Also, easier restore and snapshot deletion. Consider how you would restore using incremental ZFS snapshots. You'd have to pull all the snaphots, unpack the base snapshot and then sequentially unpack each incremental snapshot. In tarsnap, the server will compute the 'snapshot' you want for you, and will only send you the data blocks that belong to that snapshot. In tarsnap, you can also delete any snapshot you want, and only blocks belonging exclusively to that snapshot will be deleted. In your system, deleting a snapshot means you lose all snapshots from that one until the next full snapshot. Also, in ZFS you're limited to backing up complete datasets, but with tarsnap you can backup any set of files you want.
