Hello,
The example is for the Host file on the server, the logic is that if you 
have multiple network on your backup server, some clients can be backed up 
using Servers NIC # 1 ( What ever IP that may be) and some clients using 
Servers NIC # 2 ( what ever the ip that may be).
In order for this logic to work the host file on the server should be 
configured with two host entries for your backup server ( this names 
should also be specified on servers alies properties)
i.e
Your backup server is called JUPITER that has two NICS as below
JUPITER=Your backup Server
HOST file should look like this on your server
10.10.10.0      JUPITER                 JUPITER.YOURDOMAIL.COM
20.20.20.0      JUPITERB                JUPITER.YOURDOMAIL.COM
Lets assume that "20.20.20.0" is your interface to talk to firewall 
servers or backup Lan, then any client that you want to backup over that 
interface should 
be configured with " Server Network Interface"  parameter on the client's 
interface, so that backup traffic flows over that interface.
Not sure where it's documented, but its well known method that many of the 
networker admins use when having to direct the traffic over multiple 
lan\firewall interfaces.
HTH

Ok, just to clarify, this is the hosts file that goes on on my NW Backup 
server, or on the client? And "SERVERA" is the client I'm looking to 
backup with "IPA" and "IPB" being the name I designate for the network 
interface of that client? Is this documented anywhere?
