I have done this myself but haven't yet got around to releasing it. It's called mdbackup, is written in perl and basically goes off and connects to a bunch of remote servers (defined in a file called mdtab) via ssh or a smb mount, rsyncs the data to a location on your local zpool and then snapshots
