i am unable to download the Zip file, I request you to contact support, if you have an active support you can still open a new case. I see this is a job log, we would need both jo log and debug logs.
In backup exec it will not delete the Full backups unless the dependent sets are expired, make sure you have the right retension set for incrementals or diffrentials backups, as far as old backup sets are concerned please try to expire them manually...
as mentioned above did you create an account with the same name as of backup exec service account I.e account under which backup exec services are running...and granted permissions...
