Minecraft Backup

Minecraft Backup is a free Linux script for backing up Minecraft server worlds to local storage. It suits administrators who can manage a server and its scheduled jobs; its flexible archive and retention choices are useful, but consistency risks mean it is not a set-and-forget safeguard.

Overview

The script backs up world folders from vanilla Minecraft servers without requiring plugins. It can connect to servers managed with screen or tmux, or use RCON, including Docker RCON. That range suits self-hosted setups, though it assumes comfort with Linux server administration rather than offering a graphical workflow.

Backups can use tar or the restic backend, and the README describes restoring tar archives with tar and restic backups with restic restore. Backups are local and cover worlds only, so this is a focused tool rather than a broader server backup system. It can also send status messages to Minecraft chat, useful for making backup activity visible to players.

Key features

• Scheduling: A cron example supports hourly runs. This gives Linux administrators a way to automate regular backups without a separate scheduler.
• Retention choices: Thin retention keeps the latest 24 hourly and 30 daily backups, then uses remaining space for weekly copies. Alternatively, sequential deletion removes the oldest backup, or deletion can be disabled. The first option balances recent recovery points with longer-term history; the others suit simpler policies or storage managed elsewhere.
• Connection and consistency: Screen and tmux support session-managed servers, while RCON options suit servers with remote control enabled. The project recommends RCON because it waits for the server to confirm that saving has completed. Player data can still become inconsistent with world data during a backup, potentially duplicating or losing items. The README also warns that Minecraft bug MC-217729 can trigger a world save after save-off and cause a backup to fail, so these archives should not be treated as infallible recovery points.
• Requirements: The system needs tar and the selected compression tool; gzip is the default. RCON use also requires xxd, an extra dependency for that safer connection route.
• Docker support: Documentation covers running the script in Docker and using it with the itzg/docker-minecraft-server container and RCON CLI.

Pricing

The Free plan costs nothing and includes the Linux Minecraft server backup script. There is no trial distinction to weigh: the plan is free, and the project has no paid tier described. It supports scheduled backups, local storage, worlds-only scope, full-backup restores, and custom retention. That is a practical fit for individual server operators who can supply and manage their own Linux host and storage; it does not provide a different plan for larger setups.

Platforms

Minecraft Backup runs on Linux and is self-hosted. Its requirements include tar and a compression program, with xxd additionally needed for RCON. The README directs users to download backup.sh from the latest GitHub release. The repository identifies its license as MIT.

Who it's for

Choose it if you run a Linux Minecraft server and want scheduled, local world backups with control over archive format and deletion policy. It is especially suitable for administrators already using screen, tmux, or RCON. Look elsewhere if you need a graphical manager, cloud destination, or a stronger assurance that player and world data will remain synchronized during every backup.

Pros and cons

• Pro: Works with vanilla servers without plugins, avoiding a server-side mod requirement.
• Pro: Tar and restic backends plus three deletion approaches let operators choose a workflow and retention strategy.
• Pro: Cron scheduling and chat status messages make recurring backup activity manageable and visible.
• Con: Player data may diverge from world data during backups, with possible item duplication or loss.
• Con: RCON, the recommended route for safer backups, requires enabling RCON and installing xxd.
• Con: The documented MC-217729 save behavior can make a backup fail even around save-off.

Alternatives

Minecraft Backup Software is the broader category directory for comparing options. Consider InstantBackup if you want a free server mod with Linux, macOS, Windows, and self-hosted platform coverage. Just Enough Backups is another free choice, a server-side Fabric mod available for Linux, macOS, and Windows. Pick CaCl2Backup if a self-hosted Fabric server mod fits, provided your setup meets its Minecraft 26.0+, Fabric Loader 0.15.0+, Fabric API, and Java 25+ requirements.

FolderRewind is a free, open-source option for Windows 10 or 11. FastBack is a free alternative listed for Linux, macOS, and Windows. Chronos Backups is also free and covers Linux, macOS, and Windows. mcwrapper is a free option for Linux and macOS, while Better Backups is a free self-hosted alternative.

Verdict

Minecraft Backup is a sensible choice for Linux server administrators who want free, scheduled local world backups and configurable retention without installing a Minecraft plugin. Its main advantage is that focused flexibility; its main reason to look elsewhere is the risk of inconsistent player and world data, compounded by the documented save-related failure case. Use RCON where possible, and keep another recovery strategy if data integrity is critical.
