There are several imaging programs out there for backing up your computer and it is good to see that you are getting into the habit of imaging your drive... As you dont specify which copy you are using, other than an evaluation copy, I wouldn't worry about making an image backup until you get the RTM retail version all set up and ready to go. I personally use Acronis True Image Home 2010 for all of my backup needs.. It costs, but IMO is worth every penny... Let us know if you have any questions or problems..
