[https://digint.ch/btrbk/ Btrbk], a tool for creating snapshots and remote backups of btrfs subvolumes.

When transfering backups with btrbk of subvolumes used as a root filesystem, it is recommended to mount the Btrfs drive, in this example <code>/dev/sda1</code> with the root subvolume id 5 to a specific mountpoint. So in this case all subvolumes will be available as a subdirectory in <code>/btr_pool</code> an can be accessed by btbrk.

Following example configuration will create a weekly incremental backup of a local Btrfs subvolume called <code>nixos</code> and sends it compressed to a remote host <code>myhost</code> via ssh using provided authentication credentials. Note that this references the mount point <code>/btr_pool</code> from above.

Note that for transport stream compression using <code>lz4</code> to work, the package must also be installed on the target host.
