I worked at a wedding photography/videography place a few years ago and we did a lower tech version of this. The owner had a storage array at the office and at home, and he'd cart an external back and forth daily. This way there were two copies of all work, and three of the most recent: one at the office, one at his home, and the most recent work (that which hasn't been delivered) on the portable drive.
