backup

(operating system)
("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 commonly refers to a copy of the files on a computer's disks, 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 backup software, differential backup, incremental backup, full backup. Compare archive, source code management.

backup

(1) A duplicate copy of data or of an entire storage drive on a separate storage medium. "Backup" is the noun; "back up" is the verb. See backup software, backup types, backup storage, copy data, backup and restore, disaster recovery and LAN-free backup.

(2) Additional hardware resources ready to take over if the main system fails. See fault tolerant.
