One of the basic premises behind a solid backup strategy is that if disaster hits that it does not hit simultaneously in all places. If that does happen then I think you have different problems to contend with than trying to restore your backups.

I keep a backup of my home data at the office (encrypted volume). Plus another one at a family member's house halfway across the continent (disks are exchanged at family get-togethers)

It's not hard - you just need to do it.
