Note the following when you use NetBackup for SQL in a cluster:
For VCS clusters, the VirtualName attribute under the Veritas Cluster Server resource type, Lanman, is the name of the virtual SQL Server.
For MSCS clusters, the unique SQL Server instances are distinguished by the virtual server name.
You perform a backup or restore with a clustered instance of SQL Server as with a non-clustered instance with two exceptions. The client name or host name is the SQL virtual name or VirtualName and the designated instance is <default>.
