Backing up Microsoft Cluster Servers

To protect all data in the cluster, including file shares, databases, and the cluster quorum, back up the following:

Local disks, Shadow Copy Components, and System State on each node. The cluster quorum, which contains recovery information for the cluster and information about changes to the cluster configuration, is included in the System State backup.

See Backing up local disks in a Microsoft cluster.
All shared disks, including the data in the Microsoft Cluster Server folder on the Quorum disk.

See Backing up shared disks in a Microsoft cluster.
Virtual servers, which may contain data or contain applications such as Microsoft SQL Server or Exchange Server. Use Backup Exec database agents to back up databases.

See Backing up database files in a Microsoft cluster.

Note:

For offhost backup jobs that use the hardware provider, the media server and the remote computer must be in different cluster groups. The cluster applications cannot support devices' logical unit numbers (LUNs) that have duplicate signatures and partition layouts, therefore, the snapshots containing the LUNs must be transported to a host, or remote computer, that is outside the cluster.

The Command Line Applet can be used with Backup Exec when Backup Exec is installed in a cluster. The only limitation is that you cannot use the Command Line Applet to specify a device for backup. You can use the Command Line Applet to target a device pool, but not a specific device in that pool.
