💾 AutoSaveMod [Fabric]

AutoSaveMod is a lightweight, high-performance, server-side mod designed to protect your server's data. It automatically triggers full world saves at regular intervals, preventing any progress loss in the event of unexpected crashes, restarts, or hosting failures.

⚠️ Server-Side Only: This mod is strictly required on the server side. Players do not need to install it on their clients to join!

✨ Features

⚡ Lag-Free Performance: The saving process is optimized and runs smoothly without causing TPS drops or player lag.
🌍 Complete Backup: Securely saves all dimensions, world structures, entities, and player data.
⚙️ Fully Configurable: Easily customize save intervals and broadcast messages to fit your server's needs.
🔄 On-the-Fly Reload: Apply config changes instantly in-game without restarting the entire server.
🔒 Safe Architecture: Built on official Fabric API events to completely eliminate any risk of map corruption.

🛠️ Configuration

Upon the first server startup, the mod will automatically generate a configuration file located at:
../config/autosave_mod.json

Default Settings:

saveIntervalTicks — The time between saves in server ticks (20 ticks = 1 second). Default is 6000 (5 minutes).
startMessage — Custom broadcast message sent to all players when the save starts.
endMessage — Custom broadcast message sent when the world is successfully saved.

💻 Commands

/autosave reload — Instantly reloads the configuration file from the disk and resets the timer. (Requires Operator / OP permissions).

❓ FAQ (Frequently Asked Questions)

Q: Do my players need to install this mod?
A: No. This is a 100% server-side mod. Players with a completely vanilla Minecraft client can join without any issues.

Q: Does this mod create full .zip backups of the world folder?
A: No. This mod triggers the built-in Minecraft world saving mechanism automatically. It overwrites the current world files safely rather than creating external zip archives.

Q: Can I turn off the chat notifications?
A: Yes! Simply leave the startMessage and endMessage fields empty "" in the autosave_mod.json config file.

Q: Will this mod lag my heavily modded server?
A: No. The mod utilizes native Fabric events that execute efficiently, ensuring that even large worlds with many entities save without noticeable gameplay stutter.
