Why Backup and Recovery Is Important?
The main purpose as previously pointed out is to maintain a copy of your data. This is important to keep so in the event that you have a primary data failure you can get your systems back up and running.
While you can’t completely prevent data failure you can protect yourself by means of always have a backup and a means of recovering and restoring the backed up data. Data failure can be a result of software failure or hardware failure. Either of these can be brought on by human events, malicious attacks, natural disasters, accidental deletion, or corruption of data.
