ChronoVault

ChronoVault is a incremental backup mod for Minecraft worlds with deduplication and compression

Content-Addressable Storage

Unlike traditional backup tools that copy entire worlds, ChronoVault uses content-addressable storage (CAS):

How It Works:

• Each 512×512 chunk is hashed with BLAKE3
• Chunks are stored by their hash, not by filename
• Zstd compression is applied to each chunk individually
• A snapshot manifest records which chunks existed at that point in time

Storage Efficiency:

• Incremental saves — Only modified chunks consume new storage
• Cross-snapshot deduplication — Identical chunks are stored once, shared by all snapshots
• Per-world isolation — Each world's objects are stored separately

Features

• Async backups — Non-blocking, runs while you play
• In-game GUI — Browse and restore snapshots without leaving the game
• Auto backup — Schedule automatic snapshots
• Safe restoration — Restores to a new world; original is untouched

Commands

• /chronovault backup [description] — Create snapshot
• /chronovault list [world] — List all snapshots
• /chronovault info <id> — Snapshot details
• /chronovault restore <id> [name] — Restore to new world

How to Restore (GUI)

1. Open the Edit World screen (click "Edit" on a world in the world list)
2. Click "Restore Backups" button
3. Select a snapshot from the list
4. Confirm restoration
5. A new world is created with the restored data
