CaCl2Backup vs ServerBackup

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.

ServerBackup is a Minecraft server backup plugin for administrators seeking to protect server files and worlds from data loss, griefing, and chunk failures. It schedules backups automatically and offers in-game commands to target a particular world, folder, or file. Those commands can also list and search backups, remove them, and zip or unzip folders. Backup creation runs asynchronously, separately from the server’s main thread. Dynamic Backups are designed to save only world chunks or regions that may have changed. The plugin can upload and download backups through an external FTP server and list remote backups; the maker says transfers use SSL encryption. A configuration setting can delete local backups after upload. Many settings are customizable through config.yml. ServerBackup is free, with Linux and self-hosted platforms listed. The homepage offers version 2.10.0 for Minecraft 1.18 and later, plus an alternate version for earlier releases. SFTP on port 22 does not work with its FTP backup feature.
