Ok, I don't have that setting enabled but I could try it. Question: how do you decide 5 GB is an optimal value for your LTO-4 tapes? what value could I put for my LTO-5 tapes? I don't really understand what should be the appropiate value for this directive. I don't know how to tell you how speed is my local disk (spool directory), but is this useful?

By the way, do I really need to change the buffer/block size at the Storage configuration? What buffer/block size should I use? > > > Ralf > ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
