The closest thing there is is called an imaging program, such as Norton Ghost. These take something of a snapshot of your system, and allow you to restore it to that point.
However, relying on these images as a backup is a bad idea. You want to be sure to back up your documents, photos, etc, separately just in case.

if anything were to happen to my PC ,could i just copy back all the data on the CD including the OS,or do i have to reinstall my OS then copy back the rest of the files?
