S3 is like a giant RAID device to me, similar caveats apply from the "RAID is not a proper backup" arguments. There is not protection against deletions (malicious or accidental), writing over a file with a corrupted file, etc. Further, there is not protection against your account becoming errant in Amazon's eyes resulting in you getting locked out. And d2viant's point remains, Amazon could mess up or be subject to something out of their control. I'm not trying to diminish the excellent service and good track record they have, I use it myself as a piece of my total backup solution. But just a piece.
