Clonezilla is free and open source software for disk imaging and cloning, under the GNU General Public License (GPL) Version 2. 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, and Clonezilla lite server or SE is for massive deployment, and can clone 40 plus computers simultaneously.
CloneZilla has several scenarios where it can be used in business. Firstly the main purpose for us is for imaging of larger number of systems with varying specifications and operating systems in quick succession. However we have also used it for "point of time" imaging of systems for when employees have left the company or have a full metal backup made.
Whilst other imaging and deployment suites provide nicer interfaces which suit less technical staff, they do have quite significant price differences in comparison to CloneZilla. CloneZilla not only provides us a significant number of features, it provides a full imaging solution at a price which no one can compete with!
