Alternatively, if you have the luxury - `zfs snapshot`.

  Having a snapshotting storage system (NetApp) once saved a lot of pain when I accidentally deleted the wrong virtual machine disk from an internal server (hit the system disk instead of a removed data disk) I was able to recover the root disk from a snapshot and bring up the machine in less than an hour. Snapshots are not a backup strategy, but they make me sleep better at night regardless.
