In their own words
InstantBackup
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.
mcwrapper
mcwrapper is a free Minecraft server wrapper for Linux, macOS, and other POSIX-compatible systems, intended for server administrators. It can start, stop, restart, and check a server’s status, and send arbitrary commands through a named pipe called command_input. Its backup action temporarily prevents world-data writing while it copies and compresses data, then enables writing again. Backups are timestamped, a latest symlink is created, and the default retention is five backups. The restore action stops the server if needed, saves current data, copies a selected backup into the world directory, and restarts the server if it had been running. Restoring disconnects connected clients because it requires an interruption. The log action follows the server log in real time. The install action downloads the current minecraft_server.jar from Mojang and places it in the configured location. Settings can come from environment variables or mcwrapper.conf files in four documented locations. Installation is available from RubyGems.org with the command gem install mcwrapper. The project provides a README and wiki pages on setup, actions, configuration, and automated backups. It is distributed under the MIT License, which provides the software as-is without warranty.
