Hello,
There is a better way, perhaps more then one, i don't have exact 
specifics, but by adding a route entry to TCP settings on 
solaris\linux\windows you should be able to tell where should the backup 
go ( which interface to talk to on the backup server).
Perhaps a firewall rule ?
Perhaps not depending on the DNS server for such an server may be 
better,you may be able to accomplish this by adding host entries and 
configuring networker client in certain way.
Last question, why do you need so many address on one server ?
HTH

The solution that worked for our 7.2 server was to add an entry on the 
*client*
in the /etc/hosts that looked like:

hostname-1-2-3-1.whatever.tld            1.2.3.1
hostname-1-2-3-2.whatever.tld 1.2.3.2

(one for each interface).  The name can be made up - all it cares is that
there *is* an entry in /etc/hosts for that IP address.
