Except that you would have to turn them both on for a restore. The cluster (with only one node running at a time) prevents having to boot a server just to run a restore. If you don't do many restores, then it wouldn't be an issue. I have to restore files that users have "lost" all of the time, so for me losing the ability to do a restore from a remote location would be a deal breaker. ------------------------------------------------------------------------------ Slashdot TV.
