I have an Exchange 2007 Server that has Backup Exec running on it. The only thing I am using Backup Exec for is to do a GRT backup of the Exchange stores doing a D2D backup to an External USB drive. The drive is large enough to hold 5 backups. What I would like Backup Exec to do is keep backing up until the drive gets full or almost full and then delete the oldest backup to make room for the latest backup. What is happening instead is that it fills up the disk and then I have to manually delete the older backups for it to continue backing up. Is this possible and if so how do I configure it?
Backup Exec Version: 12.0 Rev 1394 with SP2
Size of backed up data: 274GB
Backup to Disk properties
Max size for B2D files: 50GB

Please stay on topic about answering this question and not our backup strategy. There is a lot more to our strategy than just this, and other than this one portion it is working well.
Thank you for your help.
