There could be times when your SCSI tape drive not detected by SQL Server Management Studio. Even when the device is working successfully and you can see that in the device manager. So what do you do? The device is well recognized in the device manager, you have latest drivers installed, that too the drivers are certified from Microsoft. So how are you going to take a backup now?
The solution is simple: use the backup command, instead of the GUI.
To do this, run one of the following statements:
BACKUP DATABASE DatabaseName TO TAPE='TapeDevice' RESTORE DATABASE DatabaseName FROM TAPE='TapeDevice'
The following statements are examples:
BACKUP DATABASE AdventureWorks TO TAPE='\\.\TAPE0' RESTORE DATABASE AdventureWorks FROM TAPE='\\.\TAPE0'
Please note that this applies only to non-USB based tape drives.
