Fix: "No Space Left on Device" — Server Won't Start

The Problem

Project Zomboid server automatic backup feature can fill up disk space, preventing the server from starting. The error "No space left on device" appears even if you have disk space remaining, because the in-game backup system has its own storage limit.

Option 1: Reduce Backup Count (Recommended)

1. Go to the Files tab in your panel
2. Navigate to your server settings folder
3. Edit server.ini
4. Find BackupsCount and set it to 3 (keeps 3 most recent backups)
5. Save and restart

Option 2: Disable Automatic Backups

1. Edit server.ini
2. Find BackupsOnStart and BackupsOnVersionChange
3. Set both to false
4. Save and restart the server

Warning: Disabling backups means you have no automatic recovery point. Use the panel Backups tab for manual backups instead.

Option 3: Delete Old Backup Files

1. Go to the Files tab
2. Navigate to your world save folder and find the backup directory
3. Delete older backup files you no longer need
4. Restart the server

Other Disk Space Causes

• Log files — Zomboid servers generate verbose logs. Check the logs folder and delete old ones if they are large
• Check your disk usage in the game panel to confirm how much space is actually used
