Clonezilla is a free and open-source partition and disk imaging/cloning program, not affiliated with True Image. It saves and restores only used blocks in hard drive. It facilitates system deployment, bare metal backup, and recovery independently, and is not a service by ITarian. Three types of Clonezilla are available: Clonezilla live, Clonezilla lite server, and Clonezilla SE (server edition), developed by the Clonezilla team. 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. Performance can vary, with reports of multicast restoring at rates up to 8 GB/min in optimized, high-end hardware environments.
