NetBackup status code: 6788
Message: The asynchronous operation returned an unknown error.
Explanation: Some Azure Stack REST operations run asynchronously because the operation cannot be completed quickly.
Operations that create, update, or delete (PUT, PATCH, DELETE) a resource typically return a provisioningState value. When an operation is completed, one of the following four values is returned: succeeded, failed, canceled, inprogress
Recommended Action: If an asynchronous operation fails or returns a canceled error as part if the HTTP response, then the backup operation retries.
You can monitor the status of the asynchronous operation in two different ways. You can determine the correct approach to help you correct the issue by examining the header values that are returned from your original request. Primarily, look for:
Azure-AsyncOperation - The URL for checking the ongoing status of the operation. If your operation returns this value, use it to track the status of the operation.
Retry-After - The number of seconds to wait before the status of the asynchronous operation is checked.
