Rclone - rsync for cloud storage

Rclone is a really cool command line tool that can sync files and directories too and from many sources. A full list of sources can be found on their official website.

I personally use it for syncing local backups to Backblaze B2.

Installation #

There are a few ways to install but I prefer the script install:

To install rclone on Linux/macOS/BSD systems, run:

    $ curl https://rclone.org/install.sh | sudo bash

Configuration #

The easiest way to configure and get up and running is by:

    $ rclone config

And for my case I follow the Backblaze B2 steps:

(Steps extracted from Restic's site)

    No remotes found - make a new one
n) New remote
q) Quit config
n/q> n
name> remote
Type of storage to configure.
Choose a number from below, or type in your own value
[snip]
XX / Backblaze B2
\ "b2"

Storage> b2
Account ID or Application Key ID
account> 123456789abc
Application Key
key> 0123456789abcdef0123456789abcdef0123456789
Endpoint for the service - leave blank normally.
endpoint>
Remote config
--------------------
[remote]
account = 123456789abc
key = 0123456789abcdef0123456789abcdef0123456789
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:

Create 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

Disclosures #

Anything you sync without encryption has the potential of being publicly available and read in clear text. I recommend using encryption on any data that is synced to a publicly accessible storage.

Additionally, when using B2 storage please understand their access rules so that you can keep the repository private.
