Step 4. Select Project, Region and Availability Zone
[This step is available if you have selected the Restore to a new location, or with different settings option at the Restore Mode step of the wizard.]
At the Data Center step of the wizard, select a project, a region and availability zone where the restored Cloud SQL instances will operate. For more information, see the Google Cloud documentation.
If you want to configure the restored Cloud SQL instance for high availability, select the Multiple zones (survives datacenter outage) option. Select a primary and a secondary zone where the restored Cloud SQL instance will be located within the selected region. The high availability configuration allows you to reduce downtime when a zone or the instance becomes unavailable.
This option is not available if a restore point from which you want to restore a Cloud SQL instance was created for the Cloud SQL instance for which high availability was not enabled.
For more information on high availability in Google Cloud, see Google Cloud documentation.
