Clone allows you to backup your files. Clone can be run as either a screen saver or as a standard windows utility. Run as a screensave, clone backups up the data that is important to you while you take a break from your computer. This ensures you have a copy of your most important files backed up. Clone copies files from one location to another. This can be another hard disk, your CR-RW drive or any other media mapped to a drive or UNC path.
