BtrBack review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

BtrBack is an open-source Fabric mod for Minecraft Java servers that creates local backups from Btrfs subvolume snapshots. It is designed for administrators running self-hosted Linux servers where the server directory is stored on Btrfs. Backups can be created manually with the `/btrback` command or scheduled using configurable day, hour, and minute intervals. Its scope is the full server, making it a focused option for snapshot-based server protection rather than a general file backup tool.

The standout feature is the combination of retention and rollback controls. BtrBack can purge snapshots automatically after a configured age, while `backups.json` records backup and rollback snapshots in JSON format. Administrators can select a snapshot for a manual rollback, and the mod creates a rescue snapshot before replacing the current server subvolume. This gives the workflow a defined recovery sequence: preserve the current state, select a prior full-server snapshot, and restore it through the mod's rollback process. LuckPerms integration adds command-level permission control.

Platform fit is narrow by design. BtrBack integrates with Fabric, Cloth Config, and LuckPerms, and the verified project target is Fabric/Minecraft 1.18.x with Java 17. It also depends on Btrfs-backed storage and keeps backups local, so it suits Linux operators who already use that filesystem and do not need a broader storage or cloud ecosystem. Choose BtrBack for scheduled full-server snapshots, age-based cleanup, and rollback on a Btrfs-based Fabric server. Choose another approach if you need support for other server platforms, newer Minecraft targets, non-Btrfs storage, or file-level restoration.

BtrBack pros and cons

• Where it wins
  • Scheduled full-server snapshots with configurable intervals
  • Age-based purging and custom retention controls
  • Rollback, rescue snapshots, JSON records, and LuckPerms permissions
• Where it doesn't
  • Requires a Btrfs-backed server directory
  • Targets Fabric and Minecraft 1.18.x with Java 17
  • Restores full server snapshots rather than individual files
