GSM vs Ludusavi

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.”

Ludusavi is a free Rust tool for backing up PC video game save data. It covers more than 19,000 games and allows custom entries, with support for libraries such as Steam, GOG, Epic, Heroic, and Lutris. Users can operate it through a graphical interface or a command-line interface for scripting. Supported data includes file-based saves, Windows registry saves, Steam Proton saves, and Steam screenshots. Ludusavi is also available as a Playnite extension. For cloud copies, it integrates with Rclone remotes including Google Drive, OneDrive, Dropbox, Box, FTP, SMB, and WebDAV. Its synchronization process checks local and cloud saves before uploading changes and warns about conflicts. The tool supports scheduled backups and version history. Its backup information uses the Ludusavi Manifest, with information primarily sourced from PCGamingWiki. Portable releases are available for Windows, Linux, and Mac under the MIT License. One limitation is that it does not automatically support backing up on one operating system and restoring on another.
