This is why the saying goes: "RAID is not a backup system". RAID stands for "Redundant Array of Independent Disks". So if you experience corruption on one disk, then RAID diligently copies that corruption to the other disks in the array, so you end up with "redundant corruption". RAID is (should be!) used to gain better system uptime or speed. It doesn't do diddly squat for backups. RAID systems need to be backed up just the same as non-RAID systems do. I guess IA didn't know that.
