I guess what I'm actually saying is that if you're concerned enough about reliability in the backups that you'd consider RAID-1, you might as well do it properly and rotate backup sets. (although I could see deploying RAID-1 at the clueless family member's house, if its not something that is going to get maintained)
If the backups maintain multiple point in time recovery sets (eg. Time Machine on the Mac), then protecting the backups with some redundancy is probably worth it to retain the backup timeline continuity.

Thats exactly the situation I am thinking of. More often than not, the person doing these things is clueless, although not entirely because that have realize they need a backup!
