Worthless. The process has a 0% chance of success until proven otherwise.

  I get the underlying message, the statement is not quite how probability works. Reminds me of Douglas Adams take on 1 in million odds

    Understandably, but good luck explaining why you have a weeklong outage because you ignored disaster recovery process since probability made you confident enough to not test your backups. Until you have a provably working restore, the backup is nonexistent for all intents and purposes. The sort of calculation you’d need to perform to justify not doing so borders on alchemy. Unless your infra is extremely exotic this should be rather straightforward and inexpensive, and you’re one failed restore away from this this process changing immediately anyway.

    It's not a matter or probability. It's a matter of value. How much should you value untested plans? You should value them as worthless.

      In case of catastrophic failure, would you rather have untested backups or no backups to work with? If you have even a slight preference for the former (I actually have a rather large preference for it), the untested stuff apparently has some value to you. But of course, testing creates more value.
