A backup vendor once pointed out that backup was the most misnamed product/function in all of computerdom. He argued it should really be referred to as restore, since when the chips are down that's what you really, really care about. That really resonated with the young sysadmin I was at the time.

Very similar to the story about the planes with holes coming back in WWII and the initial analysis of adding more armor to where the holes were, when someone flipped it and pointed out that armor was needed where the holes weren't since planes with holes in those spots weren't the ones coming back.
