1. anything kept in reserve to serve as a substitute in case
of failure or unavailability of the normal or primary

5. (Computers) A copy of a program or data from a computer
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.

6. (Computers) The act or process of creating a backup[5];
as, they performed a full system backup every weekend.

backup
(foldoc) | backup
("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.

pumpking
A humourous term for the token - the object
(notional or real) that gives its possessor (the "pumpking" or
the "pumpkineer") exclusive access to something, e.g. applying
patches to a master copy of source (for which the pumpkin
is called a "patch pumpkin").
Chip Salzenberg wrote:
David Croy once told me once that at a previous job, there was
one tape drive and multiple systems that used it for backups.
But instead of some high-tech exclusion software, they used a
low-tech method to prevent multiple simultaneous backups: a
stuffed pumpkin. No one was allowed to make backups unless
they had the "backup pumpkin".

backup rotation
(foldoc) | backup rotation
Any system for re-using backup media,
e.g. magnetic tape. One extreme would be to use the same
media for every backup (e.g. copy disk A to disk B), the other
extreme would be to use new media every time. The trade-off
is between the cost of buying and storing media and the
ability to restore any version of any file. One example is
the Grandfather, Father, Son (GFS) scheme.

backup software
(foldoc) | backup software
Software for doing a backup, often
included as part of the operating system.
Backup software should provide ways to specify what files get
backed up and to where. It may include its own scheduling
function to automate the procedure or, preferably, work with
generic scheduling facilities. It may include facilities for
managing the backup media (e.g. maintaining an index of tapes)
and for restoring files from backups.
Examples are Unix's dump command and Windows's
ntbackup.

differential backup
(foldoc) | differential backup
A kind of backup that copies all files
that have changed since the last full backup. Each
differential backup will include all files in previous
differential backups since the full backup so to restore a
version of a file, you only need to search the full backup and
the relevant differential backup.
Some systems support differential backup by associating an
"Archive" flag with each file and setting this flag whenever
the file is modified to indicate that it should be included in
the next backup. A differential backup does not change this
flag, whereas an incremental backup resets it.

incremental backup
(foldoc) | incremental backup
A kind of backup that copies all files
which have changed since the date of the previous backup. The
first backup of a file system should include all files - a
"full backup". Call this level 0. The next backup could
also be a full level 0 backup but it is usually much quicker
to do a level 1 backup which will include only those files
which have changed since the level 0 backup. Together the
level 0 and level 1 backups will include the latest version of
every file. Level 1 backups can be made until, say, the
backup tape is nearly full, after which we can switch to level
2. Each level includes those files which have changed since
the last backup at a lower level. The more levels you use,
the longer it will take to restore the latest version of a
file (or all files) if you don't know when it was last
modified.
Compare differential backup.
