Game Backup Monitor vs OpenSave

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.

OpenSave syncs game saves among a user's devices, including emulator saves and games outside Steam Cloud. It can identify games using an offline, community-maintained index of more than 20,000 titles, or track a folder or file selected by the user. Devices can find each other over the same Wi-Fi or pair over the internet with a room code, without an account or port forwarding. OpenSave keeps versioned snapshots and supports rollback and branches; when it finds conflicting saves, it asks the user how to resolve them. Optional snapshot backups can go to Google Drive, Dropbox, OneDrive, WebDAV, or a NAS folder. On a LAN, devices communicate directly. Internet syncing uses an encrypted connection to a stateless relay, but the encryption ends there and the relay could read forwarded data. Users can self-host the relay and manage its daemon and CLI through a local REST/WebSocket API. It is free and MIT-licensed, with Windows, Linux, Steam Deck, and macOS options. On a stock Steam Deck, the Linux tarball will not start; the site recommends the Flatpak.
