Hi, First, sorry for sending the message without subject, I guess the human brain is not supposed to to more than one thing at the same time (especially mine ;-) ). I already knew the question of why sending primary tapes offsite will pop up. The only thing that came to my mind was that the library is not big enough to hold copies of all the important storage pools. The customer already uses a DLT-Autochanger as copy destination for some of the primary storage pools. We are currently busy redesigning the implementation. I am sure we will not get the customer convinced to buy a bigger library. So what else could possibly be done to prevent removing tapes from a primary pool? The customer's environment consists of: 1x 3575-L18 with 3x3570 (C-Drives) 1x DLT Autochanger 7 Slots with 70GB per tape Client data is about 800GB
