Why maintaining a procedure guide for backup is important?

The main reason for data backup is to save important files if a system crash or hard drive failure occurs. There should be additional data backups if the original backups result in data corruption or hard drive failure. Backups are necessary if natural or man-made disasters occur. The purpose of the backup is to create a copy of data that can be recovered in the event of a primary data failure. Backup copies allow data to be restored from an earlier point in time.
