New requirements for clustered file systems, database clusters, and distributed database applications
For a file system or database that is clustered or for database applications that are distributed, NetBackup 8.1 requires that you review the auto-discovered mappings in Host Management. For NetBackup for SQL Server, this requirement also applies to availability groups (AGs). On the Mappings for Approval tab, approve each valid mapping that NetBackup discovered in your environment. This configuration ensures that the hosts in the cluster are recognized as secure hosts and can communicate with the master server. If you only install the NetBackup client on one node in the cluster, then this configuration is not required. Perform this configuration in the Host Management properties on the master server. See the NetBackup Security and Encryption Guide for more information.
The Exchange, SharePoint, and SQL Server agents may require that you configure host information in the Distributed Application Restore Mapping host property on the master server.
When you upgrade your master server to NetBackup 8.1, security requirements now exist that may affect your previous configurations for backups and restores of complex workloads including Exchange Server, SharePoint Server, and SQL Server. For example, a complex workload includes the following:
Exchange DAGs
Exchange clusters
SharePoint Server
SharePoint Server with a clustered back-end SQL Server
SQL Server clusters
SQL Server availability groups (AGs)
SQL Server AGs with a failover cluster instance (FCI)
Veritas recommends that you first attempt your database workload backups with your current configuration. If backups do not succeed, then configure the Distributed Application Restore Mapping host property on the master server. If restores do not succeed, configuring the Distributed Application Restore Mapping should also resolve these issues.
Note that if you chose to configure the Distributed Application Restore Mapping for SQL Server highly available environments, certain previous configuration steps are no longer needed. In this case, the SQL Server agent no longer requires a second policy that contains the cluster or AG node names. For a SQL Server cluster or AG, you also do not need to configure permissions for redirected restores for the cluster or AG nodes.
For new installations of NetBackup 8.1, follow the instructions for your agent in the agent's administrators guide. You must configure the mappings for distributed application restores. You must also review the auto-discovered mappings for the hosts in your environment.
