Well I suppose I cannot answer your Question with absolution; I do not use Windows for Back-up or Recovery however the very essence of recovering information is to completely wipe the slate clean and use what was working before.
You can however with other software Restore certain files; so for example if you do a complete scan on your system and it is clean, you then disk clean, defragment and what ever else then create a Back-up of your system; you find two weeks later that Tetris has a virus you can't get rid of but you've installed some new programs and customized your login profile so you don't want to do a clean Recovery; you can go into your back-up and restore just the Tetris data.
The Key to sucessful back-ups however....... is Back-up, Back-up, Back-up. Especially if your system changes; that is precicely to avoid this issue; chances are Tetris won't hold the virus for long!
Good luck hope that helps.
