Other Services via rclone

The program rclone can be used to access many other different services and store data there. First, you need to install and configure rclone. The general backend specification format is rclone:<remote>:<path>, the <remote>:<path> component will be directly passed to rclone. When you configure a remote named foo, you can then call rustic as follows to initiate a new repository in the path bar in the repo:

rustic -r rclone:foo:bar init

rustic takes care of starting and stopping rclone.

As a more concrete example, suppose you have configured a remote named b2prod for Backblaze B2 with rclone, with a bucket called yggdrasil. You can then use rclone to list files in the bucket like this:

rclone ls b2prod:yggdrasil

In order to create a new repository in the root directory of the bucket, call rustic like this:

rustic -r rclone:b2prod:yggdrasil init

If you want to use the path foo/bar/baz in the bucket instead, pass this to rustic:

rustic -r rclone:b2prod:yggdrasil/foo/bar/baz init

Listing the files of an empty repository directly with rclone should return a listing similar to the following:

$ rclone ls b2prod:yggdrasil/foo/bar/baz
    155 bar/baz/config
    448 bar/baz/keys/4bf9c78049de689d73a56ed0546f83b8416795295cda12ec7fb9465af3900b44

Rclone can be configured with environment variables prefixed by RCLONE_, so for instance configuring a bandwidth limit for rclone can be achieved by setting the RCLONE_BWLIMIT environment variable:

export RCLONE_BWLIMIT=1M

As rustic allows to set environment variables in the config profile, you can alternatively use:

[global.env]
RCLONE_BWLIMIT = "1M"

For debugging rclone, you can set the environment variable RCLONE_VERBOSE=2.
