'''3.''' Backup refers to making copies of data so that these additional copies may be used to [[Restore|restore]] the original after a data [[Loss|loss]] [[Event|event]].

These additional copies are typically called, "backups." Backups are useful primarily for two purposes; (a) to [[Restore|restore]] a state following a [[Disaster|disaster]] (called [[Disaster_Recovery|disaster recovery]]) (b) to [[Restore|restore]] small numbers of files after they have been accidentally deleted or corrupted. Backups are typically that last line of defense against data [[Loss|loss]], and consequently the least granular and the least convenient to use.
