    NetBackup can not manage drive's hardware compression function. This is managed on OS and driver level - st driver and its device file on most of Unixs, and driver's property on Windows. Check the properties of your drive's driver on Windows Device Manager whether you can set compression on or off. Considering the capacity, enabling both(NBU's software compression and drive's hardware compression) is meaningless. And it is sometimes harmful for backup throughput.

Thanks Teiva but please clear some points

 

Would be Redundant means unused / in de-activated mode ?

 

You mean there is no harm if both left ON thn the TAPE drive will not apply its compression because the backup already compressed by NBU Server ?
