Just Enough Backups vs Minecraft Backup

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.

Minecraft Backup is a Linux script for backing up Minecraft server world folders. It can create tar archives or use the restic backend, and connects to servers managed with screen or tmux, as well as servers with RCON or Docker RCON enabled. The script works with vanilla servers and does not require plugins. Backups can be scheduled with cron; the README includes an hourly example. For older backups, users can choose no deletion, sequential deletion of the oldest backup, or thin retention. Thin retention keeps the last 24 hourly and 30 daily backups, then uses available space for weekly backups. Backups are stored locally, and restoration uses tar extraction for tar files or restic restore for restic backups. The script can post backup status messages in Minecraft chat. It requires tar and a compression program such as the default gzip; RCON also requires xxd. Player data can become out of sync with world data during backups, potentially duplicating or losing items. RCON is recommended because it waits for the server to confirm saving is complete. The README also warns that Minecraft bug MC-217729 can cause a backup to fail.
