Clonezilla is an open source, free disk cloning, imaging, and backup solution. It is designed to be used for system deployments and data recovery, as well as for personal use. Clonezilla can be used to create and restore images of entire hard drives or partitions, as well as to clone disks or partitions to other locations. It can be used to clone a single hard drive or to clone multiple hard drives in parallel, with or without compression. Clonezilla can be run from either a bootable CD or USB drive, or from within a Linux or Windows operating system. It supports both local and remote backups, and can be used to create incremental or differential backups. It is highly configurable and can be used to create images of any size.
It is impossible to clone the disk in the trial version.
