FastBack

Overview

FastBack is a backup mod for Minecraft Java worlds, suited to players and server operators who want recurring snapshots without repeatedly copying unchanged data. Its incremental approach and choice of local or remote destinations are useful, but it depends on native Git and Git LFS being installed and available to Minecraft.

It works with Minecraft clients and dedicated servers, with separate Fabric and NeoForge downloads. Snapshots can cover worlds, mod jars, and configuration files; restoring one creates a separate world copy rather than replacing the active files. That makes recovery less destructive, though it is a full-snapshot restore rather than a way to roll back individual files.

Key features

Incremental snapshots and destinations

FastBack saves changed portions of a world between snapshots, helping avoid repeated copies of unchanged data. Backups can stay local, go to another Git repository, or use a network drive without a Git server. Remote Git destinations can include services such as GitHub. The flexibility suits users choosing their own storage, but Git and Git LFS are prerequisites rather than optional extras.

Automation and retention

Backups can run when a world shuts down or after Minecraft autosaves, with a configurable minimum interval between automatic runs. This gives players and server operators routine coverage without requiring a fixed schedule. Retention options include daily, fixed-count, GFS, and keeping all snapshots, so users can trade storage use against history depth. Garbage collection may take more than five minutes; for worlds larger than 1 GB, the documentation recommends running git gc directly.

Restore and server controls

A restore produces a separate copy of the selected snapshot and leaves current world files alone, a useful safeguard when checking an older state. On dedicated servers, the /backup command is limited to level 4 operators unless permissions are configured through LuckPerms. A broadcast before a backup starts is enabled by default and can be configured.

Pricing

FastBack is free, with a free plan. There are no paid tiers described; the practical cost is meeting the Git and Git LFS requirements and providing storage for the snapshots.

Platforms

FastBack supports Linux, macOS, and Windows, and runs on Minecraft clients as well as dedicated servers. It targets Minecraft Java Edition and has separate Fabric and NeoForge mod files.

Who it's for

FastBack is a strong fit for Java Edition players and server operators who want automatic incremental snapshots, control over retention, and the option to keep backups locally or off the main machine. Its copy-based restore is appropriate when preserving the current world matters. It is a poor fit for anyone unwilling to install and maintain native Git and Git LFS, or who expects a granular file-by-file restore.

Pros and cons

Pros

• Incremental snapshots save only changed world portions, avoiding repeated full copies.
• Local, Git, and network-drive destinations provide storage choices, including remote backups without a Git server.
• Automatic triggers, configurable wait time, and several retention policies support hands-off backup routines.
• Restoring to a separate copy protects the active world files from direct replacement.

Cons

• Native Git and Git LFS must be installed and on Minecraft's process PATH, adding setup and maintenance overhead.
• Garbage collection can take over five minutes, and worlds larger than 1 GB may call for direct use of git gc.
• Dedicated-server /backup access is restricted to level 4 operators by default unless LuckPerms permissions are configured.

Verdict

Choose FastBack if you want free, automated incremental backups for Minecraft Java worlds and value flexible local or remote storage with restores that preserve the active world. Look elsewhere if the Git and Git LFS setup is unwelcome or you need file-level recovery.
