I had the chance to try out the built in backup from windows 7. Not bad, I may have to start using that instead of the scripts and tools I currently use. I was impressed with what I saw, so I setup the backup and will try it for a few weeks.
Here is a great article showing all the steps. I found it was pretty straight forward to use with my network share.
