If you experience a failure scenario with your Horizon Cloud on Microsoft Azure deployment, the service provides for restoring the deployment without loss of data.
To request a restoration of a Horizon Cloud on Microsoft Azure deployment, file a support request as described in VMware KB article 2006985.
High-Level Overview
Customer data is stored in the deployment's Azure Database for PostgreSQL database. The Microsoft Azure PostgreSQL database is a Microsoft Azure managed service.
As of service release v2111 and pod manifest 3139.x, the configuration information that the deployment needs to connect to that PostgreSQL database is stored in the cloud plane.
Therefore, restoration of the Horizon Cloud on Microsoft Azure deployment involves connecting to the PostgreSQL database, retrieving the customer data stored in the database, and using that data to configure redeployed VMs. Using that data, the deployment is restored to the working state it had just before the failure scenario occurred.
Technical Details
Previously, the pod deployer created a resource group with the name in the pattern vmw-hcs-podID-recovery. This resource group had a storage account that was related to the backup and restore service.
With the current implementation for restoration process, the service has no dependency on keeping data in this type of resource group. The restoration operations use the data stored in the deployment's Azure PostgreSQL database.
Given that the service has no dependency on that resource group from manifest 3139.x onwards, when an update to a pre-3139.x deployment is scheduled and its green build-out created, the existing vmw-hcs-podID-recovery resource group will be deleted at that time.
In the restoration process, the customer data is retrieved from the Azure PostgreSQL database and used to configure redeployed VMs to restore the deployment to its latest working state.
When You Experience a Failure Scenario
You initiate the restoration process for a deployment by filing a support request (SR) as described in VMware KB article 2006985.
The VMware support team will advise you about the procedures as part of providing this overall service.
