    Minor disadvantage - only one backup.

    Power supplies and perhaps disk controllers can also cause common
    problems. We always back up to a different system just for this reason.
    In the case of tapes, the tape drive is located on a different computer
    to avoid the "common point of failure",

    If the hill is high enough and far enough away from the beach, the tidal
    waves won't get you, but watch out for those herds of rabid yaks, and
    the tourist drivers. It's always something.
