ChronoVault Backup review
A Java-world backup mod with granular recovery, cloud sync, and configurable retention.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ChronoVault Backup is an open-source Fabric mod for backing up Minecraft Java worlds, aimed at server operators and singleplayer users who want detailed recovery options. It captures changes when chunks are saved, then uses SHA-256 deduplication and Zstd compression to store new data. A built-in web dashboard brings snapshots, restores, audit information, and configuration together. The listing specifies Minecraft 1.21.11 and support for both server-side and singleplayer environments.
Recovery granularity is its clearest distinction. Operators can restore a region without restarting the server or roll back selected chunks from snapshots; the dashboard also supports section-level snapshot comparison and live block-event auditing. That makes the tool a fit when recovering a particular area matters more than restoring an entire world from a scheduled archive. Its scope is worlds only, however, so teams seeking protection for plugins, configuration files, or other server data should look elsewhere or pair it with another backup method.
Storage and retention are flexible for a self-hosted mod: ChronoVault supports S3 and WebDAV sync, configurable layered retention, and optional cloud offload. Discord, Slack, and Feishu webhooks can send notifications. The project is open source under the MIT license and has a free plan; the published listing does not provide a tier comparison. Choose it for Java worlds when chunk-level rollback, hot region recovery, and control over storage destinations matter. It is not the right fit for Bedrock servers or buyers seeking a managed service or whole-server backup.
ChronoVault Backup pros and cons
- Where it wins
- Captures saved chunks incrementally with SHA-256 deduplication and Zstd compression
- Restores regions without restarting and rolls back selected chunks
- Syncs to S3 or WebDAV with configurable retention and cloud offload
- Where it doesn't
- Backs up worlds only, not other server files
- Requires self-hosted deployment rather than a managed backup service
- Targets Minecraft Java, so it does not fit Bedrock worlds
