BtrBack vs Just Enough Backups

BtrBack is a Minecraft Java server plugin for making and restoring full-server backups with Btrfs snapshots. It stores backups locally, supports scheduled backups, and uses a custom retention policy. Operators install the plugin in the server’s plugins folder and use `/btrback [backup/rollback]` to create a backup or start a rollback. Normal backups appear in the `backupSnapshots` section of `backups.json`. Before a rollback, the plugin also snapshots the current server state and records it under `rollbackSnapshots`, outside the regular backup list. Restoring a backup reboots the server twice: once to restore the saved state and again to start normally. Setup requires placing the server directory in a Btrfs subvolume and mounting the root subvolume with `user_subvol_rm_allowed`. The public repository includes the Good Luck With That Public License, which permits copying, distribution, modification, merging, selling, publishing, and sublicensing at the user’s own risk. The repository page shows no releases and zero open issues. The listed plan is free at free.

Just Enough Backups is a Fabric mod for Java Edition Minecraft that manages server-side world backups through an in-game browser. It supports full, partial, and differential backups, with separate automatic schedules for each type and options to run on server start or stop. The browser can create, rename, delete, restore, search, and filter backups. It prepares restores asynchronously; the server then shuts down so the restore can be applied safely at the next startup.

Retention settings can keep a chosen number of each backup type and optionally cap total backup size per world. Before a backup, the mod checks destination free space and aborts unless it meets twice the current world size plus the configured reserve. Configurable multiple worker threads handle world scanning, ZIP compression, and restore extraction. Mod Menu integration is optional. Dedicated-server settings must be edited in the server configuration file; the client config screen covers only HUD and preview settings. It is free under the MIT License and lists Linux, macOS, and Windows support.
