how many volumes do you have the millions of files spread across?

large files? small files?

how wide is the directory structure?

how many disks (raid groups) are volume(s) spread accross?

how many tape drives are available to the netapp?

are the files largely static?

we can get better throughput with some tricks, but there will be a limit which 
will likely be unacceptable for the backup window

such is the Netapp
