  • An Azure storage account and container that must belong to the same subscription as the web app. If one has not yet been created, simply enable one by clicking the Storage Account in Backups of Azure Portal, followed by choosing the Storage Account and the Container from the Destination blade.

  • Up to 10GB of website and database content is supported by the Backup and Restore feature. The Operation Logs while report an error if the backup feature cannot proceed.
