Is zfs send and zfs recv not an option?
(Sending a ZFS Snapshot)

 From Nexenta course I once followed; Snapshot early, snapshot often. 
It's better to do snapshots every 5 minutes and send that differential 
snapshot to a second machine with zfs send/recv, than to use other means 
of backing up live systems.
