Overview

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.

Who it is for

GSBS suits people syncing game saves across Windows, Linux, and macOS devices, including desktop, laptop, and Steam Deck setups. It may fit users who want version history, dashboard restores, and scheduled backups.

What is good

  • Detects running games and waits before syncing.
  • Translates Windows and Linux save paths.
  • Versioned saves can be restored from the dashboard.
  • Scheduled snapshots can be stored locally or on S3.
  • Free and distributed under the MIT License.

What to know first

  • Save contents are plaintext unless encryption is enabled.
  • Installers and binaries are not code-signed or notarized.
  • Server setup is recommended through Docker Compose.

Verdict

GSBS offers game-aware synchronization, save versioning, and scheduled backups across Windows, Linux, and macOS. Enable end-to-end encryption if save contents should not remain plaintext on the server and in backups.
