I have an 810 and I would like to back up my phone to my PC rather then to the Cloud (paranoid because of PRISM)... However when I plug in my phone to my PC and click on "My Computer" then choose the Windows Phone I get an empty folder. No hidden files, no mention of size of the storage space or amount used, nothing at all. I have also downloaded and installed the wp app to my computer (Win 7) and still nothing. Is there something in the phone that I have to turn on or unlock for me to have access to my data?
