KBackup-Fabric
Losing hours of progress in Minecraft due to a corrupted world or a server crash is every player's nightmare. Whether you run a small private server for friends or manage a large community, safeguarding your creations is essential. KBackup-Fabric is a powerful, full-featured backup mod designed specifically for the Fabric mod loader, giving you complete control over your world data with minimal effort.
Why Choose KBackup-Fabric for Your Server?
Unlike manual file copying or unreliable scripts, KBackup-Fabric integrates directly into your Minecraft server, offering two distinct backup methods: standard zip compression and incremental backups. This flexibility allows you to balance storage space and restoration speed according to your needs. The mod supports a wide range of Minecraft versions, from 1.14.x all the way through 1.18.x, making it a versatile choice for both legacy and modern servers running on the Fabric loader.
Zip Backups: Complete and Portable
The zip backup feature compresses your entire world folder into a single archive stored in the backups directory. This method is perfect for creating full snapshots that are easy to migrate to another machine or store off-site. While zip backups use more disk space per file, they provide a straightforward, all-in-one solution for complete world preservation.
Incremental Backups: Fast and Efficient
For servers with large worlds or frequent backup schedules, incremental backups are a game-changer. KBackup-Fabric uses an algorithm similar to the one found in the Git version control system, saving only the files that have changed since the last backup. This drastically reduces storage requirements and speeds up the backup process, though restoration may require the entire incremental chain. It is an ideal choice for daily automated backups where disk space is a concern.
How to Install KBackup-Fabric
Getting started with KBackup-Fabric is straightforward. First, ensure you have the Fabric mod loader installed on your server. You will also need the Fabric API, which is a required dependency. Once those are in place, simply download KBackup-Fabric from the official GitHub releases page or through a trusted mod platform. Place the downloaded .jar file into your server's mods folder and restart the server. The mod will automatically generate its configuration and backup directories. For players using the foxygame.net launcher, KBackup-Fabric is available directly in the add-on catalog, allowing a one-click install that handles version compatibility and keeps the mod updated automatically.
Essential Commands and Permissions
KBackup-Fabric is controlled entirely through in-game commands, making it accessible to server operators without needing to access the file system. The base command is /kb, which displays a help menu. Here are the core commands you will use regularly:
/kb backup [name]– Creates a full zip backup. If no name is provided, the current system time is used./kb incbak [name]– Creates an incremental backup, storing only changes since the last backup./kb list– Shows all existing backups./kb restore <backup_name>– Initiates a restoration. This requires a confirmation step to prevent accidents./kb confirm– Confirms the pending restore operation./kb delete <backup_name>– Deletes a specified backup file./kb prev– Selects the most recent backup for quick restoration.
Since version 1.7.0, KBackup-Fabric includes a robust permission system compatible with LuckPerms. By default, only server operators can execute backup and restore commands, but you can fine-tune access for moderators or trusted players using nodes like kb.backup, kb.restore, and kb.list. This ensures your backup strategy remains secure while delegating routine tasks.
Automating Backups and Server Restarts
While KBackup-Fabric does not include a built-in scheduler, you can easily automate backups using external tools like RconJobs. By sending commands via RCON at set intervals, you can create regular zip or incremental backups without manual intervention. For advanced users, the mod supports a special exit code (111) after a successful restore. You can wrap your server start script to detect this code and automatically restart the server, creating a seamless recovery process. Example scripts for Windows and Linux are available on the mod's GitHub repository.
Compatibility and Updates
KBackup-Fabric is actively maintained and supports Minecraft versions 1.14 through 1.18 on the Fabric mod loader. Note that versions prior to 1.3.0-dev are not compatible with newer incremental backup formats, so upgrading from very old releases may require a fresh start. For the latest features and bug fixes, always download KBackup-Fabric from the official GitHub releases page, as updates there are more frequent than on other platforms. The mod is designed to be lightweight and server-side only, meaning players do not need to install anything on their clients to benefit from its protection.
Final Thoughts
KBackup-Fabric is an indispensable tool for any Minecraft server administrator who values data integrity. Its dual backup modes, simple command interface, and permission controls make it suitable for both casual and professional use. By integrating this mod into your server routine, you can focus on building and exploring, knowing that a reliable restore point is always just a command away.
