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 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 backup software, differential backup,
incremental backup, full backup. Compare archive,
source code management.
