Ok so lots of valuable company data is moved from your facility to a bank by an employee on a weekly basis? I think the weakest link in the chain is you. I'm just saying what's to stop someone from taking the tapes from you in transit? Sure the bank has good security (cameras, security guards, a vault), and your company most likely has good security too but when your in transit couldn't someone stop you and take the tapes from you (by force if needed)? Just out of curiosity are there any backup software packages (like something made by Veritas or Computer Associates) that will not only compress data before backup but also encrypt it?
