About the Applications utility
NetBackup displays the instances and availability groups that it discovers in the Applications > Microsoft SQL Server node of the NetBackup Administration Console, along with any instances you add manually. After the instances or replicas are registered, you can build a SQL Server Intelligent Policy. (Note, however, that read-scale availability groups must be discovered manually.)
All instances or replicas that you want backed up as part of a SQL Server Intelligent Policy must be registered with credentials. You can assign credentials to individual SQL Server objects as well as instance groups. If you use instance groups, all the objects in the group use the same credentials setting. You can also configure NetBackup to automatically add new instances or replicas to a group and automatically register them.
DBAs can run nbsqladm on a NetBackup client if the backup administrator authorizes a specific user and host on the master server. See the nbsqladm description in the NetBackup Commands Reference Guide.
When NetBackup discovers a SQL Server host that uses multiple NICs, it adds the host with its NetBackup client name. If you installed the NetBackup client with the public interface name, further configuration is required before you can perform backups.
See Configuring the NetBackup client with the private interface name.
See Configuring backups of SQL Server when you have multiple NICs (SQL Server Intelligent Policies).
For a SQL Server cluster or a SQL Server cluster with multiple NICs, NetBackup adds a single entry or one instance. For a cluster, the host name for that instance is the virtual name of the SQL Server cluster. For a SQL Server cluster with multiple NICs the host name for that instance is the public virtual name of the SQL Server cluster. Further configuration is required both these environments before you can perform backups.
