Clonezilla

Clonezilla is an open source imaging program. Like Norton Ghost, Clonezilla can create an image of a computer, which can be used for backup or to apply the image to another machine. Clonezilla can be used on an imaging server, as a bootable CD or a bootable USB stick.

Note that there are special requirements for cloning onto systems with a RAID array. For example there are special instructions to install Inveneo Hub Linux from Clonezilla.
