    You need to define a hostname for second IP address.

    NBU needs to resolve hostname to IP address. If there are two IP's for same hostname, how should it know which interface/IP to use for backups?

    See this TN: http://www.symantec.com/docs/TECH54733

    If both network with respective ip address is different. I mean to say how can i backing up a client which is residing in different network from second ip address of master server? Is there any option in netbackup? I am doing in my current backup enviroment using another backup tool. Just wanted to know in netbackup.

    The client must have a route through to the master.

    I suspect the config will be something like this :

    Master has two interfaces.

    master-man

    master-bak

    On the one client, you wish to backup through the 'man' interface, you would specify this interfacte as the SERVER entry in the bp.conf file for this client (or registry if windows).

    Next, add master-man as an alias to master-bak in the EMM DB.

    BUT...

    I suspect the exact details might change depending on what name was used when installing NBU onto the master.

    Each IP address needs a hostname.

    See TN that I've posted above for examples.

    Other way ...

    On the client, you specify SERVER = nbu-bk

    In the hosts file of cliebt you add nbu-bk but with the ip address of the nbu-man interface.

    Think that would work, not done it for ages, sure Marianne with confirm.

    The Master server needs hostnames for each NIC/IP as well as SERVER entries for both hostnames.

    See this example in the TN posted above:

    You can also go through these topics in Troubleshooting Guide:

     

    See “Example of host name and service entries on UNIX master server and client” on page 60.
    See “Example of host name and service entries on UNIX master server and media server” on page 61.
    See “Example of host name and service entries on UNIX PC clients” on page 63.
    See “Example of host name and service entries on UNIX clients in multiple networks” on page 64.
    See “Example of host name and service entries on UNIX server that connects to multiple networks” on page 66.

    What about these option "Use specified network interface" OR "Preferred network." in both Master server and client properties.

    You still need a different hostname for each IP address.

    You will put the hostname for the 'network interface' that you want to use by default in the Host Properties.

    If you do this for the master you will restrict the Master to one IP only.

    See 'Configuring Host Properties' in Admin Guide I for details.

    The other option that I think is to change the ip address of you master server in the host file entries of your client.

    In our enviroment, we are having "Production network" and "Management network". I want to take backup of one of the management client which is having only management network connected. Our backup server is connected to both network having different ip address and same hostname.

    Yes Yogesh, i agree. I believe we need to make an entry of backup server's name and management ip address in client's /etc/hosts file and vice-versa in backup server's /etc/hosts file.
