Clonezilla

Clonezilla is a great open source cloning system that allows cloning to multiple computers. In the proprietary world, this is done with Symantec’s Norton Ghost Corporate Edition, which does it with multicasting. Fortunately, Clonezilla also has support for multicasting and unicasting! All you have to do is set up a Clonezilla server and watch the magic happen.
Booyah. Watch the cloning magic happen.
