      I am using XOA 5.106.2, I have a large incremental mirror backup running between my primary backup NFS and a remote NFS Remote. Apart from the task in the Backup tab saying it has started, there is no progress information in Tasks, so I have nothing to view on the status.
      It is very frustrating as I don't know how long the job has left. My current job has been running two days. I can confirm from the XOA command line with 'journalctl -f -u xo-server.service' that merges occasionally happen, but what about the actual transfer of data? The Remote NFS has IO load and it is updating the files in the directories for the Mirror-ed data.
      Do I need to look at a different log? Is there any way to see this information in XOA? I thought I read over a year ago that this was to be fixed in XOA 6 but I cannot find any reference to that any more in Google searches or this Forum.
      I can't run backups against the two VMs being mirrored as I get the 'lock error'.

      Before I open a support ticket I thought I would ask here. Can I view the progress/current status of a running Mirror Incremental backup job in the GUI? Do I need to enable some debugging manually?

        Hi,

        1. You can enable "Merge backups synchronously" first, which matters in case you have multiple jobs on the same set of data
        2. I think you should have an XO task about it, but let me ask @florent

          Hi,

          Yes, I have "Merge backups synchronously" enabled on the Local Backups jobs but still get the error as the Mirror Job has a lock on the VM data.

          Error/Message:
          "the writer IncrementalRemoteWriter has failed the step writer.beforeBackup() with error Lock file is already being held. It won't be used anymore in this job execution."
          Start: 2025-07-26 21:17
          End: 2025-07-26 21:17
          Duration: a few seconds
          Error: Lock file is already being held

          Thanks.
