I've have been backing up my Poser files since the late 90's....no way in hell did I ever wan't to loose stuff in my runtime that I paid for or work files.

I'f your runtime+files is small enough to fit on a DVD or two do that...If more, buy an external HD and back up every so often. I back up every couple of months which is probably not smart but at leist it's there. Never had a problem with my PC or Mac when I used them.
