Backup my server

Problem Description

Issue

When I try and backup my server instance I always get an error that says.
Here is the error;

Unable to complete task This task could not be completed: Creating Backup - Galaxy SMP (7613 MB) - State: 3. AMP was unable to backup one or more files. This is typically caused by the application running while taking a backup, but can be caused by multiple issues. Attempt the backup again while the application is stopped if this continues.

Reproduction Steps

  • Find me cause
  • Find the solution
  • How to prevent it from happening again
  • The cause would be some plugin/mod not abiding by Minecraft’s autosave system (AMP runs safe-off while taking a backup)
  • Read the log to find out what file it was
  • Find out what plugin/mod that file is from
