7 Days to Die Backups not working

Technical Support
1

OS Name/Version: Ubuntu server 24.04.2 LTS (running on proxmox)

Product Name/Version: AMP 2.6.2

Problem Description: For some reason, backups for 7 days to die don’t work. When I hit the create backup button, it says it’s building file system, but then it just stops and no backup is created. Notably, I’ve tried to designate a datastore on a partition on a different drive as the location for backups, but this problem existed before I set that up, and I also have a Minecraft server instance that I set up to backup to the storage and it works fine. The instance console doesn’t provide any information (because the instance is shut down when I try to create backups) and the deployment log simply acknowledges that I managed a remote instance. What additional information might be helpful for troubleshooting the backup issue?

Steps to reproduce:

  • Step 1: Deploy a 7 Days to Die instance and launch

  • Step 2: Set up a datastore on a separate HDD partition for storing backups by following the steps in the " How to change backup locations" documentation.

  • Step 3: Attempt to create a backup and see it terminate without creating the backup.

Actions taken to resolve so far: Tested the “change backup location” process on a different instance running Minecraft to see if there was an issue with the process. Checked the syntax of my configuration files multiple times.

Check your backup policies in the instance to confirm they are enough to allow backup (eg size)

Ah ha! ChatGPT showed me how to get verbose output in the ssh terminal while attempting to run a backup and it gave me a message stating that the allowed size for individual backups was too small. I increased it an now I can create backups through the web UI. You called it, Greelan! Perhaps the Cube Coders could add some code so that error is output to the web UI when it happens? Would have saved me a lot of time.

Edit: For anyone else who is trying to diagnose issues with backups in the future, here’s what I did. Keep in mind I am running AMP on a Ubuntu server VM. SSH into your AMP server’s parent OS (Or just work directly from the CLI) and put in the following command:

tail -f /home/amp/.ampdata/instances/[InstanceName]/AMP_Logs/*.log

This will give you a verbose output of what AMP is doing and gives a lot of info. Keep this window open while you try to do something in the web UI (In my case, I hit the create backup button) and see what info you get.
