FastBack

FastBack is a free Minecraft mod for players and server operators who want incremental backups that can run automatically. It suits modest worlds and installations where native Git and Git LFS are practical to set up. Its strongest case is flexible storage and copy-based restores; its clearest limit is the project’s guidance against using it for very large worlds.

Overview

FastBack saves changed parts of a world between snapshots, which can make maintaining a backup history more practical than repeatedly storing full copies. Backups can run when a world shuts down or after Minecraft autosaves, so routine snapshots do not depend on someone remembering to start them.

A restore creates a separate copy of the chosen snapshot and leaves the current world files untouched. That is a useful safeguard when recovering an earlier state, though the restore is at world level rather than a finer-grained selection. Snapshot pruning and retention policies help manage history, but retained backups still need storage space.

Key features

Destinations and backup scope

Backups can go to local storage, a Git server, or a network volume without a Git server. That range gives operators a choice between a straightforward local copy and remote storage, while the network-volume option avoids requiring Git for that destination. Snapshots can include mod JARs and configuration files as well as worlds, which helps preserve parts of the surrounding setup.

Git requirements and scale

FastBack requires native Git and Git LFS to be installed and available on Minecraft’s process PATH. That is a meaningful setup dependency, particularly for a dedicated server whose runtime environment must also be configured. The project says the mod is designed for worlds up to about 5GB and recommends another backup tool for a 200GB server world. GitHub remotes are recommended only for smaller worlds under 500MB because of GitHub size restrictions; operators with larger worlds should choose another destination or another tool.

Permissions

FastBack supports LuckPerms through the Fabric Permissions API for fine-grained command permissions. This is useful where multiple players or staff members need different command access; it is a narrower benefit for a solo world without permission-management needs.

Pricing

FastBack is free and open source under GNU GPL version 2. Its plan costs nothing and includes scheduled backups, worlds and configs as backup scope, both local and remote storage destinations, world-level restores, and custom retention policies. There is no paid tier or free trial to weigh; the tradeoff for a no-cost tool is accepting its Git and Git LFS setup and the stated world-size guidance.

Platforms

FastBack supports Linux, macOS, and Windows, and the project says it works on both Minecraft clients and dedicated servers. The documentation points to CurseForge for downloads and to Discord for questions and help installing native Git.

Who it's for

FastBack is a good fit for players and server operators with modest worlds who want automated snapshots, a choice of storage destinations, and a restore that preserves the current world files. It is also suited to setups where backups should include mod JARs or configuration files, or where LuckPerms command permissions matter.

It is a poor fit for very large server worlds, especially around the 200GB scale the project advises handling with another tool. It may also be an awkward choice for anyone unable to install native Git and Git LFS into the Minecraft process environment, or for operators planning to use GitHub with worlds at or above the recommended under-500MB range.

Pros and cons

Pros

• Incremental snapshots and automatic runs after autosaves or shutdowns support a regular backup history with less manual work.
• Local, Git-server, and non-Git network-volume destinations offer useful flexibility across different storage setups.
• Restores create a copy and leave current world files untouched, reducing the risk of replacing the active world during recovery.
• Mod JARs, configuration files, pruning, and retention policies extend the backup scope and help manage saved history.

Cons

• Native Git and Git LFS must be installed and present on Minecraft’s process PATH, adding setup work.
• The project’s guidance targets worlds up to about 5GB and advises another tool for a 200GB server world.
• GitHub remotes are recommended only for worlds under 500MB, limiting that destination for larger saves.
• Restores operate at world level, so they do not provide finer-grained recovery.

Verdict

Choose FastBack if you run a modest Minecraft world, can provide Git and Git LFS in the Minecraft process environment, and want scheduled incremental snapshots with flexible destinations and restores that leave the current world intact. Look elsewhere if your world is very large, your GitHub remote would exceed the project’s recommended size, or you need a recovery tool without those native Git dependencies.
