MineBackup

Players use the mb command series in chat to manage world saves directly: create a backup, browse history, restore a save or set a schedule for automatic backups. A restore counts down a configurable number of seconds before it runs, and mb stop, mb cancel or mb confirm let the player skip ahead or cancel it. Real-time messages from the desktop application appear in game chat, reporting whether a backup starts, succeeds or fails.

The mod also supports dedicated servers, where operators browse backups and restore them much as they would on a single-player world, with the work handed to a bundled restart sidecar. The sidecar restarts the server through its own start script once a restore finishes. Hot restore works on dedicated servers and on singleplayer and LAN worlds. The desktop application and the KnotLink service must run for the mod to function, and the mod is required on the server while clients may leave it out. Fabric API is required, and the mod is published for Fabric, Forge and NeoForge, with files for 1.18.2 – 26.3 under the MIT License, which is open source.
