Fix "No Space Left On Device" on Project Zomboid Server

After your Project Zomboid server has been running for a while, you will begin to see this issue when you attempt to start your server.

LOG : General> Start making backup to: /home/container/.cache/backups/startup 
ERROR: General> java.util.concurrent.ExecutionException: java.io.IOException: No space left on device

This error is caused by having too many files open at one time during the backup due to the way the world is saved. For example, most Project Zomboid saves have more than 20,000 files when first starting and mods just increase this number.

The fix to resolve this issue is easy:

Go to the AleForge Panel
Open File Manager
Navigate to your config file on the path .cache/Server
Open your config file. By default, it is named dedicated.ini. If you changed the SERVER NAME on the Startup page, use this name instead.
Find the line that says BackupsOnStart=true and change this to BackupsOnStart=false
Click Save Content
Start your server
