Ensure that the Symantec Product Authentication Service is installed and configured.

For complete installation instructions, see the NetBackup Security and Encryption Guide.

To set a longer default time, consult the NetBackup Security and Encryption Guide.

See the NetBackup Security and Encryption Guide for more information on broker hierarchies and how to establish trust relationships between brokers.

Ensure that the system has sufficient swap space and the following directories are not full:
