Btrbk is a Perl-based command-line backup tool for btrfs subvolumes that creates atomic snapshots and transfers them incrementally to local or remote backup locations via ssh. It is configured through a config file supporting flexible retention policies, multiple destinations, and encrypted backups to non-btrfs storage.

Use cases

• create atomic snapshots of btrfs subvolumes on a schedule
• incrementally back up btrfs subvolumes to a remote server over ssh
• manage snapshot retention policies for laptop backup disks
• back up docker and lxc container subvolumes with wildcards
• send encrypted backups to non-btrfs storage
• recover from interrupted backups on removable drives
• archive snapshots to offline storage

When to choose

• your filesystem is btrfs and you want snapshot-aware incremental backups
• you need cron-driven periodic snapshots with flexible retention
• you back up multiple hosts to a central server over ssh
• you want a single-script tool with no special dependencies

When to avoid

• your filesystem is not btrfs
• you need block-level or full-disk imaging rather than subvolume snapshots
• you need a GUI-driven backup solution
