You can back up and restore configuration and service data by using the Microsoft Azure Stack Hub Infrastructure Backup Service. Each Azure Stack Hub installation contains an instance of the service. You can use backups that the service creates for the redeployment of the Azure Stack Hub cloud to restore identity, security, and Azure Resource Manager data.
For more information, see Recover data in Azure Stack Hub with the Infrastructure Backup Service on the Microsoft website.
You can enable a backup when you are ready to put your cloud into production. Do not enable backup if you plan to do testing and validation for a long time.
Before you enable the backup service, ensure that you have all the backup requirements in place.
For more information, see What is the Azure Backup service? on the Microsoft website.
