disk cloning

What is disk cloning?

Disk cloning is the act of copying the contents of a computer's hard drive. The contents are typically saved as a disk image file and transferred to a storage medium, which could be another computer's hard drive or removable media such as a DVD or a USB drive.

Purposes of disk cloning include:

• System recovery, for example to return a hard drive to its original configuration after serious problems.
• Provisioning new computers before sale.
• As a "reboot and refresh" option for public computers.
• Recreating your system configuration on a new computer.
• To return a system to an original configuration with no personal data before selling or giving a computer away.

Disk cloning is also known as ghost imaging.
