Coordinated Multi-VM Backups
Multi-VM systems like SharePoint really need the same effect as Consistency Groups on a SAN. VMware (sorry, I forget the specific name of the tech) has the ability to take VSS-quiesced VM snapshots on multiple VMs in conjunction with a Consistency Group (LUN) snapshot on the SAN. This is an important foundation of their SRM product, since it provides app-consistent snapshots of all servers in the consistency group at the exact same point in time. If we can get multiple VMs VSS-quiesced at the same point in time, then that would be ideal. It would provide a compelling reason to host multi-server systems on Azure IaaS.
