btrbk is a backup tool for btrfs filesystems that creates and manages snapshots and remote backups. It uses btrfs send/receive for efficient incremental backups and supports complex retention policies.
Configuration is defined in /etc/btrbk/btrbk.conf, specifying source subvolumes, snapshot locations, and backup targets including remote hosts via SSH.

-v, --verbose

Increase verbosity

Show progress during transfers

Same as dryrun command

Use alternate configuration file

/etc/btrbk/btrbk.conf

Main configuration file defining source subvolumes, snapshot locations, backup targets, and retention policies.

run

Create snapshots and run backup routines

Only create snapshots (no backups)

Resume incomplete backups

Show what would be done without making changes

Display statistics

List configured items

Delete outdated snapshots

Only works with btrfs filesystems. Remote backups require SSH access and btrfs on the remote host. Retention policies should be tested with dryrun first.
