Also, with my suggestion you don't need to have 10 different nodes. You can 
have one node.  With resource utilization of 10 I believe you will have up to 4 
producer and 4 consumer threads.  It's been a while since I saw the doc on that 
exact setting to thread count.  If you want more you can set it higher like 30. 
Just remember at some point the available resources on the server will come 
into play so change that setting with care.

My main point was if you can get the data onto 10 logical drives then the TSM 
backup will start seperate producer threads.  When you have all 15,000,000 
files on one drive you get one producer thread running on the whole drive.

Hi Mark,

how can I store any data as filespaces of one node(virtualnode) in that case? I 
don't want to setup 10 different webagents for doing restores.


Thanks
