This protection utility allows you to clone the system that runs your computer in order to repair damage. Clones are compressed to save about 50 percent of your available disk space, and they can be saved on CDs. Clones are protected and invisible in the Finder to prevent you from inadvertently damaging them, and during cloning and restoration, Clone X displays the free space available on the destination disk in real time. You can also move a complete bootable disk to another. The copy will be bootable.
