The beauty of using a handheld gaming device like the Steam Deck is the ability to take and play games anywhere. The convenience of playing anywhere around the home or taking it on a long journey can't be understated. However, some games can be more demanding on the battery life and potentially switch the machine off. Thankfully, there's a free plugin called Steamback created by Geeksville. The Steamback plugin creates snapshots of the game for you to restore. It's also a great way to revert to a game's save if you regret any decisions using a title's default one-save file system, like losing all your Runes in Elden Ring.
