Quit config
e/n/d/s/q>
```

Go into `s`, Set configuration password:
```
e/n/d/s/q> s
Your configuration is not encrypted.
If you add a password, you will protect your login information to cloud services.
a) Add Password
q) Quit to main menu
a/q> a
Enter NEW configuration password:
password:
Confirm NEW password:
password:
Password set
Your configuration is encrypted.
c) Change Password
u) Unencrypt configuration
q) Quit to main menu
c/u/q>
```

Your configuration is now encrypted, and every time you start rclone
you will now be asked for the password. In the same menu, you can
change the password or completely remove encryption from your
configuration.

There is no way to recover the configuration if you lose your password.

rclone uses [nacl secretbox](https://godoc.org/golang.org/x/crypto/nacl/secretbox) 
which in turn uses XSalsa20 and Poly1305 to encrypt and authenticate 
your configuration with secret-key cryptography.
The password is SHA-256 hashed, which produces the key for secretbox.
The hashed password is not stored.

While this provides very good security, we do not recommend storing
your encrypted rclone configuration in public if it contains sensitive
information, maybe except if you use a very strong password.

If it is safe in your environment, you can set the `RCLONE_CONFIG_PASS`
environment variable to contain your password, in which case it will be
used for decrypting the configuration.

You can set this for a session from a script.  For unix like systems
save this to a file called `set-rclone-password`:

```
#!/bin/echo Source this file don't run it

read -s RCLONE_CONFIG_PASS
export RCLONE_CONFIG_PASS
```

Then source the file when you want to use it.  From the shell you
would do `source set-rclone-password`.  It will then ask you for the
password and set it in the environment variable.

If you are running rclone inside a script, you might want to disable 
password prompts. To do that, pass the parameter 
`--ask-password=false` to rclone. This will make rclone fail instead
of asking for a password if `RCLONE_CONFIG_PASS` doesn't contain
a valid password.


Developer options
-----------------

These options are useful when developing or debugging rclone.  There
are also some more remote specific options which aren't documented
here which are used for testing.  These start with remote name eg
`--drive-test-option` - see the docs for the remote in question.

### --cpuprofile=FILE ###

Write CPU profile to file.  This can be analysed with `go tool pprof`.

### --dump-auth ###

Dump HTTP headers - will contain sensitive info such as
`Authorization:` headers - use `--dump-headers` to dump without
`Authorization:` headers.  Can be very verbose.  Useful for debugging
only.

### --dump-bodies ###

Dump HTTP headers and bodies - may contain sensitive info.  Can be
very verbose.  Useful for debugging only.

Note that the bodies are buffered in memory so don't use this for
enormous files.

### --dump-filters ###

Dump the filters to the output.  Useful to see exactly what include
and exclude options are filtering on.

### --dump-headers ###

Dump HTTP headers with `Authorization:` lines removed. May still
contain sensitive info.  Can be very verbose.  Useful for debugging
only.

Use `--dump-auth` if you do want the `Authorization:` headers.

### --memprofile=FILE ###

Write memory profile to file. This can be analysed with `go tool pprof`.

### --no-check-certificate=true/false ###

`--no-check-certificate` controls whether a client verifies the
server's certificate chain and host name.
If `--no-check-certificate` is true, TLS accepts any certificate
presented by the server and any host name in that certificate.
In this mode, TLS is susceptible to man-in-the-middle attacks.

This option defaults to `false`.

**This should be used only for testing.**

### --no-traverse ###

The `--no-traverse` flag controls whether the destination file system
is traversed when using the `copy` or `move` commands.
`--no-traverse` is not compatible with `sync` and will be ignored if
you supply it with `sync`.

If you are only copying a small number of files and/or have a large
number of files on the destination then `--no-traverse` will stop
rclone listing the destination and save time.

However, if you are copying a large number of files, especially if you
are doing a copy where lots of the files haven't changed and won't
need copying then you shouldn't use `--no-traverse`.

It can also be used to reduce the memory usage of rclone when copying
- `rclone --no-traverse copy src dst` won't load either the source or
destination listings into memory so will use the minimum amount of
memory.

Filtering
---------

For the filtering options

  * `--delete-excluded`
  * `--filter`
  * `--filter-from`
  * `--exclude`
  * `--exclude-from`
  * `--include`
  * `--include-from`
  * `--files-from`
  * `--min-size`
  * `--max-size`
  * `--min-age`
  * `--max-age`
  * `--dump-filters`

See the [filtering section](https://rclone.org/filtering/).

Logging
-------

rclone has 4 levels of logging, `Error`, `Notice`, `Info` and `Debug`.

By default, rclone logs to standard error.  This means you can redirect
standard error and still see the normal output of rclone commands (eg
`rclone ls`).

By default, rclone will produce `Error` and `Notice` level messages.

If you use the `-q` flag, rclone will only produce `Error` messages.

If you use the `-v` flag, rclone will produce `Error`, `Notice` and
`Info` messages.

If you use the `-vv` flag, rclone will produce `Error`, `Notice`,
`Info` and `Debug` messages.

You can also control the log levels with the `--log-level` flag.

If you use the `--log-file=FILE` option, rclone will redirect `Error`,
`Info` and `Debug` messages along with standard error to FILE.

If you use the `--syslog` flag then rclone will log to syslog and the
`--syslog-facility` control which facility it uses.

Rclone prefixes all log messages with their level in capitals, eg INFO
which makes it easy to grep the log file for different kinds of
information.

Exit Code
---------

If any errors occur during the command execution, rclone will exit with a
non-zero exit code.  This allows scripts to detect when rclone
operations have failed.

During the startup phase, rclone will exit immediately if an error is
detected in the configuration.  There will always be a log message
immediately before exiting.

When rclone is running it will accumulate errors as it goes along, and
only exit with a non-zero exit code if (after retries) there were
still failed transfers.  For every error counted there will be a high
priority log message (visible with `-q`) showing the message and
which file caused the problem. A high priority message is also shown
when starting a retry so the user can see that any previous error
messages may not be valid after the retry. If rclone has done a retry
it will log a high priority message if the retry was successful.

Environment Variables
---------------------

Rclone can be configured entirely using environment variables.  These
can be used to set defaults for options or config file entries.

### Options ###

Every option in rclone can have its default set by environment
variable.

To find the name of the environment variable, first, take the long
option name, strip the leading `--`, change `-` to `_`, make
upper case and prepend `RCLONE_`.

For example, to always set `--stats 5s`, set the environment variable
`RCLONE_STATS=5s`.  If you set stats on the command line this will
override the environment variable setting.

Or to always use the trash in drive `--drive-use-trash`, set
`RCLONE_DRIVE_USE_TRASH=true`.

The same parser is used for the options and the environment variables
so they take exactly the same form.

### Config file ###

You can set defaults for values in the config file on an individual
remote basis.  If you want to use this feature, you will need to
discover the name of the config items that you want.  The easiest way
is to run through `rclone config` by hand, then look in the config
file to see what the values are (the config file can be found by
looking at the help for `--config` in `rclone help`).

To find the name of the environment variable, you need to set, take
`RCLONE_` + name of remote + `_` + name of config file option and make
it all uppercase.

For example, to configure an S3 remote named `mys3:` without a config
file (using unix ways of setting environment variables):

```
$ export RCLONE_CONFIG_MYS3_TYPE=s3
$ export RCLONE_CONFIG_MYS3_ACCESS_KEY_ID=XXX
$ export RCLONE_CONFIG_MYS3_SECRET_ACCESS_KEY=XXX
$ rclone lsd MYS3:
          -1 2016-09-21 12:54:21        -1 my-bucket
$ rclone listremotes | grep mys3
mys3:
```

Note that if you want to create a remote using environment variables
you must create the `..._TYPE` variable as above.

### Other environment variables ###

  * RCLONE_CONFIG_PASS` set to contain your config file password (see [Configuration Encryption](#configuration-encryption) section)
  * HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or the lowercase versions thereof).
    * HTTPS_PROXY takes precedence over HTTP_PROXY for https requests.
    * The environment values may be either a complete URL or a "host[:port]" for, in which case the "http" scheme is assumed.

# Configuring rclone on a remote / headless machine #

Some of the configurations (those involving oauth2) require an
Internet connected web browser.

If you are trying to set rclone up on a remote or headless box with no
browser available on it (eg a NAS or a server in a datacenter) then
you will need to use an alternative means of configuration.  There are
two ways of doing it, described below.

## Configuring using rclone authorize ##

On the headless box

```
...
Remote config
Use auto config?
 * Say Y if not sure
 * Say N if you are working on a remote or headless machine
y) Yes
n) No
y/n> n
For this to work, you will need rclone available on a machine that has a web browser available.
Execute the following on your machine:
	rclone authorize "amazon cloud drive"
Then paste the result below:
result>
```

Then on your main desktop machine

```
rclone authorize "amazon cloud drive"
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access
Waiting for code...
Got code
Paste the following into your remote machine --->
SECRET_TOKEN
<---End paste
```

Then back to the headless box, paste in the code

```
result> SECRET_TOKEN
--------------------
[acd12]
client_id = 
client_secret = 
token = SECRET_TOKEN
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d>
```

## Configuring by copying the config file ##

Rclone stores all of its config in a single configuration file.  This
can easily be copied to configure a remote rclone.

So first configure rclone on your desktop machine

    rclone config

to set up the config file.

Find the config file by running `rclone -h` and looking for the help for the `--config` option

```
$ rclone -h
[snip]
      --config="/home/user/.rclone.conf": Config file.
[snip]
```

Now transfer it to the remote box (scp, cut paste, ftp, sftp etc) and
place it in the correct place (use `rclone -h` on the remote box to
find out where).

# Filtering, includes and excludes #

Rclone has a sophisticated set of include and exclude rules. Some of
these are based on patterns and some on other things like file size.

The filters are applied for the `copy`, `sync`, `move`, `ls`, `lsl`,
`md5sum`, `sha1sum`, `size`, `delete` and `check` operations.
Note that `purge` does not obey the filters.

Each path as it passes through rclone is matched against the include
and exclude rules like `--include`, `--exclude`, `--include-from`,
`--exclude-from`, `--filter`, or `--filter-from`. The simplest way to
try them out is using the `ls` command, or `--dry-run` together with
`-v`.

## Patterns ##

The patterns used to match files for inclusion or exclusion are based
on "file globs" as used by the unix shell.

If the pattern starts with a `/` then it only matches at the top level
of the directory tree, **relative to the root of the remote** (not
necessarily the root of the local drive). If it doesn't start with `/`
then it is matched starting at the **end of the path**, but it will
only match a complete path element:

    file.jpg  - matches "file.jpg"
              - matches "directory/file.jpg"
              - doesn't match "afile.jpg"
              - doesn't match "directory/afile.jpg"
    /file.jpg - matches "file.jpg" in the root directory of the remote
              - doesn't match "afile.jpg"
              - doesn't match "directory/file.jpg"

**Important** Note that you must use `/` in patterns and not `\` even
if running on Windows.

A `*` matches anything but not a `/`.

    *.jpg  - matches "file.jpg"
           - matches "directory/file.jpg"
           - doesn't match "file.jpg/something"

Use `**` to match anything, including slashes (`/`).

    dir/** - matches "dir/file.jpg"
           - matches "dir/dir1/dir2/file.jpg"
           - doesn't match "directory/file.jpg"
           - doesn't match "adir/file.jpg"

A `?` matches any character except a slash `/`.

    l?ss  - matches "less"
          - matches "lass"
          - doesn't match "floss"

A `[` and `]` together make a a character class, such as `[a-z]` or
`[aeiou]` or `[[:alpha:]]`.  See the [go regexp
docs](https://golang.org/pkg/regexp/syntax/) for more info on these.

    h[ae]llo - matches "hello"
             - matches "hallo"
             - doesn't match "hullo"

A `{` and `}` define a choice between elements.  It should contain a
comma seperated list of patterns, any of which might match.  These
patterns can contain wildcards.

    {one,two}_potato - matches "one_potato"
                     - matches "two_potato"
                     - doesn't match "three_potato"
                     - doesn't match "_potato"

Special characters can be escaped with a `\` before them.

    \*.jpg       - matches "*.jpg"
    \\.jpg       - matches "\.jpg"
    \[one\].jpg  - matches "[one].jpg"

Note also that rclone filter globs can only be used in one of the
filter command line flags, not in the specification of the remote, so
`rclone copy "remote:dir*.jpg" /path/to/dir` won't work - what is
required is `rclone --include "*.jpg" copy remote:dir /path/to/dir`

### Directories ###

Rclone keeps track of directories that could match any file patterns.

Eg if you add the include rule

    /a/*.jpg

Rclone will synthesize the directory include rule

    /a/

If you put any rules which end in `/` then it will only match
directories.

Directory matches are **only** used to optimise directory access
patterns - you must still match the files that you want to match.
Directory matches won't optimise anything on bucket based remotes (eg
s3, swift, google compute storage, b2) which don't have a concept of
directory.

### Differences between rsync and rclone patterns ###

Rclone implements bash style `{a,b,c}` glob matching which rsync doesn't.

Rclone always does a wildcard match so `\` must always escape a `\`.

## How the rules are used ##

Rclone maintains a combined list of include rules and exclude rules.

Each file is matched in order, starting from the top, against the rule
in the list until it finds a match.  The file is then included or
excluded according to the rule type.

If the matcher fails to find a match after testing against all the
entries in the list then the path is included.

For example given the following rules, `+` being include, `-` being
exclude,

    - secret*.jpg
    + *.jpg
    + *.png
    + file2.avi
    - *

This would include

  * `file1.jpg`
  * `file3.png`
  * `file2.avi`

This would exclude

  * `secret17.jpg`
  * non `*.jpg` and `*.png`

A similar process is done on directory entries before recursing into
them.  This only works on remotes which have a concept of directory
(Eg local, google drive, onedrive, amazon drive) and not on bucket
based remotes (eg s3, swift, google compute storage, b2).

## Adding filtering rules ##

Filtering rules are added with the following command line flags.

### Repeating options ##

You can repeat the following options to add more than one rule of that
type.

  * `--include`
  * `--include-from`
  * `--exclude`
  * `--exclude-from`
  * `--filter`
  * `--filter-from`

Note that all the options of the same type are processed together in
the order above, regardless of what order they were placed on the
command line.

So all `--include` options are processed first in the order they
appeared on the command line, then all `--include-from` options etc.

To mix up the order includes and excludes, the `--filter` flag can be
used.

### `--exclude` - Exclude files matching pattern ###

Add a single exclude rule with `--exclude`.

This flag can be repeated.  See above for the order the flags are
processed in.

Eg `--exclude *.bak` to exclude all bak files from the sync.

### `--exclude-from` - Read exclude patterns from file ###

Add exclude rules from a file.

This flag can be repeated.  See above for the order the flags are
processed in.

Prepare a file like this `exclude-file.txt`

    # a sample exclude rule file
    *.bak
    file2.jpg

Then use as `--exclude-from exclude-file.txt`.  This will sync all
files except those ending in `bak` and `file2.jpg`.

This is useful if you have a lot of rules.

### `--include` - Include files matching pattern ###

Add a single include rule with `--include`.

This flag can be repeated.  See above for the order the flags are
processed in.

Eg `--include *.{png,jpg}` to include all `png` and `jpg` files in the
backup and no others.

This adds an implicit `--exclude *` at the very end of the filter
list. This means you can mix `--include` and `--include-from` with the
other filters (eg `--exclude`) but you must include all the files you
want in the include statement.  If this doesn't provide enough
flexibility then you must use `--filter-from`.

### `--include-from` - Read include patterns from file ###

Add include rules from a file.

This flag can be repeated.  See above for the order the flags are
processed in.

Prepare a file like this `include-file.txt`

    # a sample include rule file
    *.jpg
    *.png
    file2.avi

Then use as `--include-from include-file.txt`.  This will sync all
`jpg`, `png` files and `file2.avi`.

This is useful if you have a lot of rules.

This adds an implicit `--exclude *` at the very end of the filter
list. This means you can mix `--include` and `--include-from` with the
other filters (eg `--exclude`) but you must include all the files you
want in the include statement.  If this doesn't provide enough
flexibility then you must use `--filter-from`.

### `--filter` - Add a file-filtering rule ###

This can be used to add a single include or exclude rule.  Include
rules start with `+ ` and exclude rules start with `- `.  A special
rule called `!` can be used to clear the existing rules.

This flag can be repeated.  See above for the order the flags are
processed in.

Eg `--filter "- *.bak"` to exclude all bak files from the sync.

### `--filter-from` - Read filtering patterns from a file ###

Add include/exclude rules from a file.

This flag can be repeated.  See above for the order the flags are
processed in.

Prepare a file like this `filter-file.txt`

    # a sample filter rule file
    - secret*.jpg
    + *.jpg
    + *.png
    + file2.avi
    - /dir/Trash/**
    + /dir/**
    # exclude everything else
    - *

Then use as `--filter-from filter-file.txt`.  The rules are processed
in the order that they are defined.

This example will include all `jpg` and `png` files, exclude any files
matching `secret*.jpg` and include `file2.avi`.  It will also include
everything in the directory `dir` at the root of the sync, except
`dir/Trash` which it will exclude.  Everything else will be excluded
from the sync.

### `--files-from` - Read list of source-file names ###

This reads a list of file names from the file passed in and **only**
these files are transferred.  The filtering rules are ignored
completely if you use this option.

This option can be repeated to read from more than one file.  These
are read in the order that they are placed on the command line.

Prepare a file like this `files-from.txt`

    # comment
    file1.jpg
    file2.jpg

Then use as `--files-from files-from.txt`.  This will only transfer
`file1.jpg` and `file2.jpg` providing they exist.

For example, let's say you had a few files you want to back up
regularly with these absolute paths:

    /home/user1/important
    /home/user1/dir/file
    /home/user2/stuff

To copy these you'd find a common subdirectory - in this case `/home`
and put the remaining files in `files-from.txt` with or without
leading `/`, eg

    user1/important
    user1/dir/file
    user2/stuff

You could then copy these to a remote like this

    rclone copy --files-from files-from.txt /home remote:backup

The 3 files will arrive in `remote:backup` with the paths as in the
`files-from.txt`.

You could of course choose `/` as the root too in which case your
`files-from.txt` might look like this.

    /home/user1/important
    /home/user1/dir/file
    /home/user2/stuff

And you would transfer it like this

    rclone copy --files-from files-from.txt / remote:backup

In this case there will be an extra `home` directory on the remote.

### `--min-size` - Don't transfer any file smaller than this ###

This option controls the minimum size file which will be transferred.
This defaults to `kBytes` but a suffix of `k`, `M`, or `G` can be
used.

For example `--min-size 50k` means no files smaller than 50kByte will be
transferred.

### `--max-size` - Don't transfer any file larger than this ###

This option controls the maximum size file which will be transferred.
This defaults to `kBytes` but a suffix of `k`, `M`, or `G` can be
used.

For example `--max-size 1G` means no files larger than 1GByte will be
transferred.

### `--max-age` - Don't transfer any file older than this ###

This option controls the maximum age of files to transfer.  Give in
seconds or with a suffix of:

  * `ms` - Milliseconds
  * `s` - Seconds
  * `m` - Minutes
  * `h` - Hours
  * `d` - Days
  * `w` - Weeks
  * `M` - Months
  * `y` - Years

For example `--max-age 2d` means no files older than 2 days will be
transferred.

### `--min-age` - Don't transfer any file younger than this ###

This option controls the minimum age of files to transfer.  Give in
seconds or with a suffix (see `--max-age` for list of suffixes)

For example `--min-age 2d` means no files younger than 2 days will be
transferred.

### `--delete-excluded` - Delete files on dest excluded from sync ###

**Important** this flag is dangerous - use with `--dry-run` and `-v` first.

When doing `rclone sync` this will delete any files which are excluded
from the sync on the destination.

If for example you did a sync from `A` to `B` without the `--min-size 50k` flag

    rclone sync A: B:

Then you repeated it like this with the `--delete-excluded`

    rclone --min-size 50k --delete-excluded sync A: B:

This would delete all files on `B` which are less than 50 kBytes as
these are now excluded from the sync.

Always test first with `--dry-run` and `-v` before using this flag.

### `--dump-filters` - dump the filters to the output ###

This dumps the defined filters to the output as regular expressions.

Useful for debugging.

## Quoting shell metacharacters ##

The examples above may not work verbatim in your shell as they have
shell metacharacters in them (eg `*`), and may require quoting.

Eg linux, OSX

  * `--include \*.jpg`
  * `--include '*.jpg'`
  * `--include='*.jpg'`

In Windows the expansion is done by the command not the shell so this
should work fine

  * `--include *.jpg`

# Overview of cloud storage systems #

Each cloud storage system is slighly different.  Rclone attempts to
provide a unified interface to them, but some underlying differences
show through.

## Features ##

Here is an overview of the major features of each cloud storage system.

| Name                         | Hash        | ModTime | Case Insensitive | Duplicate Files | MIME Type |

| Google Cloud Storage         | MD5         | Yes     | No               | No              | R/W       |

| Yandex Disk                  | MD5         | Yes     | No               | No              | R/W       |
| The local filesystem         | All         | Yes     | Depends          | No              | -         |

### Hash ###

The cloud storage system supports various hash types of the objects.
The hashes are used when transferring data as an integrity check and
can be specifically used with the `--checksum` flag in syncs and in
the `check` command.

To use the verify checksums when transferring between cloud storage
systems they must support a common hash type.

† Note that Dropbox supports [its own custom
hash](https://www.dropbox.com/developers/reference/content-hash).
This is an SHA256 sum of all the 4MB block SHA256s.

‡ SFTP supports checksums if the same login has shell access and `md5sum`
or `sha1sum` as well as `echo` are in the remote's PATH.

### ModTime ###

The cloud storage system supports setting modification times on
objects.  If it does then this enables a using the modification times
as part of the sync.  If not then only the size will be checked by
default, though the MD5SUM can be checked with the `--checksum` flag.

All cloud storage systems support some kind of date on the object and
these will be set when transferring from the cloud storage system.

### Case Insensitive ###

If a cloud storage systems is case sensitive then it is possible to
have two files which differ only in case, eg `file.txt` and
`FILE.txt`.  If a cloud storage system is case insensitive then that
isn't possible.

This can cause problems when syncing between a case insensitive
system and a case sensitive system.  The symptom of this is that no
matter how many times you run the sync it never completes fully.

The local filesystem and SFTP may or may not be case sensitive
depending on OS.

  * Windows - usually case insensitive, though case is preserved
  * OSX - usually case insensitive, though it is possible to format case sensitive
  * Linux - usually case sensitive, but there are case insensitive file systems (eg FAT formatted USB keys)

Most of the time this doesn't cause any problems as people tend to
avoid files whose name differs only by case even on case sensitive
systems.

### Duplicate files ###

If a cloud storage system allows duplicate files then it can have two
objects with the same name.

This confuses rclone greatly when syncing - use the `rclone dedupe`
command to rename or remove duplicates.

### MIME Type ###

MIME types (also known as media types) classify types of documents
using a simple text classification, eg `text/html` or
`application/pdf`.

Some cloud storage systems support reading (`R`) the MIME type of
objects and some support writing (`W`) the MIME type of objects.

The MIME type can be important if you are serving files directly to
HTTP from the storage system.

If you are copying from a remote which supports reading (`R`) to a
remote which supports writing (`W`) then rclone will preserve the MIME
types.  Otherwise they will be guessed from the extension, or the
remote itself may assign the MIME type.

## Optional Features ##

All the remotes support a basic set of features, but there are some
optional features supported by some remotes used to make some
operations more efficient.

### Purge ###

This deletes a directory quicker than just deleting all the files in
the directory.

† Note Swift and Hubic implement this in order to delete directory
markers but they don't actually have a quicker way of deleting files
other than deleting them individually.

### Copy ###

Used when copying an object to and from the same remote.  This known
as a server side copy so you can copy a file without downloading it
and uploading it again.  It is used if you use `rclone copy` or
`rclone move` if the remote doesn't support `Move` directly.

If the server doesn't support `Copy` directly then for copy operations
the file is downloaded then re-uploaded.

### Move ###

Used when moving/renaming an object on the same remote.  This is known
as a server side move of a file.  This is used in `rclone move` if the
server doesn't support `DirMove`.

If the server isn't capable of `Move` then rclone simulates it with
`Copy` then delete.  If the server doesn't support `Copy` then rclone
will download the file and re-upload it.

### DirMove ###

This is used to implement `rclone move` to move a directory if
possible.  If it isn't then it will use `Move` on each file (which
falls back to `Copy` then download and upload - see `Move` section).

### CleanUp ###

This is used for emptying the trash for a remote by `rclone cleanup`.

If the server can't do `CleanUp` then `rclone cleanup` will return an
error.

### ListR ###

The remote supports a recursive list to list all the contents beneath
a directory quickly.  This enables the `--fast-list` flag to work.
See the [rclone docs](/docs/#fast-list) for more details.

### StreamUpload ###

Some remotes allow files to be uploaded without knowing the file size
in advance. This allows certain operations to work without spooling the
file to local disk first, e.g. `rclone rcat`.

Amazon Drive
-----------------------------------------

Paths are specified as `remote:path`

Paths may be as deep as required, eg `remote:directory/subdirectory`.

The initial setup for Amazon Drive involves getting a token from
Amazon which you need to do in your browser.  `rclone config` walks
you through it.

The configuration process for Amazon Drive may involve using an [oauth
proxy](https://github.com/ncw/oauthproxy). This is used to keep the
Amazon credentials out of the source code.  The proxy runs in Google's
very secure App Engine environment and doesn't store any credentials
which pass through it.

**NB** rclone doesn't not currently have its own Amazon Drive
credentials (see [the
forum](https://forum.rclone.org/t/rclone-has-been-banned-from-amazon-drive/)
for why) so you will either need to have your own `client_id` and
`client_secret` with Amazon Drive, or use a a third party ouath proxy
in which case you will need to enter `client_id`, `client_secret`,
`auth_url` and `token_url`.

Note also if you are not using Amazon's `auth_url` and `token_url`,
(ie you filled in something for those) then if setting up on a remote
machine you can only use the [copying the config method of
configuration](https://rclone.org/remote_setup/#configuring-by-copying-the-config-file)
- `rclone authorize` will not work.

Here is an example of how to make a remote called `remote`.  First run:

     rclone config

This will guide you through an interactive setup process:

```

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

See the [remote setup docs](https://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the
token as returned from Amazon. This only runs from the moment it
opens your browser to the moment you get back the verification
code.  This is on `http://127.0.0.1:53682/` and this it may require
you to unblock it temporarily if you are running a host firewall.

Once configured you can then use `rclone` like this,

List directories in top level of your Amazon Drive

    rclone lsd remote:

List all the files in your Amazon Drive

    rclone ls remote:

To copy a local directory to an Amazon Drive directory called backup

    rclone copy /home/source remote:backup

### Modified time and MD5SUMs ###

Amazon Drive doesn't allow modification times to be changed via
the API so these won't be accurate or used for syncing.

It does store MD5SUMs so for a more accurate sync, you can use the
`--checksum` flag.

### Deleting files ###

Any files you delete with rclone will end up in the trash.  Amazon
don't provide an API to permanently delete files, nor to empty the
trash, so you will have to do that with one of Amazon's apps or via
the Amazon Drive website. As of November 17, 2016, files are 
automatically deleted by Amazon from the trash after 30 days.

### Using with non `.com` Amazon accounts ###

Let's say you usually use `amazon.co.uk`. When you authenticate with
rclone it will take you to an `amazon.com` page to log in.  Your
`amazon.co.uk` email and password should work here just fine.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --acd-templink-threshold=SIZE ####

Files this size or more will be downloaded via their `tempLink`. This
is to work around a problem with Amazon Drive which blocks downloads
of files bigger than about 10GB.  The default for this is 9GB which
shouldn't need to be changed.

To download files above this threshold, rclone requests a `tempLink`
which downloads the file through a temporary URL directly from the
underlying S3 storage.

#### --acd-upload-wait-per-gb=TIME ####

Sometimes Amazon Drive gives an error when a file has been fully
uploaded but the file appears anyway after a little while.  This
happens sometimes for files over 1GB in size and nearly every time for
files bigger than 10GB. This parameter controls the time rclone waits
for the file to appear.

The default value for this parameter is 3 minutes per GB, so by
default it will wait 3 minutes for every GB uploaded to see if the
file appears.

You can disable this feature by setting it to 0. This may cause
conflict errors as rclone retries the failed upload but the file will
most likely appear correctly eventually.

These values were determined empirically by observing lots of uploads
of big files for a range of file sizes.

Upload with the `-v` flag to see more info about what rclone is doing
in this situation.

### Limitations ###

Note that Amazon Drive is case insensitive so you can't have a
file called "Hello.doc" and one called "hello.doc".

Amazon Drive has rate limiting so you may notice errors in the
sync (429 errors).  rclone will automatically retry the sync up to 3
times by default (see `--retries` flag) which should hopefully work
around this problem.

Amazon Drive has an internal limit of file sizes that can be uploaded
to the service. This limit is not officially published, but all files
larger than this will fail.

At the time of writing (Jan 2016) is in the area of 50GB per file.
This means that larger files are likely to fail.

Unfortunately there is no way for rclone to see that this failure is
because of file size, so it will retry the operation, as any other
failure. To avoid this problem, use `--max-size 50000M` option to limit
the maximum size of uploaded files. Note that `--max-size` does not split
files into segments, it only ignores files over this size.

Amazon S3
---------------------------------------

Paths are specified as `remote:bucket` (or `remote:` for the `lsd`
command.)  You may put subdirectories in too, eg `remote:bucket/path/to/dir`.

Here is an example of making an s3 configuration.  First run

    rclone config

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote

```

This remote is called `remote` and can now be used like this

See all buckets

    rclone lsd remote:

Make a new bucket

    rclone mkdir remote:bucket

List the contents of a bucket

    rclone ls remote:bucket

Sync `/home/local/directory` to the remote bucket, deleting any excess
files in the bucket.

    rclone sync /home/local/directory remote:bucket

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Modified time ###

The modified time is stored as metadata on the object as
`X-Amz-Meta-Mtime` as floating point since the epoch accurate to 1 ns.

### Multipart uploads ###

rclone supports multipart uploads with S3 which means that it can
upload files bigger than 5GB. Note that files uploaded with multipart
upload don't have an MD5SUM.

### Buckets and Regions ###

With Amazon S3 you can list buckets (`rclone lsd`) using any region,
but you can only access the content of a bucket from the region it was
created in.  If you attempt to access a bucket from the wrong region,
you will get an error, `incorrect region, the bucket is not in 'XXX'
region`.

### Authentication ###
There are two ways to supply `rclone` with a set of AWS
credentials. In order of precedence:

 - Directly in the rclone configuration file (as configured by `rclone config`)
   - set `access_key_id` and `secret_access_key`. `session_token` can be
     optionally set when using AWS STS.
 - Runtime configuration:
   - set `env_auth` to `true` in the config file
   - Exporting the following environment variables before running `rclone`
     - Access Key ID: `AWS_ACCESS_KEY_ID` or `AWS_ACCESS_KEY`
     - Secret Access Key: `AWS_SECRET_ACCESS_KEY` or `AWS_SECRET_KEY`
     - Session Token: `AWS_SESSION_TOKEN`
   - Running `rclone` on an EC2 instance with an IAM role

If none of these option actually end up providing `rclone` with AWS
credentials then S3 interaction will be non-authenticated (see below).

### S3 Permissions ###

When using the `sync` subcommand of `rclone` the following minimum 
permissions are required to be available on the bucket being written to:

* `ListBucket`
* `DeleteObject`
* `GetObject`
* `PutObject`
* `PutObjectACL`

Example policy:

```
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::USER_SID:user/USER_NAME"
            },
            "Action": [
                "s3:ListBucket",
                "s3:DeleteObject",
                "s3:GetObject",
                "s3:PutObject",
                "s3:PutObjectAcl"
            ],
            "Resource": [
              "arn:aws:s3:::BUCKET_NAME/*",
              "arn:aws:s3:::BUCKET_NAME"
            ]
        }
    ]
}
```

Notes on above:

1. This is a policy that can be used when creating bucket. It assumes
   that `USER_NAME` has been created.
2. The Resource entry must include both resource ARNs, as one implies 
   the bucket and the other implies the bucket's objects.

For reference, [here's an Ansible script](https://gist.github.com/ebridges/ebfc9042dd7c756cd101cfa807b7ae2b) 
that will generate one or more buckets that will work with `rclone sync`.

### Glacier ###

You can transition objects to glacier storage using a [lifecycle policy](http://docs.aws.amazon.com/AmazonS3/latest/user-guide/create-lifecycle.html).
The bucket can still be synced or copied into normally, but if rclone
tries to access the data you will see an error like below.

    2017/09/11 19:07:43 Failed to sync: failed to open source object: Object in GLACIER, restore first: path/to/file

In this case you need to [restore](http://docs.aws.amazon.com/AmazonS3/latest/user-guide/restore-archived-objects.html)
the object(s) in question before using rclone.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --s3-acl=STRING ####

Canned ACL used when creating buckets and/or storing objects in S3.

For more info visit the [canned ACL docs](https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#canned-acl).

#### --s3-storage-class=STRING ####

Storage class to upload new objects with.

Available options include:

 - STANDARD - default storage class
 - STANDARD_IA - for less frequently accessed data (e.g backups)
 - REDUCED_REDUNDANCY (only for noncritical, reproducible data, has lower redundancy)

### Anonymous access to public buckets ###

If you want to use rclone to access a public bucket, configure with a
blank `access_key_id` and `secret_access_key`.  Eg

```
No remotes found - make a new one
n) New remote
q) Quit config
n/q> n
name> anons3
What type of source is it?
Choose a number from below
 1) amazon cloud drive
 2) b2
 3) drive
 4) dropbox
 5) google cloud storage
 6) swift
 7) hubic
 8) local
 9) onedrive
10) s3
11) yandex
type> 10
Get AWS credentials from runtime (environment variables or EC2 meta data if no env vars). Only applies if access_key_id and secret_access_key is blank.
Choose a number from below, or type in your own value
 * Enter AWS credentials in the next step
 1) false
 * Get AWS credentials from the environment (env vars or IAM)
 2) true
env_auth> 1
AWS Access Key ID - leave blank for anonymous access or runtime credentials.
access_key_id>
AWS Secret Access Key (password) - leave blank for anonymous access or runtime credentials.
secret_access_key>
...
```

Then use it as normal with the name of the public bucket, eg

    rclone lsd anons3:1000genomes

You will be able to list and copy data but not upload it.

### Ceph ###

Ceph is an object storage system which presents an Amazon S3 interface.

To use rclone with ceph, you need to set the following parameters in
the config.

```
access_key_id = Whatever
secret_access_key = Whatever
endpoint = https://ceph.endpoint.goes.here/
region = other-v2-signature
```

Note also that Ceph sometimes puts `/` in the passwords it gives
users.  If you read the secret access key using the command line tools
you will get a JSON blob with the `/` escaped as `\/`.  Make sure you
only write `/` in the secret access key.

Eg the dump from Ceph looks something like this (irrelevant keys
removed).

```
{
    "user_id": "xxx",
    "display_name": "xxxx",
    "keys": [
        {
            "user": "xxx",
            "access_key": "xxxxxx",
            "secret_key": "xxxxxx\/xxxx"
        }
    ],
}
```

Because this is a json dump, it is encoding the `/` as `\/`, so if you
use the secret key as `xxxxxx/xxxx`  it will work fine.

### Minio ###

[Minio](https://minio.io/) is an object storage server built for cloud application developers and devops.

It is very easy to install and provides an S3 compatible server which can be used by rclone.

To use it, install Minio following the instructions [here](https://docs.minio.io/docs/minio-quickstart-guide).

When it configures itself Minio will print something like this

```
Endpoint:  http://192.168.1.106:9000  http://172.23.0.1:9000
AccessKey: USWUXHGYZQYFYFFIT3RE
SecretKey: MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03
Region:    us-east-1
SQS ARNs:  arn:minio:sqs:us-east-1:1:redis arn:minio:sqs:us-east-1:2:redis

Browser Access:
   http://192.168.1.106:9000  http://172.23.0.1:9000

Command-line Access: https://docs.minio.io/docs/minio-client-quickstart-guide
   $ mc config host add myminio http://192.168.1.106:9000 USWUXHGYZQYFYFFIT3RE MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03

Object API (Amazon S3 compatible):
   Go:         https://docs.minio.io/docs/golang-client-quickstart-guide
   Java:       https://docs.minio.io/docs/java-client-quickstart-guide
   Python:     https://docs.minio.io/docs/python-client-quickstart-guide
   JavaScript: https://docs.minio.io/docs/javascript-client-quickstart-guide
   .NET:       https://docs.minio.io/docs/dotnet-client-quickstart-guide

Drive Capacity: 26 GiB Free, 165 GiB Total
```

These details need to go into `rclone config` like this.  Note that it
is important to put the region in as stated above.

```
env_auth> 1
access_key_id> USWUXHGYZQYFYFFIT3RE
secret_access_key> MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03
region> us-east-1
endpoint> http://192.168.1.106:9000
location_constraint>
server_side_encryption>
```

Which makes the config file look like this

```
[minio]
env_auth = false
access_key_id = USWUXHGYZQYFYFFIT3RE
secret_access_key = MOJRH0mkL1IPauahWITSVvyDrQbEEIwljvmxdq03
region = us-east-1
endpoint = http://192.168.1.106:9000
location_constraint =
server_side_encryption =
```

So once set up, for example to copy files into a bucket

```
rclone copy /path/to/files minio:bucket
```

### Wasabi ###

[Wasabi](https://wasabi.com) is a cloud-based object storage service for a
broad range of applications and use cases. Wasabi is designed for
individuals and organizations that require a high-performance,
reliable, and secure data storage infrastructure at minimal cost.

Wasabi provides an S3 interface which can be configured for use with
rclone like this.

Backblaze B2
----------------------------------------

B2 is [Backblaze's cloud storage system](https://www.backblaze.com/b2/).

Paths are specified as `remote:bucket` (or `remote:` for the `lsd`
command.)  You may put subdirectories in too, eg `remote:bucket/path/to/dir`.

Here is an example of making a b2 configuration.  First run

    rclone config

This will guide you through an interactive setup process.  You will
need your account number (a short hex number) and key (a long hex
number) which you can get from the b2 control panel.

This remote is called `remote` and can now be used like this

See all buckets

    rclone lsd remote:

Make a new bucket

    rclone mkdir remote:bucket

List the contents of a bucket

    rclone ls remote:bucket

Sync `/home/local/directory` to the remote bucket, deleting any
excess files in the bucket.

    rclone sync /home/local/directory remote:bucket

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Modified time ###

The modified time is stored as metadata on the object as
`X-Bz-Info-src_last_modified_millis` as milliseconds since 1970-01-01
in the Backblaze standard.  Other tools should be able to use this as
a modified time.

Modified times are used in syncing and are fully supported except in
the case of updating a modification time on an existing object.  In
this case the object will be uploaded again as B2 doesn't have an API
method to set the modification time independent of doing an upload.

### SHA1 checksums ###

The SHA1 checksums of the files are checked on upload and download and
will be used in the syncing process.

Large files which are uploaded in chunks will store their SHA1 on the
object as `X-Bz-Info-large_file_sha1` as recommended by Backblaze.

### Transfers ###

Backblaze recommends that you do lots of transfers simultaneously for
maximum speed.  In tests from my SSD equiped laptop the optimum
setting is about `--transfers 32` though higher numbers may be used
for a slight speed improvement. The optimum number for you may vary
depending on your hardware, how big the files are, how much you want
to load your computer, etc.  The default of `--transfers 4` is
definitely too low for Backblaze B2 though.

Note that uploading big files (bigger than 200 MB by default) will use
a 96 MB RAM buffer by default.  There can be at most `--transfers` of
these in use at any moment, so this sets the upper limit on the memory
used.

### Versions ###

When rclone uploads a new version of a file it creates a [new version
of it](https://www.backblaze.com/b2/docs/file_versions.html).
Likewise when you delete a file, the old version will be marked hidden
and still be available.  Conversely, you may opt in to a "hard delete"
of files with the `--b2-hard-delete` flag which would permanently remove
the file instead of hiding it.

Old versions of files, where available, are visible using the 
`--b2-versions` flag.

If you wish to remove all the old versions then you can use the
`rclone cleanup remote:bucket` command which will delete all the old
versions of files, leaving the current ones intact.  You can also
supply a path and only old versions under that path will be deleted,
eg `rclone cleanup remote:bucket/path/to/stuff`.

When you `purge` a bucket, the current and the old versions will be
deleted then the bucket will be deleted.

However `delete` will cause the current versions of the files to
become hidden old versions.

Here is a session showing the listing and and retreival of an old
version followed by a `cleanup` of the old versions.

Show current version and all the versions with `--b2-versions` flag.

```
$ rclone -q ls b2:cleanup-test
        9 one.txt

$ rclone -q --b2-versions ls b2:cleanup-test
        9 one.txt
        8 one-v2016-07-04-141032-000.txt
       16 one-v2016-07-04-141003-000.txt
       15 one-v2016-07-02-155621-000.txt
```

Retreive an old verson

```
$ rclone -q --b2-versions copy b2:cleanup-test/one-v2016-07-04-141003-000.txt /tmp

$ ls -l /tmp/one-v2016-07-04-141003-000.txt
-rw-rw-r-- 1 ncw ncw 16 Jul  2 17:46 /tmp/one-v2016-07-04-141003-000.txt
```

Clean up all the old versions and show that they've gone.

```
$ rclone -q cleanup b2:cleanup-test

$ rclone -q ls b2:cleanup-test
        9 one.txt

$ rclone -q --b2-versions ls b2:cleanup-test
        9 one.txt
```

### Data usage ###

It is useful to know how many requests are sent to the server in different scenarios.

All copy commands send the following 4 requests:

```
/b2api/v1/b2_authorize_account
/b2api/v1/b2_create_bucket
/b2api/v1/b2_list_buckets
/b2api/v1/b2_list_file_names
```

The `b2_list_file_names` request will be sent once for every 1k files
in the remote path, providing the checksum and modification time of
the listed files. As of version 1.33 issue
[#818](https://github.com/ncw/rclone/issues/818) causes extra requests
to be sent when using B2 with Crypt. When a copy operation does not
require any files to be uploaded, no more requests will be sent.

Uploading files that do not require chunking, will send 2 requests per
file upload:

```
/b2api/v1/b2_get_upload_url
/b2api/v1/b2_upload_file/
```

Uploading files requiring chunking, will send 2 requests (one each to
start and finish the upload) and another 2 requests for each chunk:

```
/b2api/v1/b2_start_large_file
/b2api/v1/b2_get_upload_part_url
/b2api/v1/b2_upload_part/
/b2api/v1/b2_finish_large_file
```

### B2 with crypt ###

When using B2 with `crypt` files are encrypted into a temporary
location and streamed from there. This is required to calculate the
encrypted file's checksum before beginning the upload. On Windows the
%TMPDIR% environment variable is used as the temporary location. If
the file requires chunking, both the chunking and encryption will take
place in memory.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --b2-chunk-size valuee=SIZE ####

When uploading large files chunk the file into this size.  Note that
these chunks are buffered in memory and there might a maximum of
`--transfers` chunks in progress at once.  5,000,000 Bytes is the
minimim size (default 96M).

#### --b2-upload-cutoff=SIZE ####

Cutoff for switching to chunked upload (default 190.735 MiB == 200
MB). Files above this size will be uploaded in chunks of
`--b2-chunk-size`.

This value should be set no larger than 4.657GiB (== 5GB) as this is
the largest file size that can be uploaded.


#### --b2-test-mode=FLAG ####

This is for debugging purposes only.

Setting FLAG to one of the strings below will cause b2 to return
specific errors for debugging purposes.

  * `fail_some_uploads`
  * `expire_some_account_authorization_tokens`
  * `force_cap_exceeded`

These will be set in the `X-Bz-Test-Mode` header which is documented
in the [b2 integrations
checklist](https://www.backblaze.com/b2/docs/integration_checklist.html).

#### --b2-versions ####

When set rclone will show and act on older versions of files.  For example

Listing without `--b2-versions`

```
$ rclone -q ls b2:cleanup-test
        9 one.txt
```

And with

```
$ rclone -q --b2-versions ls b2:cleanup-test
        9 one.txt
        8 one-v2016-07-04-141032-000.txt
       16 one-v2016-07-04-141003-000.txt
       15 one-v2016-07-02-155621-000.txt
```

Showing that the current version is unchanged but older versions can
be seen.  These have the UTC date that they were uploaded to the
server to the nearest millisecond appended to them.

Note that when using `--b2-versions` no file write operations are
permitted, so you can't upload files or delete them.

Box
-----------------------------------------

Paths are specified as `remote:path`

Paths may be as deep as required, eg `remote:directory/subdirectory`.

The initial setup for Box involves getting a token from Box which you
need to do in your browser.  `rclone config` walks you through it.

Here is an example of how to make a remote called `remote`.  First run:

     rclone config

This will guide you through an interactive setup process:

```

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

See the [remote setup docs](https://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the
token as returned from Box. This only runs from the moment it opens
your browser to the moment you get back the verification code.  This
is on `http://127.0.0.1:53682/` and this it may require you to unblock
it temporarily if you are running a host firewall.

Once configured you can then use `rclone` like this,

List directories in top level of your Box

    rclone lsd remote:

List all the files in your Box

    rclone ls remote:

To copy a local directory to an Box directory called backup

    rclone copy /home/source remote:backup

### Invalid refresh token ###

According to the [box docs](https://developer.box.com/v2.0/docs/oauth-20#section-6-using-the-access-and-refresh-tokens):

> Each refresh_token is valid for one use in 60 days.

This means that if you

  * Don't use the box remote for 60 days
  * Copy the config file with a box refresh token in and use it in two places
  * Get an error on a token refresh

then rclone will return an error which includes the text `Invalid
refresh token`.

To fix this you will need to use oauth2 again to update the refresh
token.  You can use the methods in [the remote setup
docs](https://rclone.org/remote_setup/), bearing in mind that if you use the copy the
config file method, you should not use that remote on the computer you
did the authentication on.

Here is how to do it.

```
$ rclone config

token = {"access_token":"YYY","token_type":"bearer","refresh_token":"YYY","expiry":"2017-07-23T12:22:29.259137901+01:00"}
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

### Modified time and hashes ###

Box allows modification times to be set on objects accurate to 1
second.  These will be used to detect whether objects need syncing or
not.

One drive supports SHA1 type hashes, so you can use the `--checksum`
flag.

### Transfers ###

For files above 50MB rclone will use a chunked transfer.  Rclone will
upload up to `--transfers` chunks at the same time (shared among all
the multipart uploads).  Chunks are buffered in memory and are
normally 8MB so increasing `--transfers` will increase memory use.

### Deleting files ###

Depending on the enterprise settings for your user, the item will
either be actually deleted from Box or moved to the trash.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --box-upload-cutoff=SIZE ####

Cutoff for switching to chunked upload - must be >= 50MB. The default
is 50MB.

### Limitations ###

Note that Box is case insensitive so you can't have a file called
"Hello.doc" and one called "hello.doc".

Box file names can't have the `\` character in.  rclone maps this to
and from an identical looking unicode equivalent `＼`.

Box only supports filenames up to 255 characters in length.

Crypt
----------------------------------------

The `crypt` remote encrypts and decrypts another remote.

To use it first set up the underlying remote following the config
instructions for that remote.  You can also use a local pathname
instead of a remote which will encrypt and decrypt from that directory
which might be useful for encrypting onto a USB stick for example.

First check your chosen remote is working - we'll call it
`remote:path` in these docs.  Note that anything inside `remote:path`
will be encrypted and anything outside won't.  This means that if you
are using a bucket based remote (eg S3, B2, swift) then you should
probably put the bucket in the remote `s3:bucket`. If you just use
`s3:` then rclone will make encrypted bucket names too (if using file
name encryption) which may or may not be what you want.

Now configure `crypt` using `rclone config`. We will call this one
`secret` to differentiate it from the `remote`.

```

filename_encryption = standard
password = *** ENCRYPTED ***
password2 = *** ENCRYPTED ***
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

**Important** The password is stored in the config file is lightly
obscured so it isn't immediately obvious what it is.  It is in no way
secure unless you use config file encryption.

A long passphrase is recommended, or you can use a random one.  Note
that if you reconfigure rclone with the same passwords/passphrases
elsewhere it will be compatible - all the secrets used are derived
from those two passwords/passphrases.

Note that rclone does not encrypt

  * file length - this can be calcuated within 16 bytes
  * modification time - used for syncing

## Specifying the remote ##

In normal use, make sure the remote has a `:` in. If you specify the
remote without a `:` then rclone will use a local directory of that
name.  So if you use a remote of `/path/to/secret/files` then rclone
will encrypt stuff to that directory.  If you use a remote of `name`
then rclone will put files in a directory called `name` in the current
directory.

If you specify the remote as `remote:path/to/dir` then rclone will
store encrypted files in `path/to/dir` on the remote. If you are using
file name encryption, then when you save files to
`secret:subdir/subfile` this will store them in the unencrypted path
`path/to/dir` but the `subdir/subpath` bit will be encrypted.

Note that unless you want encrypted bucket names (which are difficult
to manage because you won't know what directory they represent in web
interfaces etc), you should probably specify a bucket, eg
`remote:secretbucket` when using bucket based remotes such as S3,
Swift, Hubic, B2, GCS.

## Example ##

To test I made a little directory of files using "standard" file name
encryption.

```
plaintext/
├── file0.txt
├── file1.txt
└── subdir
    ├── file2.txt
    ├── file3.txt
    └── subsubdir
        └── file4.txt
```

Copy these to the remote and list them back

```
$ rclone -q copy plaintext secret:
$ rclone -q ls secret:
        7 file1.txt
        6 file0.txt
        8 subdir/file2.txt
       10 subdir/subsubdir/file4.txt
        9 subdir/file3.txt
```

Now see what that looked like when encrypted

```
$ rclone -q ls remote:path
       55 hagjclgavj2mbiqm6u6cnjjqcg
       54 v05749mltvv1tf4onltun46gls
       57 86vhrsv86mpbtd3a0akjuqslj8/dlj7fkq4kdq72emafg7a7s41uo
       58 86vhrsv86mpbtd3a0akjuqslj8/7uu829995du6o42n32otfhjqp4/b9pausrfansjth5ob3jkdqd4lc
       56 86vhrsv86mpbtd3a0akjuqslj8/8njh1sk437gttmep3p70g81aps
```

Note that this retains the directory structure which means you can do this

```
$ rclone -q ls secret:subdir
        8 file2.txt
        9 file3.txt
       10 subsubdir/file4.txt
```

If don't use file name encryption then the remote will look like this
- note the `.bin` extensions added to prevent the cloud provider
attempting to interpret the data.

```
$ rclone -q ls remote:path
       54 file0.txt.bin
       57 subdir/file3.txt.bin
       56 subdir/file2.txt.bin
       58 subdir/subsubdir/file4.txt.bin
       55 file1.txt.bin
```

### File name encryption modes ###

Here are some of the features of the file name encryption modes

Off

  * doesn't hide file names or directory structure
  * allows for longer file names (~246 characters)
  * can use sub paths and copy single files

Standard

  * file names encrypted
  * file names can't be as long (~156 characters)
  * can use sub paths and copy single files
  * directory structure visibile
  * identical files names will have identical uploaded names
  * can use shortcuts to shorten the directory recursion

Obfuscation

This is a simple "rotate" of the filename, with each file having a rot
distance based on the filename. We store the distance at the beginning
of the filename. So a file called "hello" may become "53.jgnnq"

This is not a strong encryption of filenames, but it may stop automated
scanning tools from picking up on filename patterns. As such it's an
intermediate between "off" and "standard". The advantage is that it
allows for longer path segment names.

There is a possibility with some unicode based filenames that the
obfuscation is weak and may map lower case characters to upper case
equivalents.  You can not rely on this for strong protection.

  * file names very lightly obfuscated
  * file names can be longer than standard encryption
  * can use sub paths and copy single files
  * directory structure visibile
  * identical files names will have identical uploaded names

Cloud storage systems have various limits on file name length and
total path length which you are more likely to hit using "Standard"
file name encryption.  If you keep your file names to below 156
characters in length then you should be OK on all providers.

There may be an even more secure file name encryption mode in the
future which will address the long file name problem.

### Modified time and hashes ###

Crypt stores modification times using the underlying remote so support
depends on that.

Hashes are not stored for crypt.  However the data integrity is
protected by an extremely strong crypto authenticator.

Note that you should use the `rclone cryptcheck` command to check the
integrity of a crypted remote instead of `rclone check` which can't
check the checksums properly.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --crypt-show-mapping ####

If this flag is set then for each file that the remote is asked to
list, it will log (at level INFO) a line stating the decrypted file
name and the encrypted file name.

This is so you can work out which encrypted names are which decrypted
names just in case you need to do something with the encrypted file
names, or for debugging purposes.

## Backing up a crypted remote ##

If you wish to backup a crypted remote, it it recommended that you use
`rclone sync` on the encrypted files, and make sure the passwords are
the same in the new encrypted remote.

This will have the following advantages

  * `rclone sync` will check the checksums while copying
  * you can use `rclone check` between the encrypted remotes
  * you don't decrypt and encrypt unecessarily

For example, let's say you have your original remote at `remote:` with
the encrypted version at `eremote:` with path `remote:crypt`.  You
would then set up the new remote `remote2:` and then the encrypted
version `eremote2:` with path `remote2:crypt` using the same passwords
as `eremote:`.

To sync the two remotes you would do

    rclone sync remote:crypt remote2:crypt

And to check the integrity you would do

    rclone check remote:crypt remote2:crypt

## File formats ##

### File encryption ###

Files are encrypted 1:1 source file to destination object.  The file
has a header and is divided into chunks.

#### Header ####

  * 8 bytes magic string `RCLONE\x00\x00`
  * 24 bytes Nonce (IV)

The initial nonce is generated from the operating systems crypto
strong random number genrator.  The nonce is incremented for each
chunk read making sure each nonce is unique for each block written.
The chance of a nonce being re-used is miniscule.  If you wrote an
exabyte of data (10¹⁸ bytes) you would have a probability of
approximately 2×10⁻³² of re-using a nonce.

#### Chunk ####

Each chunk will contain 64kB of data, except for the last one which
may have less data.  The data chunk is in standard NACL secretbox
format. Secretbox uses XSalsa20 and Poly1305 to encrypt and
authenticate messages.

Each chunk contains:

  * 16 Bytes of Poly1305 authenticator
  * 1 - 65536 bytes XSalsa20 encrypted data

64k chunk size was chosen as the best performing chunk size (the
authenticator takes too much time below this and the performance drops
off due to cache effects above this).  Note that these chunks are
buffered in memory so they can't be too big.

This uses a 32 byte (256 bit key) key derived from the user password.

#### Examples ####

1 byte file will encrypt to

  * 32 bytes header
  * 17 bytes data chunk

49 bytes total

1MB (1048576 bytes) file will encrypt to

  * 32 bytes header
  * 16 chunks of 65568 bytes

1049120 bytes total (a 0.05% overhead).  This is the overhead for big
files.

### Name encryption ###

File names are encrypted segment by segment - the path is broken up
into `/` separated strings and these are encrypted individually.

File segments are padded using using PKCS#7 to a multiple of 16 bytes
before encryption.

They are then encrypted with EME using AES with 256 bit key. EME
(ECB-Mix-ECB) is a wide-block encryption mode presented in the 2003
paper "A Parallelizable Enciphering Mode" by Halevi and Rogaway.

This makes for determinstic encryption which is what we want - the
same filename must encrypt to the same thing otherwise we can't find
it on the cloud storage system.

This means that

  * filenames with the same name will encrypt the same
  * filenames which start the same won't have a common prefix

This uses a 32 byte key (256 bits) and a 16 byte (128 bits) IV both of
which are derived from the user password.

After encryption they are written out using a modified version of
standard `base32` encoding as described in RFC4648.  The standard
encoding is modified in two ways:

  * it becomes lower case (no-one likes upper case filenames!)
  * we strip the padding character `=`

`base32` is used rather than the more efficient `base64` so rclone can be
used on case insensitive remotes (eg Windows, Amazon Drive).

### Key derivation ###

Rclone uses `scrypt` with parameters `N=16384, r=8, p=1` with a an
optional user supplied salt (password2) to derive the 32+32+16 = 80
bytes of key material required.  If the user doesn't supply a salt
then rclone uses an internal one.

`scrypt` makes it impractical to mount a dictionary attack on rclone
encrypted data.  For full protection agains this you should always use
a salt.

Dropbox
---------------------------------

Paths are specified as `remote:path`

Dropbox paths may be as deep as required, eg
`remote:directory/subdirectory`.

The initial setup for dropbox involves getting a token from Dropbox
which you need to do in your browser.  `rclone config` walks you

Here is an example of how to make a remote called `remote`.  First run:

     rclone config

This will guide you through an interactive setup process:

```

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote

```

You can then use it like this,

List directories in top level of your dropbox

    rclone lsd remote:

List all the files in your dropbox

    rclone ls remote:

To copy a local directory to a dropbox directory called backup

    rclone copy /home/source remote:backup

### Modified time and Hashes ###

Dropbox supports modified times, but the only way to set a
modification time is to re-upload the file.

This means that if you uploaded your data with an older version of
rclone which didn't support the v2 API and modified times, rclone will
decide to upload all your old data to fix the modification times.  If
you don't want this to happen use `--size-only` or `--checksum` flag
to stop it.

Dropbox supports [its own hash
type](https://www.dropbox.com/developers/reference/content-hash) which
is checked for all transfers.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --dropbox-chunk-size=SIZE ####

Upload chunk size. Max 150M. The default is 128MB.  Note that this
isn't buffered into memory.

### Limitations ###

Note that Dropbox is case insensitive so you can't have a file called
"Hello.doc" and one called "hello.doc".

There are some file names such as `thumbs.db` which Dropbox can't
store.  There is a full list of them in the ["Ignored Files" section
of this document](https://www.dropbox.com/en/help/145).  Rclone will
issue an error message `File name disallowed - not uploading` if it
attempt to upload one of those file names, but the sync won't fail.

If you have more than 10,000 files in a directory then `rclone purge
dropbox:dir` will return the error `Failed to purge: There are too
many files involved in this operation`.  As a work-around do an
`rclone delete dropbox:dir` followed by an `rclone rmdir dropbox:dir`.

FTP
------------------------------

FTP is the File Transfer Protocol. FTP support is provided using the
[github.com/jlaffaye/ftp](https://godoc.org/github.com/jlaffaye/ftp)
package.

Here is an example of making an FTP configuration.  First run

    rclone config

This will guide you through an interactive setup process. An FTP remote only
needs a host together with and a username and a password. With anonymous FTP
server, you will need to use `anonymous` as username and your email address as
the password.

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

This remote is called `remote` and can now be used like this

See all directories in the home directory

    rclone lsd remote:

Make a new directory

    rclone mkdir remote:path/to/directory

List the contents of a directory

    rclone ls remote:path/to/directory

Sync `/home/local/directory` to the remote directory, deleting any
excess files in the directory.

    rclone sync /home/local/directory remote:directory

### Modified time ###

FTP does not support modified times.  Any times you see on the server
will be time of upload.

### Checksums ###

FTP does not support any checksums.

### Limitations ###

Note that since FTP isn't HTTP based the following flags don't work
with it: `--dump-headers`, `--dump-bodies`, `--dump-auth`

Note that `--timeout` isn't supported (but `--contimeout` is).

Note that `--bind` isn't supported.

FTP could support server side move but doesn't yet.

Google Cloud Storage
-------------------------------------------------

Paths are specified as `remote:bucket` (or `remote:` for the `lsd`
command.)  You may put subdirectories in too, eg `remote:bucket/path/to/dir`.

The initial setup for google cloud storage involves getting a token from Google Cloud Storage
which you need to do in your browser.  `rclone config` walks you
through it.

Here is an example of how to make a remote called `remote`.  First run:

     rclone config

This will guide you through an interactive setup process:

Note that rclone runs a webserver on your local machine to collect the
token as returned from Google if you use auto config mode. This only
runs from the moment it opens your browser to the moment you get back
the verification code.  This is on `http://127.0.0.1:53682/` and this
it may require you to unblock it temporarily if you are running a host
firewall, or use manual mode.

This remote is called `remote` and can now be used like this

See all the buckets in your project

    rclone lsd remote:

Make a new bucket

    rclone mkdir remote:bucket

List the contents of a bucket

    rclone ls remote:bucket

Sync `/home/local/directory` to the remote bucket, deleting any excess
files in the bucket.

    rclone sync /home/local/directory remote:bucket

### Service Account support ###

You can set up rclone with Google Cloud Storage in an unattended mode,
i.e. not tied to a specific end-user Google account. This is useful
when you want to synchronise files onto machines that don't have
actively logged-in users, for example build machines.

To get credentials for Google Cloud Platform
[IAM Service Accounts](https://cloud.google.com/iam/docs/service-accounts),
please head to the
[Service Account](https://console.cloud.google.com/permissions/serviceaccounts)
section of the Google Developer Console. Service Accounts behave just
like normal `User` permissions in
[Google Cloud Storage ACLs](https://cloud.google.com/storage/docs/access-control),
so you can limit their access (e.g. make them read only). After
creating an account, a JSON file containing the Service Account's
credentials will be downloaded onto your machines. These credentials
are what rclone will use for authentication.

To use a Service Account instead of OAuth2 token flow, enter the path
to your Service Account credentials at the `service_account_file`
prompt and rclone won't use the browser based authentication
flow.

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Modified time ###

Google google cloud storage stores md5sums natively and rclone stores
modification times as metadata on the object, under the "mtime" key in
RFC3339 format accurate to 1ns.

Google Drive
-----------------------------------------

Paths are specified as `drive:path`

Drive paths may be as deep as required, eg `drive:directory/subdirectory`.

The initial setup for drive involves getting a token from Google drive
which you need to do in your browser.  `rclone config` walks you
through it.

Here is an example of how to make a remote called `remote`.  First run:

     rclone config

This will guide you through an interactive setup process:

Note that rclone runs a webserver on your local machine to collect the

runs from the moment it opens your browser to the moment you get back
the verification code.  This is on `http://127.0.0.1:53682/` and this
it may require you to unblock it temporarily if you are running a host
firewall, or use manual mode.

You can then use it like this,

List directories in top level of your drive

    rclone lsd remote:

List all the files in your drive

    rclone ls remote:

To copy a local directory to a drive directory called backup

    rclone copy /home/source remote:backup

### Team drives ###

If you want to configure the remote to point to a Google Team Drive
then answer `y` to the question `Configure this as a team drive?`.

This will fetch the list of Team Drives from google and allow you to
configure which one you want to use.  You can also type in a team
drive ID if you prefer.

For example:

```
Configure this as a team drive?
y) Yes
n) No
y/n> y

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

### Modified time ###

Google drive stores modification times accurate to 1 ms.

### Revisions ###

Google drive stores revisions of files.  When you upload a change to
an existing file to google drive using rclone it will create a new
revision of that file.

Revisions follow the standard google policy which at time of writing
was

  * They are deleted after 30 days or 100 revisions (whatever comes first).
  * They do not count towards a user storage quota.

### Deleting files ###

By default rclone will send all files to the trash when deleting
files.  If deleting them permanently is required then use the
`--drive-use-trash=false` flag, or set the equivalent environment
variable.

### Emptying trash ###

If you wish to empty your trash you can use the `rclone cleanup remote:`
command which will permanently delete all your trashed files. This command
does not take any path arguments.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --drive-auth-owner-only ####

Only consider files owned by the authenticated user.

#### --drive-chunk-size=SIZE ####

Upload chunk size. Must a power of 2 >= 256k. Default value is 8 MB.

Making this larger will improve performance, but note that each chunk
is buffered in memory one per transfer.

Reducing this will reduce memory usage but decrease performance.

#### --drive-formats ####

Google documents can only be exported from Google drive.  When rclone
downloads a Google doc it chooses a format to download depending upon
this setting.

By default the formats are `docx,xlsx,pptx,svg` which are a sensible
default for an editable document.

When choosing a format, rclone runs down the list provided in order
and chooses the first file format the doc can be exported as from the
list. If the file can't be exported to a format on the formats list,
then rclone will choose a format from the default list.

If you prefer an archive copy then you might use `--drive-formats
pdf`, or if you prefer openoffice/libreoffice formats you might use
`--drive-formats ods,odt,odp`.

Note that rclone adds the extension to the google doc, so if it is
calles `My Spreadsheet` on google docs, it will be exported as `My
Spreadsheet.xlsx` or `My Spreadsheet.pdf` etc.

Here are the possible extensions with their corresponding mime types.

| Extension | Mime Type | Description |
| --------- |-----------| ------------|
| csv  | text/csv | Standard CSV format for Spreadsheets |
| doc  | application/msword | Micosoft Office Document |
| docx | application/vnd.openxmlformats-officedocument.wordprocessingml.document | Microsoft Office Document |
| epub | application/epub+zip | E-book format |
| html | text/html | An HTML Document |
| jpg  | image/jpeg | A JPEG Image File |
| odp  | application/vnd.oasis.opendocument.presentation | Openoffice Presentation |
| ods  | application/vnd.oasis.opendocument.spreadsheet | Openoffice Spreadsheet |
| ods  | application/x-vnd.oasis.opendocument.spreadsheet | Openoffice Spreadsheet |
| odt  | application/vnd.oasis.opendocument.text | Openoffice Document |
| pdf  | application/pdf | Adobe PDF Format |
| png  | image/png | PNG Image Format|
| pptx | application/vnd.openxmlformats-officedocument.presentationml.presentation | Microsoft Office Powerpoint |
| rtf  | application/rtf | Rich Text Format |
| svg  | image/svg+xml | Scalable Vector Graphics Format |
| tsv  | text/tab-separated-values | Standard TSV format for spreadsheets |
| txt  | text/plain | Plain Text |
| xls  | application/vnd.ms-excel | Microsoft Office Spreadsheet |
| xlsx | application/vnd.openxmlformats-officedocument.spreadsheetml.sheet | Microsoft Office Spreadsheet |
| zip  | application/zip | A ZIP file of HTML, Images CSS |

#### --drive-list-chunk int ####

Size of listing chunk 100-1000. 0 to disable. (default 1000)

#### --drive-shared-with-me ####

Only show files that are shared with me

#### --drive-skip-gdocs ####

Skip google documents in all listings. If given, gdocs practically become invisible to rclone.

#### --drive-trashed-only ####

Only show files that are in the trash.  This will show trashed files
in their original directory structure.

#### --drive-upload-cutoff=SIZE ####

File size cutoff for switching to chunked upload.  Default is 8 MB.

#### --drive-use-trash ####

Controls whether files are sent to the trash or deleted
permanently. Defaults to true, namely sending files to the trash.  Use
`--drive-use-trash=false` to delete files permanently instead.

### Limitations ###

Drive has quite a lot of rate limiting.  This causes rclone to be
limited to transferring about 2 files per second only.  Individual
files may be transferred much faster at 100s of MBytes/s but lots of
small files can take a long time.

Server side copies are also subject to a separate rate limit. If you
see User rate limit exceeded errors, wait at least 24 hours and retry.
You can disable server side copies with `--disable copy` to download
and upload the files if you prefer.

### Duplicated files ###

Sometimes, for no reason I've been able to track down, drive will
duplicate a file that rclone uploads.  Drive unlike all the other
remotes can have duplicated files.

Duplicated files cause problems with the syncing and you will see
messages in the log about duplicates.

Use `rclone dedupe` to fix duplicated files.

Note that this isn't just a problem with rclone, even Google Photos on
Android duplicates files on drive sometimes.

### Rclone appears to be re-copying files it shouldn't ###

There are two possible reasons for rclone to recopy files which
haven't changed to Google Drive.

The first is the duplicated file issue above - run `rclone dedupe` and
check your logs for duplicate object or directory messages.

The second is that sometimes Google reports different sizes for the
Google Docs exports which will cause rclone to re-download Google Docs
for no apparent reason.  `--ignore-size` is a not very satisfactory
work-around for this if it is causing you a lot of problems.

### Google docs downloads sometimes fail with "Failed to copy: read X bytes expecting Y" ###

This is the same problem as above.  Google reports the google doc is
one size, but rclone downloads a different size.  Work-around with the
`--ignore-size` flag or wait for rclone to retry the download which it
will.

### Making your own client_id ###

When you use rclone with Google drive in its default configuration you
are using rclone's client_id.  This is shared between all the rclone
users.  There is a global rate limit on the number of queries per
second that each client_id can do set by Google.  rclone already has a
high quota and I will continue to make sure it is high enough by
contacting Google.

However you might find you get better performance making your own
client_id if you are a heavy user. Or you may not depending on exactly
how Google have been raising rclone's rate limit.

Here is how to create your own Google Drive client ID for rclone:

1. Log into the [Google API
Console](https://console.developers.google.com/) with your Google
account. It doesn't matter what Google account you use. (It need not
be the same account as the Google Drive you want to access)

2. Select a project or create a new project.

3. Under Overview, Google APIs, Google Apps APIs, click "Drive API",
then "Enable".

4. Click "Credentials" in the left-side panel (not "Go to
credentials", which opens the wizard), then "Create credentials", then
"OAuth client ID".  It will prompt you to set the OAuth consent screen
product name, if you haven't set one already.

5. Choose an application type of "other", and click "Create". (the
default name is fine)

6. It will show you a client ID and client secret.  Use these values
in rclone config to add a new remote or edit an existing remote.

(Thanks to @balazer on github for these instructions.)

HTTP
-------------------------------------------------

The HTTP remote is a read only remote for reading files of a
webserver.  The webserver should provide file listings which rclone
will read and turn into a remote.  This has been tested with common
webservers such as Apache/Nginx/Caddy and will likely work with file
listings from most web servers.  (If it doesn't then please file an
issue, or send a pull request!)

Paths are specified as `remote:` or `remote:path/to/dir`.

Here is an example of how to make a remote called `remote`.  First
run:

     rclone config

This will guide you through an interactive setup process:

This remote is called `remote` and can now be used like this

See all the top level directories

    rclone lsd remote:

List the contents of a directory

    rclone ls remote:directory

Sync the remote `directory` to `/home/local/directory`, deleting any excess files.

    rclone sync remote:directory /home/local/directory

### Read only ###

This remote is read only - you can't upload files to an HTTP server.

### Modified time ###

Most HTTP servers store time accurate to 1 second.

### Checksum ###

No checksums are stored.

### Usage without a config file ###

Note that since only two environment variable need to be set, it is
easy to use without a config file like this.

```
RCLONE_CONFIG_ZZ_TYPE=http RCLONE_CONFIG_ZZ_URL=https://beta.rclone.org rclone lsd zz:
```

Or if you prefer

```
export RCLONE_CONFIG_ZZ_TYPE=http
export RCLONE_CONFIG_ZZ_URL=https://beta.rclone.org
rclone lsd zz:
```

Hubic
-----------------------------------------

Paths are specified as `remote:path`

Paths are specified as `remote:container` (or `remote:` for the `lsd`
command.)  You may put subdirectories in too, eg `remote:container/path/to/dir`.

The initial setup for Hubic involves getting a token from Hubic which
you need to do in your browser.  `rclone config` walks you through it.

Here is an example of how to make a remote called `remote`.  First run:

     rclone config

This will guide you through an interactive setup process:

d) Delete this remote
y/e/d> y
```

See the [remote setup docs](https://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the
token as returned from Hubic. This only runs from the moment it opens
your browser to the moment you get back the verification code.  This
is on `http://127.0.0.1:53682/` and this it may require you to unblock
it temporarily if you are running a host firewall.

Once configured you can then use `rclone` like this,

List containers in the top level of your Hubic

    rclone lsd remote:

List all the files in your Hubic

    rclone ls remote:

To copy a local directory to an Hubic directory called backup

    rclone copy /home/source remote:backup

If you want the directory to be visible in the official *Hubic
browser*, you need to copy your files to the `default` directory

    rclone copy /home/source remote:default/backup

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Modified time ###

The modified time is stored as metadata on the object as
`X-Object-Meta-Mtime` as floating point since the epoch accurate to 1
ns.

This is a defacto standard (used in the official python-swiftclient
amongst others) for storing the modification time for an object.

Note that Hubic wraps the Swift backend, so most of the properties of
are the same.

### Limitations ###

This uses the normal OpenStack Swift mechanism to refresh the Swift
API credentials and ignores the expires field returned by the Hubic
API.

The Swift API doesn't return a correct MD5SUM for segmented files
(Dynamic or Static Large Objects) so rclone won't check or use the
MD5SUM for these.

Microsoft Azure Blob Storage
-----------------------------------------

Paths are specified as `remote:container` (or `remote:` for the `lsd`
command.)  You may put subdirectories in too, eg
`remote:container/path/to/dir`.

Here is an example of making a Microsoft Azure Blob Storage
configuration.  For a remote called `remote`.  First run:

See all containers

    rclone lsd remote:

Make a new container

    rclone mkdir remote:container

List the contents of a container

    rclone ls remote:container

Sync `/home/local/directory` to the remote container, deleting any excess
files in the container.

    rclone sync /home/local/directory remote:container

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Modified time ###

The modified time is stored as metadata on the object with the `mtime`
key.  It is stored using RFC3339 Format time with nanosecond
precision.  The metadata is supplied during directory listings so
there is no overhead to using it.

### Hashes ###

MD5 hashes are stored with blobs.  However blobs that were uploaded in
chunks only have an MD5 if the source remote was capable of MD5
hashes, eg the local disk.

### Multipart uploads ###

Rclone supports multipart uploads with Azure Blob storage.  Files
bigger than 256MB will be uploaded using chunked upload by default.

The files will be uploaded in parallel in 4MB chunks (by default).
Note that these chunks are buffered in memory and there may be up to
`--transfers` of them being uploaded at once.

Files can't be split into more than 50,000 chunks so by default, so
the largest file that can be uploaded with 4MB chunk size is 195GB.
Above this rclone will double the chunk size until it creates less
than 50,000 chunks.  By default this will mean a maximum file size of
3.2TB can be uploaded.  This can be raised to 5TB using
`--azureblob-chunk-size 100M`.

Note that rclone doesn't commit the block list until the end of the
upload which means that there is a limit of 9.5TB of multipart uploads
in progress as Azure won't allow more than that amount of uncommitted
blocks.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --azureblob-upload-cutoff=SIZE ####

Cutoff for switching to chunked upload - must be <= 256MB. The default
is 256MB.

#### --azureblob-chunk-size=SIZE ####

Upload chunk size.  Default 4MB.  Note that this is stored in memory
and there may be up to `--transfers` chunks stored at once in memory.
This can be at most 100MB.

### Limitations ###

MD5 sums are only uploaded with chunked files if the source has an MD5
sum.  This will always be the case for a local to azure copy.

Microsoft OneDrive
-----------------------------------------

Paths are specified as `remote:path`

Paths may be as deep as required, eg `remote:directory/subdirectory`.

The initial setup for OneDrive involves getting a token from
Microsoft which you need to do in your browser.  `rclone config` walks
you through it.

Here is an example of how to make a remote called `remote`.  First run:

     rclone config

This will guide you through an interactive setup process:

```

See the [remote setup docs](https://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the
token as returned from Microsoft. This only runs from the moment it
opens your browser to the moment you get back the verification
code.  This is on `http://127.0.0.1:53682/` and this it may require
you to unblock it temporarily if you are running a host firewall.

Once configured you can then use `rclone` like this,

List directories in top level of your OneDrive

    rclone lsd remote:

List all the files in your OneDrive

    rclone ls remote:

To copy a local directory to an OneDrive directory called backup

    rclone copy /home/source remote:backup

### OneDrive for Business ###

There is additional support for OneDrive for Business.
Select "b" when ask
```
Choose OneDrive account type?
 * Say b for a OneDrive business account
 * Say p for a personal OneDrive account
b) Business
p) Personal
b/p> 
```
After that rclone requires an authentication of your account. The application will first authenticate your account, then query the OneDrive resource URL
and do a second (silent) authentication for this resource URL. 

### Modified time and hashes ###

OneDrive allows modification times to be set on objects accurate to 1
second.  These will be used to detect whether objects need syncing or
not.

One drive supports SHA1 type hashes, so you can use `--checksum` flag.


### Deleting files ###

Any files you delete with rclone will end up in the trash.  Microsoft
doesn't provide an API to permanently delete files, nor to empty the
trash, so you will have to do that with one of Microsoft's apps or via
the OneDrive website.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --onedrive-chunk-size=SIZE ####

Above this size files will be chunked - must be multiple of 320k. The
default is 10MB.  Note that the chunks will be buffered into memory.

#### --onedrive-upload-cutoff=SIZE ####

Cutoff for switching to chunked upload - must be <= 100MB. The default
is 10MB.

### Limitations ###

Note that OneDrive is case insensitive so you can't have a
file called "Hello.doc" and one called "hello.doc".

There are quite a few characters that can't be in OneDrive file
names.  These can't occur on Windows platforms, but on non-Windows
platforms they are common.  Rclone will map these names to and from an
identical looking unicode equivalent.  For example if a file has a `?`
in it will be mapped to `？` instead.

The largest allowed file size is 10GiB (10,737,418,240 bytes).

QingStor
---------------------------------------

Paths are specified as `remote:bucket` (or `remote:` for the `lsd`
command.)  You may put subdirectories in too, eg `remote:bucket/path/to/dir`.

Here is an example of making an QingStor configuration.  First run

    rclone config

This will guide you through an interactive setup process.

This remote is called `remote` and can now be used like this

See all buckets

    rclone lsd remote:

Make a new bucket

    rclone mkdir remote:bucket

List the contents of a bucket

    rclone ls remote:bucket

Sync `/home/local/directory` to the remote bucket, deleting any excess
files in the bucket.

    rclone sync /home/local/directory remote:bucket

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Multipart uploads ###

rclone supports multipart uploads with QingStor which means that it can
upload files bigger than 5GB. Note that files uploaded with multipart
upload don't have an MD5SUM.

### Buckets and Zone ###

With QingStor you can list buckets (`rclone lsd`) using any zone,
but you can only access the content of a bucket from the zone it was
created in.  If you attempt to access a bucket from the wrong zone,
you will get an error, `incorrect zone, the bucket is not in 'XXX'
zone`.

### Authentication ###

There are two ways to supply `rclone` with a set of QingStor
credentials. In order of precedence:

 - Directly in the rclone configuration file (as configured by `rclone config`)
   - set `access_key_id` and `secret_access_key`
 - Runtime configuration:
   - set `env_auth` to `true` in the config file
   - Exporting the following environment variables before running `rclone`
     - Access Key ID: `QS_ACCESS_KEY_ID` or `QS_ACCESS_KEY`
     - Secret Access Key: `QS_SECRET_ACCESS_KEY` or `QS_SECRET_KEY`

Swift
----------------------------------------

Swift refers to [Openstack Object Storage](https://docs.openstack.org/swift/latest/).
Commercial implementations of that being:

  * [Rackspace Cloud Files](https://www.rackspace.com/cloud/files/)
  * [Memset Memstore](https://www.memset.com/cloud/storage/)
  * [OVH Object Storage](https://www.ovh.co.uk/public-cloud/storage/object-storage/)
  * [Oracle Cloud Storage](https://cloud.oracle.com/storage-opc)

Paths are specified as `remote:container` (or `remote:` for the `lsd`
command.)  You may put subdirectories in too, eg `remote:container/path/to/dir`.

This remote is called `remote` and can now be used like this

See all containers

    rclone lsd remote:

Make a new container

    rclone mkdir remote:container

List the contents of a container

    rclone ls remote:container

Sync `/home/local/directory` to the remote container, deleting any
excess files in the container.

    rclone sync /home/local/directory remote:container

### Configuration from an Openstack credentials file ###

An Opentstack credentials file typically looks something something
like this (without the comments)

```
export OS_AUTH_URL=https://a.provider.net/v2.0
export OS_TENANT_ID=ffffffffffffffffffffffffffffffff
export OS_TENANT_NAME="1234567890123456"
export OS_USERNAME="123abc567xy"
echo "Please enter your OpenStack Password: "
read -sr OS_PASSWORD_INPUT
export OS_PASSWORD=$OS_PASSWORD_INPUT
export OS_REGION_NAME="SBG1"
if [ -z "$OS_REGION_NAME" ]; then unset OS_REGION_NAME; fi
```

The config file needs to look something like this where `$OS_USERNAME`
represents the value of the `OS_USERNAME` variable - `123abc567xy` in
the example above.

```
[remote]
type = swift
user = $OS_USERNAME
key = $OS_PASSWORD
auth = $OS_AUTH_URL
tenant = $OS_TENANT_NAME
```

Note that you may (or may not) need to set `region` too - try without first.

### Configuration from the environment ###

If you prefer you can configure rclone to use swift using a standard
set of OpenStack environment variables.

When you run through the config, make sure you choose `true` for
`env_auth` and leave everything else blank.

rclone will then set any empty config parameters from the enviroment
using standard OpenStack environment variables.  There is [a list of
the
variables](https://godoc.org/github.com/ncw/swift#Connection.ApplyEnvironment)
in the docs for the swift library.

#### Using rclone without a config file ####

You can use rclone with swift without a config file, if desired, like
this:

```
source openstack-credentials-file
export RCLONE_CONFIG_MYREMOTE_TYPE=swift
export RCLONE_CONFIG_MYREMOTE_ENV_AUTH=true
rclone lsd myremote:
```

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Specific options ###

Here are the command line options specific to this cloud storage
system.

#### --swift-chunk-size=SIZE ####

Above this size files will be chunked into a _segments container.  The
default for this is 5GB which is its maximum value.

### Modified time ###

The modified time is stored as metadata on the object as
`X-Object-Meta-Mtime` as floating point since the epoch accurate to 1
ns.

This is a defacto standard (used in the official python-swiftclient
amongst others) for storing the modification time for an object.

### Limitations ###

The Swift API doesn't return a correct MD5SUM for segmented files
(Dynamic or Static Large Objects) so rclone won't check or use the
MD5SUM for these.

### Troubleshooting ###

#### Rclone gives Failed to create file system for "remote:": Bad Request ####

Due to an oddity of the underlying swift library, it gives a "Bad
Request" error rather than a more sensible error when the
authentication fails for Swift.

So this most likely means your username / password is wrong.  You can
investigate further with the `--dump-bodies` flag.

This may also be caused by specifying the region when you shouldn't
have (eg OVH).

#### Rclone gives Failed to create file system: Response didn't have storage storage url and auth token ####

This is most likely caused by forgetting to specify your tenant when
setting up a swift remote.

SFTP is the [Secure (or SSH) File Transfer
Protocol](https://en.wikipedia.org/wiki/SSH_File_Transfer_Protocol).

It runs over SSH v2 and is standard with most modern SSH
installations.

Paths are specified as `remote:path`. If the path does not begin with
a `/` it is relative to the home directory of the user.  An empty path
`remote:` refers to the users home directory.

Here is an example of making a SFTP configuration.  First run

    rclone config

This will guide you through an interactive setup process.

user = sftpuser
port = 
pass = 
key_file = 
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

This remote is called `remote` and can now be used like this

See all directories in the home directory

    rclone lsd remote:

Make a new directory

    rclone mkdir remote:path/to/directory

List the contents of a directory

    rclone ls remote:path/to/directory

Sync `/home/local/directory` to the remote directory, deleting any
excess files in the directory.

    rclone sync /home/local/directory remote:directory

### SSH Authentication ###

The SFTP remote supports 3 authentication methods

  * Password
  * Key file
  * ssh-agent

Key files should be unencrypted PEM-encoded private key files.  For
instance `/home/$USER/.ssh/id_rsa`.

If you don't specify `pass` or `key_file` then it will attempt to
contact an ssh-agent.

### ssh-agent on macOS ###

Note that there seem to be various problems with using an ssh-agent on
macOS due to recent changes in the OS.  The most effective work-around
seems to be to start an ssh-agent in each session, eg

    eval `ssh-agent -s` && ssh-add -A

And then at the end of the session

    eval `ssh-agent -k`

These commands can be used in scripts of course.

### Modified time ###

Modified times are stored on the server to 1 second precision.

Modified times are used in syncing and are fully supported.

### Limitations ###

SFTP supports checksums if the same login has shell access and `md5sum`
or `sha1sum` as well as `echo` are in the remote's PATH.

The only ssh agent supported under Windows is Putty's pagent.

SFTP isn't supported under plan9 until [this
issue](https://github.com/pkg/sftp/issues/156) is fixed.

Note that since SFTP isn't HTTP based the following flags don't work
with it: `--dump-headers`, `--dump-bodies`, `--dump-auth`

Note that `--timeout` isn't supported (but `--contimeout` is).

Yandex Disk
----------------------------------------

[Yandex Disk](https://disk.yandex.com) is a cloud storage solution created by [Yandex](https://yandex.com).

Yandex paths may be as deep as required, eg `remote:directory/subdirectory`.

Here is an example of making a yandex configuration.  First run

    rclone config

This will guide you through an interactive setup process:

```
No remotes found - make a new one
n) New remote
s) Set configuration password
n/s> n

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```

See the [remote setup docs](https://rclone.org/remote_setup/) for how to set it up on a
machine with no Internet browser available.

Note that rclone runs a webserver on your local machine to collect the
token as returned from Yandex Disk. This only runs from the moment it
opens your browser to the moment you get back the verification code.
This is on `http://127.0.0.1:53682/` and this it may require you to
unblock it temporarily if you are running a host firewall.

Once configured you can then use `rclone` like this,

See top level directories

    rclone lsd remote:

Make a new directory

    rclone mkdir remote:directory

List the contents of a directory

    rclone ls remote:directory

Sync `/home/local/directory` to the remote path, deleting any
excess files in the path.

    rclone sync /home/local/directory remote:directory

### --fast-list ###

This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.

### Modified time ###

Modified times are supported and are stored accurate to 1 ns in custom
metadata called `rclone_modified` in RFC3339 with nanoseconds format.

### MD5 checksums ###

MD5 checksums are natively supported by Yandex Disk.

### Emptying Trash ###

If you wish to empty your trash you can use the `rclone cleanup remote:`
command which will permanently delete all your trashed files. This command
does not take any path arguments.

Local Filesystem
-------------------------------------------

Local paths are specified as normal filesystem paths, eg `/path/to/wherever`, so

    rclone sync /home/source /tmp/destination

Will sync `/home/source` to `/tmp/destination`

These can be configured into the config file for consistencies sake,
but it is probably easier not to.

### Modified time ###

Rclone reads and writes the modified time using an accuracy determined by
the OS.  Typically this is 1ns on Linux, 10 ns on Windows and 1 Second
on OS X.

### Filenames ###

Filenames are expected to be encoded in UTF-8 on disk.  This is the
normal case for Windows and OS X.

There is a bit more uncertainty in the Linux world, but new
distributions will have UTF-8 encoded files names. If you are using an
old Linux filesystem with non UTF-8 file names (eg latin1) then you
can use the `convmv` tool to convert the filesystem to UTF-8. This
tool is available in most distributions' package managers.

If an invalid (non-UTF8) filename is read, the invalid caracters will
be replaced with the unicode replacement character, '<27>'.  `rclone`
will emit a debug message in this case (use `-v` to see), eg

```
Local file system at .: Replacing invalid UTF-8 characters in "gro\xdf"
```

### Long paths on Windows ###

Rclone handles long paths automatically, by converting all paths to long
[UNC paths](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx#maxpath)
which allows paths up to 32,767 characters.

This is why you will see that your paths, for instance `c:\files` is
converted to the UNC path `\\?\c:\files` in the output,
and `\\server\share` is converted to `\\?\UNC\server\share`.

However, in rare cases this may cause problems with buggy file
system drivers like [EncFS](https://github.com/ncw/rclone/issues/261).
To disable UNC conversion globally, add this to your `.rclone.conf` file:

```
[local]
nounc = true
```

If you want to selectively disable UNC, you can add it to a separate entry like this:

```
[nounc]
type = local
nounc = true
```
And use rclone like this:

`rclone copy c:\src nounc:z:\dst`

This will use UNC paths on `c:\src` but not on `z:\dst`.
Of course this will cause problems if the absolute path length of a
file exceeds 258 characters on z, so only use this option if you have to.

### Specific options ###

Here are the command line options specific to local storage

#### --copy-links, -L ####

Normally rclone will ignore symlinks or junction points (which behave
like symlinks under Windows).

If you supply this flag then rclone will follow the symlink and copy
the pointed to file or directory.

This flag applies to all commands.

For example, supposing you have a directory structure like this

```
$ tree /tmp/a
/tmp/a
├── b -> ../b
├── expected -> ../expected
├── one
└── two
    └── three
```

Then you can see the difference with and without the flag like this

```
$ rclone ls /tmp/a
        6 one
        6 two/three
```

and

```
$ rclone -L ls /tmp/a
     4174 expected
        6 one
        6 two/three
        6 b/two
        6 b/one
```

#### --local-no-unicode-normalization ####

This flag is deprecated now.  Rclone no longer normalizes unicode file
names, but it compares them with unicode normalization in the sync
routine instead.

#### --one-file-system, -x ####

This tells rclone to stay in the filesystem specified by the root and
not to recurse into different file systems.

For example if you have a directory heirachy like this

```
root
├── disk1     - disk1 mounted on the root
│   └── file3 - stored on disk1
├── disk2     - disk2 mounted on the root
│   └── file4 - stored on disk12
├── file1     - stored on the root disk
└── file2     - stored on the root disk
```

Using `rclone --one-file-system copy root remote:` will only copy `file1` and `file2`.  Eg

```
$ rclone -q --one-file-system ls root
        0 file1
        0 file2
```

```
$ rclone -q ls root
        0 disk1/file3
        0 disk2/file4
        0 file1
        0 file2
```

**NB** Rclone (like most unix tools such as `du`, `rsync` and `tar`)
treats a bind mount to the same device as being on the same
filesystem.

**NB** This flag is only available on Unix based systems.  On systems
where it isn't supported (eg Windows) it will not appear as an valid
flag.

#### --skip-links ####

This flag disables warning messages on skipped symlinks or junction
points, as you explicitly acknowledge that they should be skipped.

Bugs and Limitations
--------------------

### Empty directories are left behind / not created ##

With remotes that have a concept of directory, eg Local and Drive,
empty directories may be left behind, or not created when one was
expected.

This is because rclone doesn't have a concept of a directory - it only
works on objects.  Most of the object storage systems can't actually
store a directory so there is nowhere for rclone to store anything
about directories.

You can work round this to some extent with the`purge` command which
will delete everything under the path, **inluding** empty directories.

This may be fixed at some point in
[Issue #100](https://github.com/ncw/rclone/issues/100)

### Directory timestamps aren't preserved ##

For the same reason as the above, rclone doesn't have a concept of a
directory - it only works on objects, therefore it can't preserve the
timestamps of directories.

Frequently Asked Questions
--------------------------

### Do all cloud storage systems support all rclone commands ###

Yes they do.  All the rclone commands (eg `sync`, `copy` etc) will
work on all the remote storage systems.

### Can I copy the config from one machine to another ###

Sure!  Rclone stores all of its config in a single file.  If you want
to find this file, the simplest way is to run `rclone -h` and look at
the help for the `--config` flag which will tell you where it is.

See the [remote setup docs](https://rclone.org/remote_setup/) for more info.

### How do I configure rclone on a remote / headless box with no browser? ###

This has now been documented in its own [remote setup page](https://rclone.org/remote_setup/).

### Can rclone sync directly from drive to s3 ###

Rclone can sync between two remote cloud storage systems just fine.

Note that it effectively downloads the file and uploads it again, so
the node running rclone would need to have lots of bandwidth.

The syncs would be incremental (on a file by file basis).

Eg

    rclone sync drive:Folder s3:bucket


### Using rclone from multiple locations at the same time ###

You can use rclone from multiple places at the same time if you choose
different subdirectory for the output, eg

```
Server A> rclone sync /tmp/whatever remote:ServerA
Server B> rclone sync /tmp/whatever remote:ServerB
```

If you sync to the same directory then you should use rclone copy
otherwise the two rclones may delete each others files, eg

```
Server A> rclone copy /tmp/whatever remote:Backup
Server B> rclone copy /tmp/whatever remote:Backup
```

The file names you upload from Server A and Server B should be
different in this case, otherwise some file systems (eg Drive) may
make duplicates.

### Why doesn't rclone support partial transfers / binary diffs like rsync? ###

Rclone stores each file you transfer as a native object on the remote
cloud storage system.  This means that you can see the files you
upload as expected using alternative access methods (eg using the
Google Drive web interface).  There is a 1:1 mapping between files on
your hard disk and objects created in the cloud storage system.

Cloud storage systems (at least none I've come across yet) don't
support partially uploading an object. You can't take an existing
object, and change some bytes in the middle of it.

It would be possible to make a sync system which stored binary diffs
instead of whole objects like rclone does, but that would break the
1:1 mapping of files on your hard disk to objects in the remote cloud
storage system.

All the cloud storage systems support partial downloads of content, so
it would be possible to make partial downloads work.  However to make
this work efficiently this would require storing a significant amount
of metadata, which breaks the desired 1:1 mapping of files to objects.

### Can rclone do bi-directional sync? ###

No, not at present.  rclone only does uni-directional sync from A ->
B. It may do in the future though since it has all the primitives - it
just requires writing the algorithm to do it.

### Can I use rclone with an HTTP proxy? ###

Yes. rclone will use the environment variables `HTTP_PROXY`,
`HTTPS_PROXY` and `NO_PROXY`, similar to cURL and other programs.

`HTTPS_PROXY` takes precedence over `HTTP_PROXY` for https requests.

The environment values may be either a complete URL or a "host[:port]",
in which case the "http" scheme is assumed.

The `NO_PROXY` allows you to disable the proxy for specific hosts.
Hosts must be comma separated, and can contain domains or parts.
For instance "foo.com" also matches "bar.foo.com".

### Rclone gives x509: failed to load system roots and no roots provided error ###

This means that `rclone` can't file the SSL root certificates.  Likely
you are running `rclone` on a NAS with a cut-down Linux OS, or
possibly on Solaris.

Rclone (via the Go runtime) tries to load the root certificates from
these places on Linux.

    "/etc/ssl/certs/ca-certificates.crt", // Debian/Ubuntu/Gentoo etc.
    "/etc/pki/tls/certs/ca-bundle.crt",   // Fedora/RHEL
    "/etc/ssl/ca-bundle.pem",             // OpenSUSE
    "/etc/pki/tls/cacert.pem",            // OpenELEC

So doing something like this should fix the problem.  It also sets the
time which is important for SSL to work properly.

```
mkdir -p /etc/ssl/certs/
curl -o /etc/ssl/certs/ca-certificates.crt https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt
ntpclient -s -h pool.ntp.org
```

Note that you may need to add the `--insecure` option to the `curl` command line if it doesn't work without.

```
curl --insecure -o /etc/ssl/certs/ca-certificates.crt https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt
```

### Rclone gives Failed to load config file: function not implemented error ###

Likely this means that you are running rclone on Linux version not
supported by the go runtime, ie earlier than version 2.6.23.

See the [system requirements section in the go install
docs](https://golang.org/doc/install) for full details.

### All my uploaded docx/xlsx/pptx files appear as archive/zip ###

This is caused by uploading these files from a Windows computer which
hasn't got the Microsoft Office suite installed.  The easiest way to
fix is to install the Word viewer and the Microsoft Office
Compatibility Pack for Word, Excel, and PowerPoint 2007 and later
versions' file formats

### tcp lookup some.domain.com no such host ###

This happens when rclone cannot resolve a domain. Please check that
your DNS setup is generally working, e.g.

```
# both should print a long list of possible IP addresses
dig www.googleapis.com          # resolve using your default DNS
dig www.googleapis.com @8.8.8.8 # resolve with Google's DNS server
```

If you are using `systemd-resolved` (default on Arch Linux), ensure it
is at version 233 or higher. Previous releases contain a bug which
causes not all domains to be resolved properly.
