From: "Stephen Costaras" <[EMAIL PROTECTED]> RAID of any level is NOT to be considered a 'backup' method. There are no assurances built into raid for data reliability. (ie. A program which writes corrupted data, a user who types Identical problem with TAPE!! In fact it's even worse... an rm -rf command in a wrong directory), et al. RAID only Hehe..you really think that it would be normally mounted? That an ordinary user would control the files?? protects you against a disk failure. Nothing more. Expand your thinking! Tape backup is needed in ADDITION to RAID for better solution. Sure, just give everybody free hardware. Don't run many budgets eh?
