ZFS snapshots support for rsync handler
I want to use ZFS snapshots on the backup destination.
This is my first attempt, i'll be glad to fix it to be includable in backupninja, right now it only Works For Me(tm) :)
Features: it only checks if zfs-auto-snapshot is installed and if the destination mountpoint is a ZFS dataset. If it is, it runs zfs-auto-snapshot on the mountpoint, keeping 7 daily snapshots.
I'm open to ideas how to implement this further.
