My intention is to turn on System Protection on my NAS so that the Restore Previous Versions feature creates shadow copies of files on my network drive. I am currently running Windows 7 Home Premium and my local drives are my only options for System Protection. If I were to upgrade to Windows 7 Professional, would I be able to create shadow copies of files stored on my NAS? Thank you in advance.

I may be wrong about this, all I know is what the guy from EMC told me when he set up my device - if the device is seen by the computer as a local drive, using something like the iSCSI initiator the yes, you'll have all of the normal Windows options like Recycle Bin and Shadow Copies, but if it's just seen as a network device then no, you'll need a 3rd-party backup solution.

Well, I have a feeling you may be right about this. Thank you very much, you've just saved me $90.
