Clonezilla

Clonezilla is a free software disaster recovery, disk cloning and deployment solution.

Clonezilla Live

'Clonezilla Live' enables a user to clone a single computer's storage media, or a single partition on the media, to a separate medium device. The cloned data can be saved as an image-file or as a duplicated copy of the data. The data can be saved to locally attached storage device, a SSH server, Samba Server or a NFS file-share. The clone file can then be used to restore the original when needed.

The Clonezilla application can be run from a USB-flash-drive, a CD-ROM, or a DVD-ROM. Clonezilla requires no modification to the computer; the software runs in its own booted environment.

Clonezilla Server

Clonezilla Server is used to clone many computers simultaneously across a network. This is done using a DRBL server and computer workstations that can boot from a network.
