Often, these individuals with backup religion often tout their "superior" beliefs and practices much like an elitist or a jesus freak. Don't be around one of these people when your computer crashes and you don't have anything backed up; you will only get an "I told you so."
Bill: Steve lost all of his work files a few weeks ago, now he always creates a copy of his work onto his thumbstick, external hard drive, and even uploads things to an online service. This guy is crazy.
Jim: Man this guy has a bad case of backup religion.
Steve (whispering as he finishes up): all set and....amen.
