Backup is like an insurance, a failsafe, a fallback. Almost everything in an enterprise require a backup whether it is a Database, Application Server, Web server, etc. In case any catastrophic thing happens like power failures, machine faults, software bug, human error, etc., a backup comes as savior. It can be used to restore a failed/crashed system, Database, Application Server etc., It is the only thing available during disaster recovery to bring back the operations to normalcy. Any company using IT infrastructure must and should have a backup. The backup configuration must be tested for a failure and restore. Once the results are good, it can be implemented as standard.
Data backup involves copying and moving data from its primary location to a secondary location from which it can later be retrieved in case the primary data storage location experiences some kind of failure or disaster.
The purpose of the backup is to create a copy of data that can be recovered in the event of a primary data failure.
