You backups should be protection against at least: (a) user error, (b) normal hardware failure, and (c) disaster. user error: "I deleted something important, can you get it back" normal hardware failure: "Disk #7 needed to be replaced soon, er, now. SMART just failed it." disaster: "The building the server was in burned down / flooded" Snapshots really only cover (a). Normal RAID really only covers (b). Layering the two still doesn't address (c). -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
