Problem Description

Issue

Hi, Im currently having some issues creating backups for my minecraft server. I have a task setup to run every night and that was working for a while. But then I noticed it was not creating anymore. I figured out that was because the default size limits and backup amounts were set. So I removed those variables (just left the boxes blank guessing it removed any restrictions) and that worked for a night. But now its happening again. I tried also setting max numbers in those fields thinking it didnt like having no values set but no luck still. When I run a manual back it starts the task, says “Creating Backup
Building file list…”
But stops a couple seconds after with no errors that I can find. Any help is much appreciated thanks!

Some things ive tried / checked for:
File storage for the VM - It has plenty of space left
Adjusting the values in the backup settings - Ive tried removing the values and setting really high numbers
Different methods of backups - Ive tried setting new tasks thinking one was gltiched, running it manually

Reproduction Steps

  • Creating & re-creating a scheduled backup task
  • Running manual backups
  • Adjusting the backup settings

Putting a bump here because I’m having the same issue.

Yeah I still have not solved the issue.

Check the backup limit settings to see if the size limit is too low

Size limit max is 20GB for me, Individual is 10GB. Doesn’t really matter cause the backups are usually 2~3 GB at most.

So I JUST was able to get a backup to run, not sure what the exact fix was because I was changing a bunch of settings but ill include a screenshot of my settings that you can try and mimic maybe.

Copied these settings and it’s still not working

You’ll need to browse the instance’s `AMP_Logs` folder from the main panel page to see why the backup is failing. The error is normally supposed to be shown in the web UI, but there’s a bug currently that silences it.

This is the line related to the backup attempt I most recently made. What is this file that cannot be added to the backup archive?
