I really need this mode of operation for > undeleting users' files etc. 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: https://github.com/infracaninophile/zfs-backup I never did get round to writing a 'zfs-restore' script though.
