Backup
In the field of information technology, backup refers to the copying of data so that these additional copies may be restored after a data loss event. Backups differ from archives and backup systems differ from fault-tolerant systems. Backups are useful primarily for two purposes: to restore a computer to an operational state following a disaster (called disaster recovery) and to restore small numbers of files after they have been accidentally deleted or corrupted.
