I've tried this in the past and it did not work. The Desktop Manager seems to only back up personal settings and data files. Applications are completely ignored and I found that I had to use some other means to back up the applications themselves, however the settings for each application is not restored. I still have to go through each application's setup wizard. But since I haven't done this in a while, I can't be sure.
