I can't get Backup Exec 12 to overwrite backup files on our 120Gb RD 1000 catridges. We have two catridges and we do a backup to one of them on a Tuesday and the other on a Friday. What I want is for the backup to automatically overwrite the existing backup files once there is insufficient space left to take the running job. The data size is around 50Gb. I have a removeable backup to disk folder with append and overwrite protection seth to 0 days. I have tried changing the maximum backup file size to various sizes and telling it to 'overwrite recyclable media before scratch media' but whatever I do, when the catridge has insufficient space to complete the job, it asks for another cartridge before it will overwrite the other backup jobs on the current one. can anyone advise what the correct settings hsould be to achieve this? Thanks.
