Install
-------
Rclone is a Go program and comes as a single binary file.
[Download](http://rclone.org/downloads/) the relevant binary.
Or alternatively if you have Go installed use
go get 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 (remove `-f` if using go < 1.4)
go get -u -v -f github.com/ncw/rclone/...
See the [Usage section](http://rclone.org/docs/) of the docs for how to use rclone, or
run `rclone -h`.
linux binary downloaded files install example
-------
unzip rclone-v1.17-linux-amd64.zip
cd rclone-v1.17-linux-amd64
#copy binary file
sudo cp rclone /usr/sbin/
sudo chown root:root /usr/sbin/rclone
sudo chmod 755 /usr/sbin/rclone
#install manpage
sudo mkdir -p /usr/local/share/man/man1
sudo cp rclone.1 /usr/local/share/man/man1/
sudo mandb
Configure
---------
First you'll need to configure rclone. As the object storage systems
have quite complicated authentication these are kept in a config file
`.rclone.conf` in your home directory by default. (You can use the
`--config` option to choose a different config file.)
The easiest way to make the config is to run rclone with the config
option:
rclone config
See the following for detailed instructions for

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 copy source:path dest:path ###
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.
### rclone sync source:path dest:path ###
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 ls remote:path ###
List all the objects in the the path with size and path.
### rclone lsd remote:path ###
List all directories/containers/buckets in the the path.
### rclone lsl remote:path ###
List all the objects in the the path with modification time,
size and path.
### rclone md5sum remote:path ###
Produces an md5sum file for all the objects in the path. This
is in the same format as the standard md5sum tool produces.
### rclone sha1sum remote:path ###
Produces an sha1sum file for all the objects in the path. This
is in the same format as the standard sha1sum tool produces.
### rclone size remote:path ###
Prints the total size of objects in remote:path and the number of
objects.
### rclone mkdir remote:path ###
Make the path if it doesn't already exist
### rclone rmdir remote:path ###
Remove the path. Note that you can't remove a path with
objects in it, use purge for that.
### rclone purge remote:path ###
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 delete remote:path ###
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 check source:path dest:path ###
Checks the files in the source and destination match. It
compares sizes and MD5SUMs and prints a report of files which
don't match. It doesn't alter the source or destination.
### rclone dedupe remote:path ###
Interactively find duplicate files and offer to delete all but one or
rename them to be different. Only useful with Google Drive which can
have duplicate file names.
```
$ rclone dedupe drive:dupes

Server Side Copy
----------------
Drive, S3, Dropbox, Swift and Google Cloud Storage 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 (eg local) **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.
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 `k`
for kBytes, `M` for MBytes and `G` for GBytes may be used. These are
the binary units, eg 2\*\*10, 2\*\*20, 2\*\*30 respectively.
### --bwlimit=SIZE ###
Bandwidth limit in kBytes/s, or use suffix 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`
This only limits the bandwidth of the data transfer, it doesn't limit
the bandwith of the directory listings etc.
### --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](http://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 this is in
your home directory as a file called `.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.
### -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-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.
### --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.
### --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.
### -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 helps 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.
When using this flag, rclone won't update mtimes of remote files if
they are incorrect as it would normally.
### --stats=TIME ###
Rclone will print stats at regular intervals to show its progress.
This sets the interval.
The default is `1m`. Use 0 to disable.
### --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.
Specifying `--delete-during` (default value) will delete files while checking
and uploading files. This is usually the fastest option.
Specifying `--delete-after` will delay deletion of files until all new/updated
files have been successfully transfered.
### --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.
### -v, --verbose ###
If you set this flag, rclone will become very verbose telling you
about every file it considers and transfers.
Very useful for debugging.
### -V, --version ###
Prints the version number
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-bodies ###
Dump HTTP headers and bodies - may contain sensitive info. Can be
very verbose. Useful for debugging only.
### --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 - may contain sensitive info. Can be very verbose.
Useful for debugging only.
### --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.**
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](http://rclone.org/filtering/).
Exit Code
---------
If any errors occurred during the command, rclone will set a non zero
exit code. This allows scripts to detect when rclone operations have
failed.
# 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. The paths are matched without a leading `/`.
For example the files might be passed to the matching engine like this
* `file1.jpg`
* `file2.jpg`
* `directory/file3.jpg`
## 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. 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"
- doesn't match "afile.jpg"
- doesn't match "directory/file.jpg"
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"
### Differences between rsync and rclone patterns ###
Rclone implements bash style `{a,b,c}` glob matching which rsync doesn't.
Rclone ignores `/` at the end of a pattern.
Rclone always does a wildcard match so `\` must always escape a `\`.
## How the rules are used ##
Rclone maintains a list of include rules and exclude rules.
Each file is matched in order against the list until it finds a match.
The file is then included or excluded according to the rule type.
If the matcher falls off the bottom of 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`
## Adding filtering rules ##
Filtering rules are added with the following command line flags.
### `--exclude` - Exclude files matching pattern ###
Add a single exclude rule with `--exclude`.
Eg `--exclude *.bak` to exclude all bak files from the sync.
### `--exclude-from` - Read exclude patterns from file ###
Add exclude rules from a file.
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`.
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.
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.
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.
Prepare a file like this `filter-file.txt`
# a sample exclude rule file
- secret*.jpg
+ *.jpg
+ *.png
+ file2.avi
# 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`. 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.
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.
### `--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 |
| ---------------------- |:-------:|:-------:|:----------------:|:---------------:|
| Google Drive | MD5 | Yes | No | Yes |
| Amazon S3 | MD5 | Yes | No | No |
| Openstack Swift | MD5 | Yes | No | No |
| Dropbox | - | No | Yes | No |
| Google Cloud Storage | MD5 | Yes | No | No |
| Amazon Cloud Drive | MD5 | No | Yes | No |
| Microsoft One Drive | SHA1 | Yes | Yes | No |
| Hubic | MD5 | Yes | No | No |
| Backblaze B2 | SHA1 | Partial | No | No |
| Yandex Disk | MD5 | Yes | No | No |
| 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 checksum checks between filesystems they must support a
common hash type.
### 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.
Backblaze B2 preserves file modification times on files uploaded and
downloaded, but doesn't use them to decide which objects to sync.
### 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 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.
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:
```
n) New remote
d) Delete remote
q) Quit config
e/n/d/q> n
name> remote
What type of source is it?
Choose a number from below
1) swift
2) s3
3) local
4) drive
type> 4
Google Application Client Id - leave blank normally.
client_id>
Google Application Client Secret - leave blank normally.
client_secret>
Remote config
Use auto config?
* Say Y if not sure
* Say N if you are working on a remote or headless machine or Y didn't work
y) Yes
n) No
y/n> y
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
--------------------
[remote]
client_id =
client_secret =
token = {"AccessToken":"xxxx.x.xxxxx_xxxxxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","RefreshToken":"1/xxxxxxxxxxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxx","Expiry":"2014-03-16T13:57:58.955387075Z","Extra":null}
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```
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.
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
### 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 delete files permanently when requested. If
sending them to the trash is required instead then use the
`--drive-use-trash` flag.
### Specific options ###
Here are the command line options specific to this cloud storage
system.
#### --drive-chunk-size=SIZE ####
Upload chunk size. Must a power of 2 >= 256k. Default value is 256kB.
#### --drive-full-list ####
Use a full listing for directory list. More data but usually
quicker. On by default, disable with `--full-drive-list=false`.
#### --drive-upload-cutoff=SIZE ####
File size cutoff for switching to chunked upload. Default is 256kB.
#### --drive-use-trash ####
Send files to the trash instead of deleting permanently. Defaults to
off, namely deleting files permanently.
#### --drive-auth-owner-only ####
Only consider files owned by the authenticated user. Requires
that --drive-full-list=true (default).
#### --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`.
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 |
| html | text/html | An HTML Document |
| jpg | image/jpeg | A JPEG Image File |
| 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 |
| 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 |
### 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.
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
This will guide you through an interactive setup process.
```
No remotes found - make a new one
n) New remote
q) Quit config
n/q> n

* South America (Sao Paulo) Region
* Needs location constraint sa-east-1.
9) sa-east-1
* If using an S3 clone that only understands v2 signatures - eg Ceph - set this and make sure you set the endpoint.
10) other-v2-signature
* If using an S3 clone that understands v4 signatures set this and make sure you set the endpoint.
11) other-v4-signature

access_key_id = accesskey
secret_access_key = secretaccesskey
region = us-east-1

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
Current remotes:
Name Type
==== ====
remote s3
e) Edit existing remote
n) New remote
d) Delete remote
q) Quit config
e/n/d/q> q
```
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
### 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`.
### 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
```
e) Edit existing remote
n) New remote
d) Delete remote
q) Quit config
e/n/d/q> n
name> anons3
What type of source is it?
Choose a number from below
1) amazon cloud drive
2) drive
3) dropbox
4) google cloud storage
5) local
6) s3
7) swift
type> 6
AWS Access Key ID - leave blank for anonymous access.
access_key_id>
AWS Secret Access Key (password) - leave blank for anonymous access.
secret_access_key>
Region to connect to.
region> 1
endpoint>
location_constraint>
```
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.
Swift
----------------------------------------
Swift refers to [Openstack Object Storage](http://www.openstack.org/software/openstack-storage/).
Commercial implementations of that being:
* [Rackspace Cloud Files](http://www.rackspace.com/cloud/files/)
* [Memset Memstore](http://www.memset.com/cloud/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 swift configuration. First run
rclone config
This will guide you through an interactive setup process.
```
No remotes found - make a new one

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
### 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.
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
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:
```
n) New remote
d) Delete remote
q) Quit config
e/n/d/q> n

app_secret =
token = XXXXXXXXXXXXXXXXXXXXXXXXXXXXX_XXXX_XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```
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 MD5SUMs ###
Dropbox doesn't have the capability of storing modification times or
MD5SUMs so syncs will effectively have the `--size-only` flag set.
### 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.
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`.

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
### 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.
Amazon Cloud Drive
-----------------------------------------
Paths are specified as `remote:path`
Paths may be as deep as required, eg `remote:directory/subdirectory`.
The initial setup for Amazon cloud drive involves getting a token from
Amazon 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:

y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```
See the [remote setup docs](http://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 cloud drive
rclone lsd remote:
List all the files in your Amazon cloud drive
rclone ls remote:
To copy a local directory to an Amazon cloud drive directory called backup
rclone copy /home/source remote:backup
### Modified time and MD5SUMs ###
Amazon cloud 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 cloud drive website.
### 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 Cloud 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.
### Limitations ###
Note that Amazon cloud drive is case insensitive so you can't have a
file called "Hello.doc" and one called "hello.doc".
Amazon cloud 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 cloud 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.
Unfortunatly 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=50GB` option to limit
the maximum size of uploaded files.
Microsoft One Drive
-----------------------------------------
Paths are specified as `remote:path`
Paths may be as deep as required, eg `remote:directory/subdirectory`.
The initial setup for One Drive 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:
```
n) New remote
d) Delete remote
q) Quit config
e/n/d/q> n
name> remote
What type of source is it?
Choose a number from below
1) amazon cloud drive
2) drive
3) dropbox
4) google cloud storage
5) local
6) onedrive
7) s3
8) swift

Remote config
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
--------------------
[remote]
client_id =
client_secret =
token = {"access_token":"XXXXXX"}
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```
See the [remote setup docs](http://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 One Drive
rclone lsd remote:
List all the files in your One Drive
rclone ls remote:
To copy a local directory to an One Drive directory called backup
rclone copy /home/source remote:backup
### Modified time and hashes ###
One Drive 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 One Drive 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 One Drive is case insensitive so you can't have a
file called "Hello.doc" and one called "hello.doc".
Rclone only supports your default One Drive, and doesn't work with One
Drive for business. Both these issues may be fixed at some point
depending on user demand!
There are quite a few characters that can't be in One Drive 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.
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 remote
q) Quit config

client_secret =
token = {"access_token":"XXXXXX"}
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```
See the [remote setup docs](http://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
### 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 ###
Code to refresh the OpenStack token isn't done yet which may cause
problems with very long transfers.
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.
```
No remotes found - make a new one

endpoint =
--------------------
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 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
### 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 set on upload, read on download and shown in
listings. They are not used in syncing as unfortunately B2 doesn't
have an API method to set them independently 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. You can use the `--checksum` flag.
### 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 still be
available.
The old versions of files are visible in the B2 web interface, but not
via rclone yet.
Rclone doesn't provide any way of managing old versions (downloading
them or deleting them) at the moment. When you `purge` a bucket, all
the old versions will be deleted.
### Bugs ###
Note that when uploading a file, rclone has to make a temporary copy
of it in your temp filing system. This is due to a weakness in the B2
API which I'm hoping will be addressed soon.
### API ###
Here are [some notes I made on the backblaze
API](https://gist.github.com/ncw/166dabf352b399f1cc1c) while
integrating it with rclone which detail the changes I'd like to see.
With a couple of small tweaks Backblaze could enable rclone to not
make a temporary copy of all files and fully support modification
times.
Yandex Disk
----------------------------------------
[Yandex Disk](https://disk.yandex.com) is a cloud storage solution created by [Yandex](http://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:
```

--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```
See the [remote setup docs](http://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
### 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.
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 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.

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.

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](http://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](http://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.
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
```
