The entire premise of claiming to have backups is that you are the fork who ensures multiple copies have no commonalities, no overlap, in what keeps them healthy. You can delegate if you aren't interested in DIY and getting in the trenches, but you still need to apply the original premise by being a fork and delegating to multiple separate entities... Otherwise, you can't claim to have backups, despite the fact that the one basket you put your eggs in can legitimately claim to have backups.
