I have Backup Exec Ver 9 on W2K3 server. I have a differential job scheduled which throws up a "Do you want to overwrite allocated media" message every time it goes to run a job. The job will run OK when I acknowledge the message but I want to automate it so that this message does not appear. I have checked the job setup which is set to overwrite and I have checked the media set which has overwrite protection set to None - Infinite Dont allow overwrite. I have moved the media to another media set with a 4 week overwrite protection period and also to a third where I have set overwrite proection period to 0 hours. I have tried another Differential tape with the same results so it seems to indicate a problem in the job setup or the Media set but I don't know what it is. I'm sure that it is probably relatively simple but I just cannot see it. Help please!
