Cloning is nothing but the copying of the contents of a server hard disk to a storage medium (another disk) or to an image file. Disk cloning is quite useful in modern data centers for:

  1. Full system backup.
  2. System recovery.
  3. Reboot and restore.
  4. Hard drive upgrade.
  5. Converting a physical server to virtual machine and more.

In this post, I’m going to list the Free and Open Source Software for Disk Imaging and Cloning that you can use for GNU/Linux, *BSD and Mac OS X desktop operating systems.
