Yes. Predictably enough the command is 'zfs send ...' -- with a
counterpart 'zfs receive ...' See zfs(1) for details. You have to send
a snapshot, or the delta between a previous snapshot and a more recent
one. However, it's not to difficult to turn that into effectively
sending the state of a live filesystem so long as there aren't too many
changes going on.
