Point Master server to seperate backup NIC on client

I am currently having a performance issue with a VM client backup running extreamly slow that is located on a DMZ. For testing purposes and for future rollouts we want to create a Backup network to bypass the firewall to see if that is the issue. We created a second virtual NIC on the VM and gave it an address on the same subnet as the Master. Will I need to alter my host file on the Master to point it to the new NIC and clear the Host Cache with bpclntcmd -clear_host_cache ? Is there a better way to configure a Static route to the new NIC?

    Will you want to be forcing ALL of the NetBackup traffic down one NIC?

    If so you can add

    REQUIRED_INTERFACE = <ip of backup interface of client> in the clients /usr/openv/netbackup/bp.conf

    (or for Windows clients in Host Properties -> Clients -> <double click client> -> Universal Settings > Use specified network interface)

     

    It is preferred to use the PREFERRED_NETWORK directive in the technote I posted earlier, but REQUIRED_INTERFACE is fine if you do not want some traffic for NetBackup down 1 interface and some other traffic routing down another interface.

    Add the new IP of the client to the Master  and any media servers responsible for backing it up?

    That would work. Alternatively you could use the PREFERRED_NETWORK if there are multiple routes to the same host. So the master uses a different network JUST for that client or clients.

    I would just change the IP of the client fon the Master/Media servers myself to the new backup IP

    Thank you, Going forward what would be best practice for clients after we establish a backup network? From what i gather it would be adding a new DNS entry for each server pointing to the second NIC with the backup network address, for example a server is being backed up currently named Anthony1238.xxxx.com, I would make a new Static DNS entry called Anthony1238.xxxx.com.Backup for example that points to the backup network. 

    Would this be the best route or is there a better alternative ?
