The Data is millions upon millions on 2-5kb files.
So from a Network point, it is just about acceptable. It would be a SAN Media 
Server or Client if they paid for it!
The estimate I gave, wasn't even close to the overall capacity.
It is a 1GB Network. But the environment is running flat-out 24 x 7 - There is 
so much going on.
I can change the Multiplexing.... but it will not help much as the data is 
stored in the most unusual structure!

I did want Flash backups, as I tested this before and got much better 
improvement (much!)

Someone check my math, but 100gb in 2 hours, 50gb/hour, 853mb/hour, or 
14mb/sec. I wonder if the LTO4 is able to slow down to match that rate, while 
that knocks the LTO5 out of streaming?

What sort of network connection does this server have? If it's 1gb/sec, it 
should support faster than 14mb/sec; maybe increase your multiplexing?
