Note the following considerations before you install VERITAS NetBackup and Sun Cluster HA for NetBackup. Figure 1–1 illustrates the configuration limitations.
VERITAS NetBackup is a single-instance data service. You cannot run more than one instance of VERITAS NetBackup per cluster.
You must install NetBackup master servers in a cluster.
NetBackup clients can exist inside of a cluster or outside of a cluster.
You cannot include NetBackup media servers and their backup devices (tape libraries, optical readers, and so on) in any cluster.
The shared disk that is associated with the NetBackup master server should be large enough to accommodate the NetBackup administrative files and logs that accumulate over time. The size of the administrative files and logs depends upon the amount of backup activity that is required for your configuration.
If the NetBackup client is a cluster and if one of the logical hosts on the cluster is configured as the NetBackup client, NetBackup cannot back up the physical hosts.
