Our verdict on CaCl2Backup
CaCl2Backup is an open-source, server-side Fabric mod for Minecraft Java Edition servers. It is designed for administrators who want automated backups of local world saves rather than a hosted backup service. Backup jobs can run at configurable intervals, at a scheduled daily time, or when the server stops. Manual backup creation is also available, with optional labels for easier identification.
The published project details show a free, MIT-licensed tool with no paid tiers. Its local storage model keeps the workflow focused on self-hosted servers: backups are placed in a local backup folder, while copying them elsewhere for off-site storage is a separate operational step. Retention controls remove older backups by backup count and maximum age, helping administrators manage local storage without manually deleting every file. Compression settings and the backup interval can also be configured.
Recovery is the standout area. CaCl2Backup provides an indexed list for selecting, restoring, and deleting backups, and restoration covers complete world saves. Optional automatic server restart behavior can make the recovery sequence more practical when a restart is needed after restoration. Hot configuration reloads avoid restarting the server just to apply configuration changes. CaCl2Backup fits Java Fabric administrators who want free, automated local world protection with straightforward full-backup recovery. It is less suitable for teams that need hosted storage, built-in off-site replication, support for editions beyond Java, or granular restoration of individual world elements.
