Just Enough Backups vs Simple 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.

Simple Backup is a free, open-source utility for Minecraft Java server worlds. It schedules automatic backups at configurable intervals and can save them as ZIP archives, TAR.LZ4 archives, or direct directory copies. Backup jobs run asynchronously, and automatic runs can pause when no players are online. Configuration can cap the number of retained backups and stop a new backup when available disk space is too low. Server operators can start backups manually with commands for a general run, ZIP, LZ4, or directory output; the required permission level is configurable and defaults to level 4. Backups are stored in a `backup` folder in the game directory unless an absolute system path is configured. The mod runs only on the server, requires Fabric API, and lists Fabric and Quilt loader support. ZIP uses deflate level 5, while LZ4 files use `.tar.lz4` and need two extraction steps. Support is provided through a GitHub issue tracker.
