I have a 6TB disk backup that I Aux copy to tape every weekend. My tape library is a TL2000 connected through a 6G sas connection configured with two LTO5 drives. My average tape performance for these Aux copies is 140-150g/hr. I have multiple streams that backup to disk and then spin copies to tape using the aux copy. Of that above mentioned performance that is an average and I can see bursts of up to 500G/hr on occasion but can never maintain a consistent acceptable throughput of 300G/hr or better. I have update to the latest firmware on the drives & library and have seen little perfomance increase. How can I go about getting these numbers increased? I have tried increasing chunk size, drivers etc with no luck. I have a remote media agent that does 411G/hr to a single LTO5 drive in a PV124t library following a similar configure hardware setup.
