I think I may have done something silly. I am currently running a virtualized windows 7 environment within my Mac OS X. I wanted to backup both my files from Mac and Windows so I went out and purchased an external backup drive for my Mac thinking that using Time Machine, it will backup all files from Mac and Virtual Win7. I'm beginning to feel I made the wrong purchase. Is this a correct assessment? If so, how do other more intelligent human beings backup their mac files and win files using parallels? Thanks in advnace. ZackH.
