The enviroment has a Windows Server 2003 with 5 removable USB hard drives. I have muliple enviroments with different versoins of backup exec (from 9.1 to 12). The tape is to be switched every day (mon thru fri) and a backup run each evening (mon thru fri). The problem is thier is only one backup each drive. Backup Exec overwrites the last backup instead of creating a new one. Thier will only be one 60GB backup on a 300GB drive. I need the backup to be succesfull even if the person on site forgets to change te backup disk. I do not want to append because I am worried if a file is corrupt it will destroy all of the backups on that drive. What I need is Backup Exec to use free space then overwrite with no append.

Thanks in advance
