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.
