InstantBackup vs Just Enough Backups

InstantBackup is a free Minecraft Java dedicated-server mod for incremental world backups. It uses XXHash64 to detect changes and saves only new or modified files. Identical content is shared between backup versions, and blobs are compressed with ZSTD by a dedicated thread pool. Backups can be run manually, scheduled, or managed through an offline command-line interface after the server shuts down. In-game commands create, list, export, delete, and configure backups; every such command requires OP level 2. Scheduling supports intervals, checks whether players are online, and can exclude Carpet fake players. The mod supports Fabric, Forge, and NeoForge for listed Minecraft versions from 1.18.2 through 1.21.11. The default retention cap is 30 versions, while a setting of zero means unlimited. There is no one-click in-game restore: the recommended route exports a ZIP, stops the server, replaces the world directory, and restarts it. The project is licensed under GPL version 3.0 or later, and its listed 1.0.0-beta release is a pre-release.

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.
