Sometimes, the primary job may start when the tape job is still running. By default, the primary job has priority. In this case, the tape job terminates with error and no data is written to tape. Select the Prevent this job from being interrupted by primary backup jobs option if you want to give the tape job a higher priority. If this option is selected, the primary job will wait until the tape job finishes. Note that the primary job may start with a significant delay.
