| Purpose | CaCl2Backup is a Minecraft server backup mod designed for Fabric. | mcwrapper is a Minecraft Server wrapper for OSX and Linux that starts and stops servers, sends commands, and performs safe automatic world-data backups. |
| Restore | It restores world saves from backups, and restore operations overwrite the current world save. | The restore action stops the server if needed, backs up current data, copies the selected backup into the world directory and restarts the server if it was running. |
Plans
In their own words
CaCl2Backup
CaCl2Backup is a Fabric mod for backing up Minecraft Java server worlds. It can create backups on an interval, on a daily schedule, or when the server stops, and those triggers can be combined. Backups are written to temporary output, checked with CRC verification, and published only after validation. Automatic cleanup can limit both the number of backups and their age. Operators can use /backup commands to create, list, restore, and delete backups; all commands require OP privileges. Restoring replaces the current world save, with safeguards described for validating level.dat and handling failed swaps. Configuration can be reloaded without restarting the server. Backups are stored locally, and the documented restore granularity is a full backup. Installation requires putting the mod JAR in the server’s mods folder after installing Fabric Loader and Fabric API. The stated requirements are Minecraft 26.0+ in the 26.x series, Fabric Loader 0.15.0+, Fabric API, and Java 25+. The project identifies its license as MIT.
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.
