I do the same, you should get Acronis True Image for backup, I use this tools for 3 years and recently join them as affiliate as well.

I have tried Newer version of Acronis True Image (I didn't upgrade, still using version 10), they have a very cool features called Try&Decide. When activated you can try anything on your computer including registry repair, you can try to corrupt your windows and Acronis True Image will record every action you take on your drive.
After testing, you can easily restore it to previous stat. But I still prefer to backup manually before using this Try&Decide feature (Only available in version 11).
Please don't take my word for it, try for yourself. I only share the best I used, there are still many best thing out there...
