I've learned about a hosting provider who's definition of "onsite backup" includes "snapshots of the SAN storage stored on the same SAN and the same RAID 50 array".
Does this sound right to anyone? I mean - I expect everyone to say "it depends on what you are trying to protect from" but assuming it's meant to protect from a disaster above "accidental deletion". There is no other form of backups offered (e.g. they don't offer to copy the snapshot to another SAN array or to tapes, for instance).
Has anyone else found such a definition actually used in production environments?
