MARS Agent slow backup performance

We have a machine being backed up through MARS agent and is working well before, only runs 4-5hrs. But suddenly have experienced long time backup up to 15hrs now. Already checked Microsoft article https://learn.microsoft.com/en-us/azure/backup/backup-azure-troubleshoot-slow-backup-performance-issue#cause-backup-job-running-in-unoptimized-mode but nothing has helped. No relevant event logs can show me what causes this. Is there any other things I can still check to know what causes this issue?

Thank you

    Hi @Faye Entienza ,

    Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.

    CBengine logs will have details on what is causing the backup to run longer. You may analyze the logs from CBEngine.errlog file under C:\Program Files\Microsoft Azure Recovery Services Agent\Temp for pointers on cause.

    Another suggestion I would like to make is to log a support ticket with Azure backup support for deeper investigation of this issue. If you don't have the ability to open a technical support ticket, please let me know I can help you further on this.
