Nice article. What good does a backup do if it can't be restored? None. A disaster is not the time to find your backup plan is useless.

I would also add figuring out the timings so you know how long it will take to get the tapes and do the restore. Let everyone know it so there are no expectations that can't be met. And, test it at the most inconvenient time to see how long it takes to get it from the offsite vendor.
