Btrfs Bootable Backup Bimage is a script that creates incremental backups of a running Linux system in the form of bootable disk image. It does so with the magic of dd and btrfs snapshots. It is intended to have a reasonably low downtime on systems where you cannot or don't want to have a RAID setup, like single board computers used as servers.

WARNING!! This is in a very early development stage and will most likely destroy all your data!
