Restoring a cluster using a VM level backup

This section looks at how to restore a failed leader node. When a leader node fails, the cluster can be restored using VM level backups of all nodes. The following is covered in this section:

Prerequisites

Before starting your restore make sure the following prerequisites are met:

Prerequisite	Description
VM Level backups	Ensure you have a VM level back of each node (leader and follower) in your cluster.
No active user connections	Ensure there are no active user connections.
Power off all nodes	Ensure all the nodes (leader and followers) in the cluster have been powered off.

The diagram provides a high-level overview of the process for restoring your PAM Server leader node using the stored VM level backup of each node.

Warning

Before starting your restore make sure that all Prerequisites have been met.

Steps to restore using a VM level backup

The following steps are required to restore a cluster using VM level backups of all cluster nodes:

Restore the VM level backup according to your infrastructure.
Turn on all nodes.

Post restore tasks

Once the VM level backup has successfully deployed, you will need to run through the following tasks before allowing users to logon:

Post upgrade task	Description
Trigger AD audit	Before opening any device connections that use an Active Directory account, an audit needs to be manually triggered on all provisioned Active Directories. You can do this by right clicking the Active Directory on the Manage Active Directory page, and select `Trigger audit` from the menu. This will allow additional fields on the Active Directory account page to be populated.
Check device states	Check device status to ensure they are running successfully.
Check user connections	Check users can connect to devices.
Backup node	Take an Osirium backup of the leader and a VM level backup of all nodes. See Backup & Recovery for further details
Delete old nodes	Delete the old nodes but keep the VM level backup files for auditing requirements.
