Will it continue to backup if one of the node failed?

I would love to seek your assistance and opinions on this setup. I have two SQL
server nodes clustered using Microsoft Cluster. Version of DB and OS is SQL
2007 and Windows Ent 2008 x64.
On each node, there are two DB instance, DB A and DB B, DB A will be active on
Node 1 and DB B will will be passive mode on Node 1. On Node 2 DB B is active
while DB A is passive. Its kind of a cross active-passive cluster setup.
My question is what is the best approach to backup both DB in a clustered NBU
media server configuration? Can NBU services failover to the other node in case
of disaster and resume backup as per normal?
What you need to do is define a virtual backup address that floats across the
cluster nodes with the database. So, you probably already have something like
dba.systems.example.com. Add dba.backup.example.com and have both addresses
sit in the same cluster group. Then tell NetBackup to back up
dba.backup.example.com.
You would do the same thing for an Exchange or file-serving cluster.
The thing to watch for is the cluster group dependency - you have to determine
if you want the database to transition to the other node if your backup network
goes down and only you can know if that's what you want.
