Easy: Restoring from a RAID 1 device

Thanks for that super helpful link! I'm going to read through before I try the solution recommended in the earlier comment, if only to familiarize myself with the way the system works.

In our case the entire backup process is stored to the same disk, including all inventory and catalog files, and that entire disk is mirrored on to a second disk that is pulled out on Monday morning (when no backups are running) and replaced with the next disk in queue.
