I used a 320 GB Click Free before and always just plugged it in and it backed up changed or new files. I thought the C6 was supposed to do the same thing, but for everything on the computer, but it generates a completely new all-computer backup each time I plug it in. I don't want to keep it plugged in because I'm concerned about lightning strikes. And it takes 12 or more hours to do that complete backup! I'm running Windows 7 on a desktop with 3 GB memory and a 500 GB hard drive that is not overly full. The computer generally works fine. Please help!
