DeckSave

About DeckSave

DeckSave is a desktop application for backing up and synchronizing game save files across Steam Deck, Windows PCs, and Linux systems. It detects saves from both Steam and non-Steam launchers, helping users include games that are not managed through Steam’s own library. The application creates versioned backups, so earlier copies of a save can be retained as the files change. For moving saves between devices, DeckSave uses Syncthing. This lets a player keep game progress aligned across a handheld and computers, while versioned backups provide a way to preserve prior states. The combination addresses two related needs: protecting save data against unwanted changes and making it available on more than one supported device. The product is focused on game saves rather than general document synchronization. The supplied record does not list which individual games are detected, whether every launcher uses the same save location, or how conflict resolution works when saves change on multiple devices. It identifies the supported device families, detection of Steam and non-Steam saves, versioned backups, and synchronization through Syncthing. These are the established capabilities and dependencies users can rely on when considering the tool.
