        onto a data-storage medium, usually one that may be
        removed to safe storage at a distance from the computer;
        it is used to preserve data for use in the contingency
        that the original data on the computer may be lost or
        become unusable. A backup that is removed from the
        building housing the computer system (to provide
        protection against loss of data in a disastrous event such
        as a fire) is called off-site backup. Also used
        attributively; as, backup copy.

From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  backup
       
           (Sometimes "back up" when used as a verb) A
          spare copy of a file, file system or other resource for use in
          the event of failure or loss of the original.
       
          The term is most commonly used to refer to a copy of all the
          files on a computer's {disks} which is made periodically and
          kept on {magnetic tape} or other removable medium (also called
          a "{dump}").
       
          This essential precaution is neglected by most new computer
          users until the first time they experience a {disk crash} or
          accidentally delete the only copy of the file they have been
          working on for the last six months.
       
          Ideally the backup copies should be kept at a different site
          or in a fire safe since, though your hardware may be insured
          against fire, the data on it is almost certainly neither
          insured nor easily replaced.
       
          See also {differential backup}, {incremental backup}, {full
          backup}.  Compare {archive}.
