 ### Configuring Azure Backup temporary disk storage
 
-Each Azure Stack virtual machine comes with temporary disk storage, which is available to the user as volume `D:\`. The local staging area needed by Azure Backup can be configured to reside in `D:\`, and the cache location can be placed on `C:\`. In this way, no storage needs to be carved away from the data disks attached to the Azure Backup Server virtual machine.

 ### Storing backup data on local disk and in Azure
 
-Azure Backup Server stores backup data on Azure disks attached to the virtual machine, for operational recovery. Once the disks and storage space are attached to the virtual machine, Azure Backup Server manages storage for you. The amount of backup data storage depends on the number and size of disks attached to each [Azure Stack virtual machine](/azure-stack/user/azure-stack-storage-overview). Each size of Azure Stack VM has a maximum number of disks that can be attached to the virtual machine. For example, A2 is four disks. A3 is eight disks. A4 is 16 disks. Again, the size and number of disks determines the total backup storage pool.

+Storing backup data in Azure reduces backup infrastructure on Azure Stack Hub. If data is more than five days old, it should be stored in Azure.
 
 To store backup data in Azure, create or use a Recovery Services vault. When preparing to back up the Azure Backup Server workload, you [configure the Recovery Services vault](backup-azure-microsoft-azure-backup.md#create-a-recovery-services-vault). Once configured, each time a backup job runs, a recovery point is created in the vault. Each Recovery Services vault holds up to 9999 recovery points. Depending on the number of recovery points created, and how long they're retained, you can retain backup data for many years. For example, you could create monthly recovery points, and retain them for five years.
 
 ### Scaling deployment
 
 If you want to scale your deployment, you have the following options:
 
-- Scale up - Increase the size of the Azure Backup Server virtual machine from A series to D series, and increase the local storage [per the Azure Stack virtual machine instructions](/azure-stack/user/azure-stack-manage-vm-disks).
+- Scale up - Increase the size of the Azure Backup Server virtual machine from A series to D series, and increase the local storage [per the Azure Stack Hub virtual machine instructions](/azure-stack/user/azure-stack-manage-vm-disks).
 - Offload data - send older data to Azure and retain only the newest data on the storage attached to the Azure Backup Server.
 - Scale out - Add more Azure Backup Servers to protect the workloads.
