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.
FolderRewind
FolderRewind is a free Windows application for backing up and restoring files, project data, and game saves. It offers full, smart incremental, and overwrite backups using 7-Zip, with 7z and zip compression and configurable levels, methods, and thread counts. The home page says encrypted backups use AES-256. Automation can run at intervals, on a schedule, at startup, for selected targets, or when conditions are met. FolderRewind uses rclone to transfer local backup chains to cloud storage as an extra redundancy layer; its guide demonstrates OneDrive setup and mentions WebDAV bridges such as OpenList. The official MineRewind extension adds Minecraft save discovery, hot backup and restore, hotkeys, and coordination with the current world. Restoring partial backups forces Overwrite and disables Clean to prevent removing files outside the backup scope. Requirements are Windows 10 version 1809 or later, or Windows 11, on x64 or ARM64. The maker recommends Microsoft Store; MSI is marked beta and MSIX is offered for advanced sideloading.
