When a cluster becomes corrupt you can use Windows Backup or a third party product to restore the configuration. Without a backup, a manual restore must take place which could result in the loss of data. A demonstration of installing the backup software along with what to backup and restore is shown and discussed. By having a good backup of the cluster configuration and data you can restore back to where you were before a server crash or outage occurred.
- [Voiceover] When a cluster becomes corrupt,…you can use Windows Backup or a third-party product…to restore the configuration.…Without a backup, a manual restore must take place,…which could result in the loss of data.…There are two types of restore we can do for a cluster.…One is authoritative, and the other is non-authoritative.…Restoring the node to normal function…but not rolling back the cluster configuration…is called a non-authoritative restore.…In this scenario, the reason you use the backup…is only to restore a damaged node to normal function.…
When the restored node begins functioning…and joins the cluster,…the latest cluster configuration…automatically replicates to that node,…and no further configuration needs to take place.…Rolling back the cluster configuration…to the configuration stored in the backup…is called an authoritative restore.…In this scenario, you have determined…that you want to use the cluster configuration…that is stored on the backup,…not the configuration currently on the cluster nodes,…
