"Backups aren't backups until they've been tested."
They really are Schrödinger's backups until a test restore takes place. This is one area where people cut corners a lot because no one cares about backups until they need them. But it's worth the effort to do them right, including occasional, scheduled manual testing. If you can't restore the data/system you're going to be the one working insane hours to get things working when a failure occurs.
And then there's the aftermath. Unless you are lucky enough to work for a blame free organization major data loss in a critical app due to a failure of the backup system (or lack thereof) could be a resume generating event. If you're ordered to prioritize other things over backups make sure you get that in writing. Backups are something everyone agrees is "critical" but no one wants to invest time in.
