We installed BackupExec 12.5 on Windows 2000 Advanced Server with SP4. At the time of installation the HP Tape device was attached with the backup server and we also able to take backup on that tape device using BackupExec. Now we replaced the Tape Drive with a new HP Tape Drive (the drive model is different with the old one). In the Device Mangater I am able to view the driver, but it is not coming under Device in BackupExec Management Console and that's why we are not able to take backup on that device. Need your help to solve this problem
Also the backup rate is very very slow and for taking backup of 4 GB data it is taking almost 2 hours.
