Clonezilla

Clonezilla is a free program for backing up complete Operating Systems and optionally restoring them to HDD of equal or larger size

• recent releases can also restore to a smaller HDD, provided that the used space is smaller than the HDD.

It is not well suited to routine data backup, although users data within the partition(s) will be backed up.

Be certain to read the documentation thoroughly before using Clonezilla, particularly if cloning MS Windows system, where the process has many "gotchas"

Clonezilla may be downloaded from

http://clonezilla.org

Alternatively, a more general purpose utility CD ISO image containing it may be purchased from
