Checkpoint64 vs GSBS

Checkpoint64 backs up PC game save folders to the cloud and lets users browse and restore earlier versions. It checks folders every 60 seconds and uploads changed files after a game finishes writing, with each upload recorded as a version. It supports games from Steam, GOG, and Epic, along with emulators and modded setups; presets cover more than 140 games and seven emulators. For shared saves, a lock limits uploads to its holder. Locks expire, and a teammate taking over gets a warning and a logbook entry. Linking Discord can notify teammates when someone manually commits or restores a shared save. The app is listed for Windows 10 and 11, macOS on Apple Silicon, and Linux; Steam lists Steam Deck support. The free plan includes 20 MiB of cloud storage per space and does not expire. Pro costs €5 a month, while Lifetime costs €10, paid once. Save files are encrypted in transit and at rest, but the service is not end-to-end encrypted or zero-knowledge.

GSBS is a free game-save synchronization and backup service for Windows, Linux, and macOS. Clients connect through a central server, detect when a supported game is running, and wait to sync until it closes. The client checks game installations across Steam, Epic, GOG, Ubisoft, EA, Xbox, Heroic, Lutris, Bottles, and Prism against a PCGamingWiki manifest. It translates save paths between Windows and Linux, including Proton paths. Save files are versioned and can be restored through the web dashboard. Optional end-to-end encryption uses client-side AES-256-GCM with Argon2id; without that option, saves are plaintext on the server and in backups. Scheduled tar.zst snapshots can include the database, keys, and saves, with storage on local disk or S3. GSBS can send webhook, Discord, and ntfy alerts, including for conflicts, quota, and backups. The project recommends Docker Compose for the server and provides a Windows server setup executable. It is distributed under the MIT License.
