Excellent Runs in Background, no hassles

I got mine from buy.com about three months ago, I set it to run every morning at 5am, so I don't have to mess with it. I check to see if it has been doing it's job and it does it. It is great to have it.
I will note that if you keep a lot of your documents on your desktop that you may have to add them manually. I did. Maybe there is some way to get it to that but I did not see it in the instructions so I just go in from time to time and add them. It is as easy as pie to add anything, just a click and drag, and you're done.
Also I purchased the 250 gig instead of the 500 because I would rather have more backup drives in case one goes down.
This drive is small and since it works with a simple usb, I can easily unplug and use it to back up my laptop.
I am happy so far. Also Seagate gives a five year warranty on this model -at least it did when I made my purchase.
