The purpose would be to have a backup if there is a catastrophic SAN failure. I know EMC and other storage vendors like to think that cannot happen but I've seen it four or five times over the years, mostly due to human error.

Your database is gone which makes the snapshot (if it still exists) invalid.

FYI, we will be using ExtremIO and there are a lot of good things about the VBlock. I'm just not comfortable with having zero backups.
