I am looking for a thread that discusses how to back up and restore game updates. I think this is a good idea, first from a historian's perspective, to preserve different states of a game's development post-release, as well as to speed up re-adding updates to archived titles and to save space on SD media for games that are not currently being played. I have not begun the investigation into how this may or may not work, but it's always good to have input from those who may already be in-the-know, so please comment or reply with anything you can add to this thread. Thanks!!
