Simon,
Is this 4TB on a single filesystem? I'm guessing not....
how many different drive letters? how big is each?
Is each drive letter on a sparate LUN/RG on the SAN, or do you have a couple of 1TB LUNs that you partition or combine on the host side into what you need.
 
I've got one server here with a single drive letter on a single 2TB LUN (one large volume) that has only about 1.2TB utilized, but it has over 4 million files.
 
Attaching a tape drive will do nothing for that guy.....it just takes forever for NBU to walk the filesystem.
 
Paul

what sort of files are they? We have a SAN Media Server, via fibre, with NBU 5.1 via LTO3 Tapes and get good throughput.
 
Its a Windows box though! But does the job - used to take 42 hours, but now down to 16 hours - approx 4TB - huge mix and match of file sizes. from 2kb to 1mb !
 
No tuning was done, no flashback was implemented.
