Advanced Backups vs mcwrapper

Advanced Backups is a free, open-source backup mod for Minecraft Java edition, supporting NeoForge, Forge, Fabric and Spigot. It can run entirely on a server; a client installation is needed only to receive backup notifications. The mod supports ZIP, differential and incremental backups, with options for schedules, startup and shutdown backups, and minimum and maximum intervals. Automatic purging can be set by storage size, age or backup count, while command-created snapshots are protected from that cleanup. A command-line tool can restore a whole backup or an individual file and export a backup; it requires Java on the system PATH. The tool can detect backups created by other mods, but it cannot export those backups. Client-side toasts report when backups occur and can be disabled or limited to operators. The README says many Minecraft versions are supported and invites requests for additional versions. The project lists a BSD-3-Clause license, and its backup scope is worlds-only with local storage. One limitation matters for incremental backups: losing a partial backup can damage that chain until the next full backup, and incremental restores take the longest.

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.
