Keith,

 I side 100% with your view on this. Was just checking to see if having RMAN comb the data for corruption was perhaps a part of the concern.

 I hope I don't run into folks at EMC who think a SAN array cannot fail. There is a reason IT employ disaster protection.

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.
