|
|
======
|
|
|
|
[](http://rclone.org/)

|
|
|
Rclone is a command line program to sync files and directories to and from
|
|
|
|
* Google Drive
|
|
* Amazon S3
|
|
* Openstack Swift / Rackspace cloud files / Memset Memstore
|
|
* Dropbox
|
|

|
|
* The local filesystem
|
|
|
|
Features
|
|
|
|
* MD5SUMs checked at all times for file integrity
|
|
* Timestamps preserved on files
|
|
* Partial syncs supported on a whole file basis
|
|
* Copy mode to just copy new/changed files
|
|
* Sync mode to make a directory identical
|
|
* Check mode to check all MD5SUMs
|
|
* Can sync to and from network, eg two different Drive accounts
|
|
|
|
See the Home page for more documentation and configuration walkthroughs.

|
Install
|
|
-------
|
|
|
|
Rclone is a Go program and comes as a single binary file.
|
|
|
|
Download the binary for your OS from
|
|
|
|
* http://rclone.org/downloads/
|
|
|
|
Or alternatively if you have Go installed use
|
|
|
|
go install github.com/ncw/rclone
|
|
|
|
and this will build the binary in `$GOPATH/bin`.
|
|
|
|
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, Eg
|
|
|
|
rclone config
|
|
|
|
Usage
|
|
-----
|
|
|
|
Rclone syncs a directory tree from local to remote.
|
|
|
|
Its basic syntax is
|
|
|
|
Syntax: [options] subcommand <parameters> <parameters...>
|
|
|
|
See below for how to specify the source and destination paths.
|
|
|
|
Subcommands
|
|
-----------
|
|
|
|
rclone copy source:path dest:path
|
|
|
|
Copy the source to the destination. Doesn't transfer
|
|
unchanged files, testing first by modification time then by
|
|
MD5SUM. Doesn't delete files from the destination.
|
|
|
|
rclone sync source:path dest:path
|
|
|
|
Sync the source to the destination. Doesn't transfer
|
|
unchanged files, testing first by modification time then by
|
|
size. Deletes any files that exist in source that don't
|
|
exist in destination. Since this can cause data loss, test
|
|
first with the `--dry-run` flag.
|
|
|
|
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 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.
|
|
|
|
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 config
|
|
|
|
Enter an interactive configuration session.
|
|
|
|

|
|
|

|
|
|
|
General options:
|
|
|

|
|

|
|

|
|
--transfers=4: Number of file transfers to run in parallel.
|
|
-v, --verbose=false: Print lots more stuff
|
|
-V, --version=false: Print the version number
|
|
```
|
|

|
|
|
|
Local Filesystem
|
|
----------------
|
|
|
|
Paths are specified as normal filesystem paths, so
|
|
|
|
rclone sync /home/source /tmp/destination
|
|
|
|
Will sync `/home/source` to `/tmp/destination`
|
|
|
|
Swift / Rackspace cloudfiles / Memset Memstore
|
|
----------------------------------------------
|
|
|
|
Paths are specified as remote:container (or remote: for the `lsd`
|
|
command.) You may put subdirectories in too, eg
|
|
`remote:container/path/to/dir`.
|
|
|
|
So to copy a local directory to a swift container called backup:
|
|
|
|
rclone sync /home/source swift:backup
|
|
|
|
The modified time is stored as metadata on the object as
|
|
`X-Object-Meta-Mtime` as floating point since the epoch.
|
|
|
|
This is a defacto standard (used in the official python-swiftclient
|
|
amongst others) for storing the modification time (as read using
|
|
os.Stat) for an object.
|
|
|
|
Amazon S3
|
|
---------
|
|
|
|
Paths are specified as remote:bucket. You may put subdirectories in
|
|
too, eg `remote:bucket/path/to/dir`.
|
|
|
|
So to copy a local directory to a s3 container called backup
|
|
|
|
rclone sync /home/source s3:backup
|
|
|
|
The modified time is stored as metadata on the object as
|
|
`X-Amz-Meta-Mtime` as floating point since the epoch.
|
|
|
|
Google drive
|
|
------------
|
|
|
|
Paths are specified as remote:path Drive paths may be as deep as required.
|
|
|
|
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.
|
|
|
|
To copy a local directory to a drive directory called backup
|
|
|
|
rclone copy /home/source remote:backup
|
|
|
|
Google drive stores modification times accurate to 1 ms natively.
|
|
|
|
Dropbox
|
|
-------
|
|
|
|
Paths are specified as remote:path Dropbox paths may be as deep as required.
|
|
|
|
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.
|
|
|
|
To copy a local directory to a drive directory called backup
|
|
|
|
rclone copy /home/source dropbox:backup
|
|
|
|
Md5sums and timestamps in RFC3339 format accurate to 1ns are stored in
|
|
a Dropbox datastore called "rclone". Dropbox datastores are limited
|
|
to 100,000 rows so this is the maximum number of files rclone can
|
|
manage on Dropbox.
|
|
|
|
Google Cloud Storage
|
|
--------------------
|
|
|
|
Paths are specified as remote:path Google Cloud Storage paths may be
|
|
as deep as required.
|
|
|
|
The initial setup for Google Cloud Storage involves getting a token
|
|
from Google which you need to do in your browser. `rclone config`
|
|
walks you through it.
|
|
|
|
To copy a local directory to a google cloud storage directory called backup
|
|
|
|
rclone copy /home/source remote:backup
|
|
|
|
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.
|
|
|
|
Single file copies
|
|
------------------
|
|
|
|
Rclone can copy single files
|
|
|
|
rclone src:path/to/file dst:path/dir
|
|
|
|
Or
|
|
|
|
rclone src:path/to/file dst:path/to/file
|
|
|
|
Note that you can't rename the file if you are copying from one file to another.
