	Have you really thought about this?  The correct way to
	backup the DNS is to use slaves.  If all is going well you
	will only loose a minute or two of changes.  You really
	don't want to roll back to what is in backup tapes.

	If you need to keep snapshots then use dig to extract a
	copy of the zone from the nameserver.
