It would be easy to setup a backup system where all backups are encrypted with a set of randomly generated keys. (1 key for each user/service pair or something). The keys are going to be (relatively) tiny, so they could be kept on non-archival storage. If a user's data needs to be deleted for whatever reason, simply discard the user's corresponding encryption keys. That way you can effectively wipe the user's archive without needing to touch the tapes themselves. |
