Chrono Vault

# 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 ` — Create snapshot - `/chronovault list ` — List all snapshots - `/chronovault info <id>` — Snapshot details - `/chronovault restore <id> ` — 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
