De-dupe, will only transfer blocks changed since last snapshot. Performance, it's super damn fast. Because the ZFS snapshot itself is just a stream you can also compress it on the wire. Flexibility. You don't need to send the snapshot to another ZFS server. You could just take the ZFS snapshot streams and store them on say S3 compressed and re-assemble them. This would take custom tooling but it's definitely possible. You can restore super quickly to an older version if you haven't deleted the local snapshots. Similar to above but if you don't want to restore (as in make said snapshot the current active dataset) you can create a writable clone of one of the snapshots to play with it before committing to a restore or just to "go back in time" and play with something. As a bonus you also now have your data on ZFS which has tons of great benefits apart from the point in time snapshots.
