Sorta true, Darren.

However, since in an NBU env, the master initiates the backup, and theclient 
replies to the interface from which the backup was initiated, youget very good 
load balancing.
Ie, the master server starts the backup via interface-A, the client seesthe 
backup request from interface-A, and then starts transmitting backupdata backup 
to interface-A.
I'm getting almost exactly 50:50 loadbalancing of incoming data on apair of 
GigE NICs.
You will need to have the "interface name" of both NICs in the clients'bp.conf 
files.
However, I'm troubleshooting an issue with hot DB backups that I thinkmight be 
related to ambiguity between the interface names and thehostname.....although I 
think I may be able to resolve it with a DNShunt pool.If that doesn't work, 
then I'll probably have to go withEtherChannel/Suntrunking for the master, 
though I'll probably leave themedia servers as they are.
