FastBack vs FolderRewind

FastBack is a free, open-source Minecraft mod for incremental world backups: snapshots save changed parts rather than the entire world. Backups can be stored locally, on a Git server, or on a network volume without a Git server. They can run when a world shuts down or after Minecraft autosaves. Restoring a snapshot creates a copy of the selected world, leaving the current files untouched. Snapshot pruning and retention policies help manage backups, which can also include mod JARs and configuration files. FastBack works with Minecraft clients and dedicated servers on Linux, Mac, and Windows. It requires native Git and Git LFS to be installed and available on Minecraft's process PATH. The project describes it as intended for worlds up to about 5GB and recommends GitHub remotes only for smaller worlds under 500MB because of GitHub size restrictions. Documentation links to CurseForge for downloads and Discord for questions and help installing native Git. FastBack is distributed under GNU GPL version 2.

FolderRewind is a free Windows application for backing up and restoring files, project data, and game saves. It offers full, smart incremental, and overwrite backups using 7-Zip, with 7z and zip compression and configurable levels, methods, and thread counts. The home page says encrypted backups use AES-256. Automation can run at intervals, on a schedule, at startup, for selected targets, or when conditions are met. FolderRewind uses rclone to transfer local backup chains to cloud storage as an extra redundancy layer; its guide demonstrates OneDrive setup and mentions WebDAV bridges such as OpenList. The official MineRewind extension adds Minecraft save discovery, hot backup and restore, hotkeys, and coordination with the current world. Restoring partial backups forces Overwrite and disables Clean to prevent removing files outside the backup scope. Requirements are Windows 10 version 1809 or later, or Windows 11, on x64 or ARM64. The maker recommends Microsoft Store; MSI is marked beta and MSIX is offered for advanced sideloading.
