When multiple copies are made concurrently, a parent job appears, plus a job for each copy.
The parent job displays the overall status, whereas the copy jobs display the status of a single copy. Viewing the status of individual jobs allows you to troubleshoot jobs individually. For example, if one copy fails but the other copy is successful, or if each copy fails for different reasons. If at least one copy is successful, the status of the parent job is successful. Use the Parent Job ID filter to display the parent Job ID. Use the Copy filter to display the copy number for a particular copy.
The following example shows a backup that contains two copies. The parent job is 19, copy 1 is job 20, and copy 2 is job 21. Copy 1 finished successfully, but copy 2 failed with a 800 status (disk volume cannot be used for more than one copy in the same job). Since at least one copy successfully completed, the parent job displays a successful (0) status.
