+      - question: Why VMs with the Storage Spaces direct and Storage Spaces are not supported with the Azure VM Backup? 
+        answer: |    
+          Storage Spaces Direct is not supported since it has data spread across two different virtual machines.
+
+          Storage spaces in a single VM not supported for application consistent VM backup. For application consistent VM backup, VSS freezes the I/O and ensures that disk snapshots are consistent. Storage Spaces can still perform writes in the background, breaking the application consistent guarantee. This can result in a small probability that the backup taken is not application consistent. Today, backup and recovery of VM with storage spaces is not blocked in the product.
