I think you're discounting the utility of simple checks.

Imagine you have weekly backups , but only for the past 26 weeks because of disk space. A file gets corrupted, but you only view it a year afterwards. You effectively have no way of recovering it.

Knowing something is wrong can be useful (though being able to fix it is even more useful).

That's exactly why I use par2 with all important data when backing it up. Bit corruption? So what?
