Backups should be performed on a regular basis. The frequency of your back ups will depend upon the maximum acceptable amount of work that would be lost in the event of a catastrophic failure.
While data backups would seem to offer an effective shield against threats, backups do not always provide comprehensive data protection. That is because the data backup plans developed by many companies are not fully realized or, worse yet, not followed. What is more, individuals often fail to test the restore capabilities of their backup media. If the backups are faulty, a simple data loss can quickly become a data disaster. Finally, even if backups are successful, they only contain data collected during the most recent backup session. As a result, a data loss can potentially rob you of your most current data, despite your backup attempts.
