GSM vs QSave

GSM is free, open-source software for versioned game-save backups on Linux and Windows. It uploads backup sets to cloud storage, synchronizes the library between machines, and restores saves when needed. Ludusavi provides automatic game-save detection, while manual backup is available for games that are not detected. Rclone handles cloud uploads, and GSM creates SHA256 integrity files for each backup. Retention can be configured separately for each game. Restore choices include the newest backup, every stored backup, or the newest backup for one selected game. The project is designed for a shared Linux and Windows library without one system corrupting or deleting the other side's data. Linux distributions include graphical and text interfaces plus AppImage support. Windows offers a graphical build and a single-file EXE. GSM uses Rclone's copy command for cloud operations. The repository uses the MIT License, and its releases page lists “GSM - Definitive edition.”

QSave backs up video game save files to the user’s own Google Drive. It is free and open source, with downloads for Windows and macOS, including separate Apple Silicon and Intel Mac versions. Its game detection database supports more than 19,000 games, and the home page lists Steam, GOG, Epic and Battle.net. QSave searches installed games, and users can search and filter by those stores. Unsupported games can be added by selecting their save folder. Backups can be restored from Google Drive with one click. Cross-platform path remapping is intended to help carry saves between computers, and users can restore cloud-only games or choose a custom restore location. QSave keeps up to five backups per game, skips uploads when save files have not changed, and warns about possible restore or sync conflicts. Individual cloud backup versions can be deleted. The app can run in the system tray and optionally launch at startup. Windows and macOS may show an installation warning because QSave’s code-signing certificates cost money each year; Ko-fi contributions help fund those certificates.
