The Free and Open Source Software for Disk Imaging and Cloning

Clonezilla is a partition and disk imaging/cloning program similar to True Image® or Norton Ghost®. It helps you to do system deployment, bare metal backup and recovery.

Three types of Clonezilla are available, Clonezilla live, Clonezilla lite server, and Clonezilla SE (server edition).

Clonezilla live is suitable for single machine backup and restore.

While Clonezilla lite server or SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the hard disk.
This increases the clone efficiency. With some high-end hardware in a 42-node cluster, a multicast restoring at rate 8 GB/min was reported.
