Game Backup Monitor vs GSM

Game Backup Monitor detects games while they are running and backs up saved games after play ends, compressing them with 7-Zip. It can monitor other PC applications too, and supports an unlimited number of monitored games with individual settings. Optional features track total play hours and separate sessions, and users can launch monitored games from the program. It detects games running through DOSBox, ScummVM, or Wine, and can import unofficial configurations from the Ludusavi Manifest. Cloud backup requires pairing the software with a cloud storage provider and folder synchronization client. The program is free for Linux and Windows. Windows requires .NET Framework 4.8; Linux requires Mono and additional packages, including SQLite3 and 7-Zip. The maker describes the project as complete, with maintenance updates but no major changes. Its application is not digitally signed, so Microsoft may flag the installer or executable as unsafe. Development testing verifies Windows 11 and Linux Mint 21.

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.”
