We use something like these:
They have a certain amount of foam padding and are lockable.
Security-wise, our tapes go to an offsite vault. Think Iron Mountain but we're lucky enough to have a similar outfit locally that is more reasonably priced for us.
Short of that kind of setup..."always have a buddy"...don't transport the tapes alone from building to car, have a signed log documenting a chain of custody for who handles the tapes internally and out the door.
where do the tapes go offsite? If it's not to a locked vault, there's security on the far end too.
As already mentioned, consider encrypting the tapes regardless of your handling method.
I see in your profile that you work for an accounting firm so I would have to guess there's some level of auditing that goes on internally and externally. Your auditors and lawyers may have recommendations for data handling and protection.
If professional offsite vaulting with locked van pickup etc. isn't an option, additional steps you might take:
- Document a procedure for handling the tapes internally and log it daily including the chain of custody in your org. Get it signed off on so everybody is on the same page about the risks involved.
- If at all possible, don't take the tapes home. That's a lot of risk for your company and a lot of risk for you personally (you aren't bonded/insured for that and your home isn't a "secure" site). Short of a data vault, maybe a lock box at your company's bank. That might also help with security, access logging, and chain of custody.
- Depending on the amount of data, electronic vaulting may be an option where you back up securely over the wire. Yes, a tape holds a lot of data but if a relatively small amount of data is changing it might be an acceptable solution at an acceptable price.
Keep in mind that "ignorance is not bliss"...the risks exist regardless of whether you talk about them or not so it's better to talk about them. The best you can do is make sure everybody understands them, help figure out what the practical options are, and help carry out the agreed-upon solution.
