Advanced Backups vs FastBack

Advanced Backups is a free, open-source backup mod for Minecraft Java edition, supporting NeoForge, Forge, Fabric and Spigot. It can run entirely on a server; a client installation is needed only to receive backup notifications. The mod supports ZIP, differential and incremental backups, with options for schedules, startup and shutdown backups, and minimum and maximum intervals. Automatic purging can be set by storage size, age or backup count, while command-created snapshots are protected from that cleanup. A command-line tool can restore a whole backup or an individual file and export a backup; it requires Java on the system PATH. The tool can detect backups created by other mods, but it cannot export those backups. Client-side toasts report when backups occur and can be disabled or limited to operators. The README says many Minecraft versions are supported and invites requests for additional versions. The project lists a BSD-3-Clause license, and its backup scope is worlds-only with local storage. One limitation matters for incremental backups: losing a partial backup can damage that chain until the next full backup, and incremental restores take the longest.

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.
