Backup btrfs subvolumes to an external USB device.

You can find the script and my anacrontab on github

Option -f
allows you to force a full backup.

The first time you run the script, it will create a full backup.
Subsequent runs create incremental backups using the --link-dest rsync options.

No automatic cleanup.

I use a 1TB ext2 filesystem as destination.
When file space get scarce, I switch to a second backup drive.
When that one fills up, I clean the first drive, and start using that one again.
