Not as an operating system, but rather a small
bootable Linux distribution for the x86 platform that can be used to
clone partitions and entire hard drives. Clonezilla Live makes it
possible to create 1: 1 backup copies of an entire system - at almost
incredible speed. The distribution is based on a minimized live image of
Debian equipped with Clonezilla tools. A CD, DVD, or USB device can be
used as a medium, which also serves as a storage device for the copied
data. Alternatively, a network resource, such as an SSHFS.
