It does just what it says it will, give you a back up of your entire system. I am a shutterbug, so I store a lot of photos. It takes well over a hour for the  unit to go thu my complete system to find what is new,so it can back it up. I do have high speed dsl. It does not duplicate, just takes awhile to find what is new. <br /> <br />  Other than that, it is a quality unit, I Like it
