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
- Google drive
- Amazon S3
- Swift / Rackspace Cloudfiles / Memset Memstore
- Dropbox
- Google Cloud Storage
- Local filesystem
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.
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. 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 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.
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.
rclone help
Prints help on rclone commands and options.
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 MD5SUM and size to determine if files are equal.
This is very useful when transferring between remotes which store the MD5SUM on the object which include swift, s3, drive, and google cloud storage.
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 in combination
with the -v flag to see what rclone would do without actually doing
it. Useful when setting up the sync command.
--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.
--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.
--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.
--cpuprofile=FILE
Write cpu 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.
