I believe that is a very big danger with a raid. I never recommend a single raid array for all your backups. Two raid arrays on separate raid controllers (preferably separate machines) each containing at least 1 backup of everything are fine but a single raid to hold your only backup copy is dangerous. > Where as > if one disk dies, we only lose what was on that disk.
