GSM

What GSM is

GSM is a free, open-source tool for keeping versioned game-save backups across Linux and Windows. It can upload backups to cloud storage, synchronize a backup library between machines, and restore saves when needed. Ludusavi provides automatic game-save detection, while manual backups cover games that are not detected. Rclone handles cloud uploads, and GSM creates SHA256 integrity files for backups. Retention can be set separately for each game. Restore options include the newest backup, every backup, or the newest backup for a chosen game. The project is designed for Linux and Windows systems to share a library without one side corrupting or deleting the other's backups. Linux users have a graphical interface, a text interface, and AppImage support; Windows distribution includes a graphical interface and a single-file EXE build. GSM uses Rclone's copy command for cloud operations. Its repository is published under the MIT License, and the releases page lists “GSM - Definitive edition.”

Who it suits

GSM suits players who want versioned game-save backups and cloud synchronization across Linux and Windows machines. It also supports manual backups for games automatic detection misses.

Getting started

1. Open the GSM GitHub repository.
2. Choose the Linux or Windows distribution for your system.
3. On Linux, choose the GUI or TUI and use AppImage support if suitable.
4. Use automatic detection through Ludusavi or add a manual backup for a game it misses.
5. Configure Rclone for cloud uploads and set retention per game.

Verdict

GSM combines game-save detection, versioned backups, cloud uploads, and restore options in one cross-platform tool. Its manual backup option helps cover games it does not detect automatically.
