Now that you say that (about points 1 & 3) it is actually obvious; sorry about that.

We do have overnight backups going to tapes in an external data vault.

Thanks very much for the script; I'll do that now. I really appreciate the help. This new job is not what was advertised, but I'm trying to make the best of it as it's a good learning opportunity (assuming I don't break everything) ;-).
