If you scroll down the forum, to the thread I posted called xbox administrative mode info, I mention that I discovered that you can backup xbox one games over SFTP protocol. But backing up games pretty much does nothing without a way to load them. You can try burning the game to a blueray dl, to see if it works, honestly I heard tale that someone found a way to load a dump, way back when scene releases were being released. But those scene releases are long gone, and so is the the method, that some guy used to load a dump. I'm not even sure that story was real, it was a rumor around the internet.
