    Rescan repository + recreate job metadata

    If exclusion alone doesn’t work:

    1. Disable the NAS backup job
    2. Rescan the backup repository
    3. Remove the failing share from the job
    4. Re-add it
    5. Re-enable the job

    This rebuilds the NAS container mappings.

    hi ​@Benn 

    The issue could be related attempting to read the .copy_offload folder.

    Please could you try excluding the folder from the job and verify?

    Other check: 

    • Try a rescan of your NAS
    • Verify right permission for the  .copy_offload folder
    • Check hidden snapshots on the NAS

    Let me know!

    I have followed this step, the repairing of metadata completed successfully, however the backup again failed with the same error.
