Jobs Failed and sucess : need to retry

Hi,

I am very beginner on Veritas and I think my question would seems stupid.

I have a Netbackup 7.0.1 running on Windows Server 2008.

I have a job (with a differential schedule set up) which failed but one day later it succedded with a full schedule.

Same result but a job failed (with a full scheduled set up) but one day later it succedded with a diff schedule.

Of course, I checked the schedule on the Policies, but my question is :

Do I need to rerun the failed job even if the diff or the full gets an 0 or 1 status code ?

Thank for your help.

Lala.
