Restoring a Cluster Backup

You must be able to restore a cluster to ts previous version in the case of a failure.

1. Go to Administration > Backup and Restore.
2. Select the Cluster tab.
3. In Cluster Backup History, select the cluster and click Restore.
   The following confirmation message appears:

   Are you sure you want to restore the cluster?

4. Click Yes.
   The cluster restore process may take several minutes to complete. When the restore process is complete, the controller logs you off the web interface automatically.

   ATTENTION

   Do not refresh the controller web interface while the restore process is in progress. Wait for the restore process to complete successfully.
5. Log on to the controller web interface.
   If the web interface displays the message Cluster is out of service. Please try again in a few minutes appears after you log on to the controller web interface, wait for about three minutes. The dashboard will appear shortly. The message appears because the controller is still initializing its processes.
6. Go to Administration > Upgrade, and then check the Current System Information section and verify that all nodes in the cluster have been restored to the previous version and are all in service.
7. Go to Diagnostics > Application Logs, and then under Application Logs & Status check the Health Status column and verify that all of the controller processes are online.
