Remote media server on backup network

[Efi_G]

I have an interesting scenario

In a remote site i would like to create a backup network and the clients and media server of that site will have a NIC on that network. i wont all backups from clients to media to go through the backup network.

The caveat is that that the master wont have access to the backup network.

Here is the example

Master

master01 10.10.10.5

Media

media01 10.10.20.5

media01-backup 192.168.1.5

clients

10.10.20.x

192.168.1.x

The master has access to the 10.10.20.x network but not the 192.168.1.x how can i make sure the backups are going to media01-backup?

can this be done with preferred network?

backup Data does not travle between the Master and media server and it send only the Meta data info(catalog info).

so the communication between the master and media server does not make much diffrence even they use backup network or other network...( using the backup network is a fair deal)

so the important thing that we need to consider is, how the Media server communicating with the Clients...?

does the have the good communication with media server over the Backup Network or not...

if they have that is all we need....

make sure the clients in the backup policys is poinng or resoving the backup IP in the media server.. 

for example:-

you have a client 

client1 --> 10.10.20.20   ---> other network

client1-backup --->192.168.1.6   --> backup network

just make sure client1-backup  is specified in the policy and also media server is resolivng the same IP.

----

you can achive this by prefered network by using the name client1-backup in bp.conf of client.

In addition to Nagalla's excellent post, ensure that clients have media01-backup as Server entry.

media01 should have 2 Server entries for itself: 
media01 and media01-backup

Have a look at this TN: 

DOCUMENTATION: How network interfaces are selected in NetBackup 6.x/7.x when there are multiple NICs on a NetBackup host.

the first issue is that cannot create media01-backup as a new media server because the master cannot communicate to it therefor i wont be able to change the storage unit in the policy to point to this IP

Preferred network will do this nicely. You can specify which NIC to use for a network, or even which NIC to use for a single IP address.

[RamNagalla]

that is all fine... you can have the media server configured with media01.

but do make sure  clients in the policy is with client01-backup and media01 is using the backup ip to communicate with clients01-backup.

that will do it.
