2 definitions found From WordNet r 1.6 [wn]: backup n 1: someone who takes the place of another (as when things get dangerous or difficult); "the star had a stand-in for dangerous scenes"; "we need extra employees for summer fill-ins" [syn: {stand-in}, {substitute}, {relief}, {backup man}, {fill-in}] 2: (computer science) a copy of a file or directory on a separate storage device; "he made a backup in case the original was accidentally damaged or erased" [syn: {computer backup}] From The Free On-line Dictionary of Computing (13 Mar 01) [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 {incremental backup}. Compare {archive}. (1998-04-17)
