Summary

GSBS is a game-save synchronization and backup service for Windows, Linux, and macOS, built around a central server and client apps. Its clients look for games across stores and launchers including Steam, Epic, GOG, Ubisoft, EA, Xbox, Heroic, Lutris, Bottles, and Prism, then wait until a detected game closes before syncing. GSBS can translate save locations between Windows and Linux, including Proton paths. It keeps versions of save files, which users can restore from a web dashboard. Optional end-to-end encryption protects saves with client-side AES-256-GCM and Argon2id; without it, save contents remain readable on the server and in backups. Scheduled tar.zst snapshots can include the database, keys, and saves, stored locally or on S3. Alerts can be sent through webhooks, Discord, or ntfy. The service is free under the MIT License, supports multiple users and devices, and recommends Docker Compose for server deployment; a Windows server setup executable is also available.

Who it is for

GSBS suits people managing game saves across multiple Windows, Linux, or macOS devices, including desktop, laptop, and Steam Deck setups. It may also fit users who want to self-host and manage their own backups.

What is good

  • Waits for games to close before syncing saves.
  • Translates save paths across Windows and Linux.
  • Versioned saves can be restored from the web dashboard.
  • Scheduled snapshots can be stored locally or on S3.
  • Optional client-side end-to-end encryption is available.

What to know first

  • Saves are plaintext unless end-to-end encryption is enabled.
  • Installers and binaries are not code-signed or notarized.
  • Server deployment recommendation is Docker Compose.

Verdict

GSBS combines cross-platform save syncing with version history, restore, and scheduled backups. Users should account for its plaintext-by-default storage and unsigned installers when choosing how to deploy it.
