Azure Backup provides a simple, secure and cost-effective solution to back up your Azure Virtual Machines (VMs). Azure VM Scale sets with flexible orchestration model provides a logical grouping of platform-managed virtual machines. Scale sets allow you to create virtual machines using a VM configuration model provided at the time of scale set creation, and the scale set can only manage virtual machines that are implicitly created based on the configuration model. As these configuration models needs protection, Azure Backup now supports backup & restore of Azure VM Scale sets with flexible orchestration model.
