Trying to figure out how to backup #ZFS... I need backup system to keep a copy of ZFS datasets from remote system on its zpool. So first I snapshotted remote dataset and send/recv it over ssh, now I have a copy dataset. But now I need to automatically pull updates... for that I need incremental (-i) send, but for that I need to make another snapshot and explicitly specify the two snapshots... this get complicated.

And then should I make snapshots on the backup system or leave the snapshots on the remote system...
