You have to 'zfs recv' your datastream and expand it out as a
filesystem.  Then you can simply copy individual files back to your live
system, or you can do a zfs send / zfs recv of a single dataset to
restore that.

You can easily 'zfs recv' the datastream into a different root directory
than it came from -- so you won't end up overwriting onesystem with the
backup of another.

There are scripts to do this in ports, but here's some I wrote myself:

I never did get round to writing a 'zfs-restore' script though.
