the ZFS team is working on a zfs send -r (recursive) option to be able to recursively send and receive hierarchies of ZFS filesystems in one go, including pools. So you'll need to do it one filesystem at a time. This is not always trivial: If you send a full snapshot, then an incremental one and the target filesystem is mounted, you'll likely get an error that the target filesystem was modified. Make sure the target filesystems are unmounted and ideally marked as unmountable while performing the send/receives. Also, you may want to use the -F option to receive which forces a rollback of the target filesystem to the most recent snapshot. I've written a script to do all of this, but it's only "works on my system" certified. I'd like to get some feedback and validation before I post it on my blog, so anyone, let me know if you want to try it out.
