My ex was late from work once a week because the company did commercial real estate logistics (sort of similar domain here) and she had the job of going to the secure data center and grabbing a backup disk out of the cage and transferring it to a safety deposit box.

The dumb thing was the bank was two blocks from the data center and less than eight (six?) from the office so catastrophic events might have hit both or all three. The owner kept a second copy at his house, and that was the only geographically separated copy.
