I have a setup for a customer whereby a full backup is conducted on a Friday - then Monday through to Thur, differentials are carried out. Now, there is a single media set for these two jobs (I understand that is obviously not the best way, if even a good way, of doing this, but, the customer uninstalled Backup Exec without recording his original setup, but wants it back exactly how he had it, I'm just confirming that a certain event won't occur) which both the Full and Differential will backup to.
Now in terms of the overwriting - the full is set to overwrite the media, since it runs once a week, I always want it to overwrite the previous weeks Full. But the Differentials are too going to the same media set. Now, obviously as they are differentials, I want them to always overwrite the previous days differential, so I have set them to Overwrite media when the job begins.
But, does this mean the Monday Differential will go ahead and start to overwrite the full backup from Friday, or will it not because the Full and Differential are two separate jobs?
