Disk wear out is inevitable and a common problem we face in everyday life. Creating an image of your hard disk is the best way to protect all your system data from any disk failure or accidental deletion of critical system files or software corruption.
Restoring data from a drive / system image is less time consuming as you do not need to install the operating system separately then restore the backed up data, to get your system up and running. As disk cloning duplicates your entire hard drive, you can restore your system to its initial state in much less time.
