Problem Description:Automated/Manual backups not working when server is on

Steps to reproduce:

  • Schedule Backup from a trigger
  • Take manual backup
  • Stopping server allows manual backup to occur

Actions taken to resolve so far:

Changed backup size limits and settings
Changed auto backup times
Changed backup values in scheduler
Restarted Server, Amp, and machine
Changed logging level to 0 for debug
Captured full backup error message
Unable to complete backups while server is active, did work in the past

A dev is currently looking things over, thanks for the logs!
