I'm sorry but you are wrong. Time Machine is the same as Rollback RX. Paragon is a system image stored on an external HDD. A system image is a complete mirror image of your pc stored externally. Time Machine is a glorified system restore. It cannot save you if and when you have a HDD failure.
Think of a system image as a quick reformat without reinstalling everything. If you already have an external HDD then use Paragon. Also Windows 7 comes with its own backup system image utility.
