I don't know if this has changed since 5.1, but at 5.1 and earlier you would 
need to use /usr/openv/netbackup/NET_BUFFER_SZ (yes, SZ) and put a value 
greater than 64KB in there.  It really doesn't matter what you use, unless 
you're going over a LFN, 1048576 will work in most cases.  It's not like making 
it too big is going to hurt anything.  And, contrary to an old rumor, it is not 
nor has it ever been necessary to set this value to the same thing on client 
and server.

Most people won't see any affect at all by doing this (unless you're running 
really old NBU and doing duplication) until they get to about 4x trunked Gb or 
higher.
