Backup and FreeBSD/ZFS

[LoH]

If my memory serves, you're looking at something similar to taking a 
snapshot and then sending it to the tape device, so zfs send <snapshot> 
| (tape device access). This, IIRC, is functionally identical to 
dump/restore.

The Solaris ZFS Admin guide is generally helpful (even as we live in the 
FreeBSD world).
