The problem with these programs is they never work 100% of the time.
I wouldn't waste your time with them at all. Instead get yourself and external back up hard drive (around $50-$100) and set up nortons ghost (shareware versions should be free) to do a back up of your entire comp every few days.
Then if you get a bug it takes no time at all to reboot your system with very little lost (you can even save anything from the last few days as a draft on g-mail or something and then reload them after the reboot- and loose nothing at all).
trust me, it's the only way to go!!!
