In their own words
FastBack
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.
InstantBackup
InstantBackup is a free Minecraft Java dedicated-server mod for incremental world backups. It uses XXHash64 to detect changes and saves only new or modified files. Identical content is shared between backup versions, and blobs are compressed with ZSTD by a dedicated thread pool. Backups can be run manually, scheduled, or managed through an offline command-line interface after the server shuts down. In-game commands create, list, export, delete, and configure backups; every such command requires OP level 2. Scheduling supports intervals, checks whether players are online, and can exclude Carpet fake players. The mod supports Fabric, Forge, and NeoForge for listed Minecraft versions from 1.18.2 through 1.21.11. The default retention cap is 30 versions, while a setting of zero means unlimited. There is no one-click in-game restore: the recommended route exports a ZIP, stops the server, replaces the world directory, and restarts it. The project is licensed under GPL version 3.0 or later, and its listed 1.0.0-beta release is a pre-release.
