If there is catastrophic data loss and the OEM hardware is still operational, you must redeploy Azure Stack Hub. During redeployment, you must specify the storage location and the credentials that are required to access the infrastructure backups. In this mode, there is no need to specify the services that must be restored. The Infrastructure Backup Controller injects the control plane state as part of the deployment workflow.
If there is catastrophic data loss and the OEM hardware is inoperable, you must redeploy Azure Stack Hub on new hardware. You can do a restore of control plane data at any time after the deployment takes place. However, if the Azure Stack Hub build is more than one version later than the version used in the last backup, restores are not supported.
