I like the idea of having something more reliable than Windows's system restore. If your windows o/s crashes, you may find you are unable to use system restore to get out of trouble. The fact that you can access Rollback Rx before Windows is supposed to start appeals to me. However, I don't like the hard drive errors and the slow start up caused by Rollback Rx. I currently use both AEOMI Backupper and Windows own backup system. Both have gotten me out of trouble.
