13.5 Configuration backup and restore process

Configuration backup is the process of extracting configuration settings from a clustered
system and writing it to disk. The configuration restore process uses backup configuration
data files for the system to restore a specific system configuration. Restoring the system
configuration is an important part of a complete backup and disaster recovery solution.
Attention: Only the data that describes the system configuration is backed up. You must
back up your application data using the appropriate backup methods.
For complete disaster recovery, regularly back up the business data that is stored on
volumes at the application server level or the host level.
To enable routine maintenance of the IBM Flex System V7000 Storage Node clustered
systems, the configuration settings for each system are stored on each node. If power fails on
a system or if a node in a system is replaced, the system configuration settings are
automatically restored when the repaired node is added to the system. To restore the system
configuration in case of a disaster (if all nodes in a system are lost simultaneously), plan to
back up the system configuration settings to tertiary storage. You can use the configuration
backup functions to back up the system configuration.
