We do this.  We have to backup on both networks since we have some legacy
machines not on the backup network.

So we have both a master and a master-b name. (question 1)

On the client side, if you push your client installs from your master, your
client will get a copy of the master's bp.conf file.  So just make sure you
have both names listed in your master's bp.conf before you push.  Then edit
the bp.conf file on the client side to remove the production interface name
of the master.  Make sure that the client name in the client bp.conf file is
the backup network name.

We don't use a required interface directive.  But we try to make sure that
the client bp.conf file has only one network to look at.

Subject: [Veritas-bu] Dual homed servers & clients


Hello,

My Master, Media and most clients are dual homed, with a public and a 
backup network. I have a design question.

1. When I install NetBackup 4.5 software on the Master, would I enter 
the host name as Master or Master-b, where the -b is the backup network 
interface name?

2. How about the clients? Would I enter the Master server name as Master 
or Master-b when I install the software on clients?

3. Would I still have to use the REQUIRED_INTERFACE parameter on the 
clients even if I enter Master-b?


Thanks very much
Prasad.
