  • Azure completed a local server backup with warnings and listed one file with the warning DATA FAILURE 0x80990f91
     - Backups are done correctly, only on some occasions whit this warning  DATA FAILURE 0x80990f91, in  some file. The same files ones that have been successfully backed up without error.

    It was reported in 2016 and was described as a known bug which was being patched. with previous versions.

    I have Agent version 2.0.9145.0

    Someone knows how to correct this.

  • The error "DATA FAILURE 0x80990f91" seems to be agent specific. Upgrading the MARS agent to the latest version will resolve this issue.

    I see that you're running an older version of MARS agent (2.0.9145.0). Please update the agent to version (2.0.9169.0) 

    Let me know the status!

  • Thank you.

    What are the steps or the best practice for updating the agent? Exist some procedure? 

    Once updated the agent has to be reconfigured?

    Waiting for your feedback.

  • Just download the agent from here and run it with elevated permissions. Launch Microsoft Azure Backup console and click on "Microsoft Azure Recovery Services Agent" see the snippet below.
