I am still unsure, but more clear than I was, if that makes sense. If the network drive is the Z drive, then shouldn't the backup drive be a different drive?
Once all of the documents from My Documents are in one spot ... a shared file, I guess the easiest thing to do to make sure that he saves all My Documents files to the correct place is to actually change the name of My Documents to My Documents Shared? Obviously as with all the files, he's not going to want to lose a backup of important files, but at this point he's not sure which My Documents file he's actually saving to and he's confused -- hence only wanting to have one My Documents period.
I hope my rambling hasn't confused you.
Thanks again.
