Given all the coverage of the LinkedIn purchase, you may have missed the latest feature update in Azure: you can now backup data stored on Azure hosted SSD Storage using Azure backup.
Azure Premium storage allows you to provision SSD disks in the cloud – which naturally speeds up I/O operations and improves performance of workloads like SQL Server. Unlike traditional (i.e. spinning disk) storage in Azure, you pay for the disk you provision irrespective of how much you use. Traditional storage is billed based on the amount of storage actually used.
Like just about every feature area in Azure, Premium Storage is an evolving story. Last month, Microsoft announced that you could use Azure Site Recovery to replicate to Premium storage.
The most recent announcement means a VM using Premium Storage for storing VHD and other data can now be backed up with Azure backup. There is some documentation on the Azure documentation site: https://azure.microsoft.com/en-us/documentation/articles/backup-azure-vms-first-look-arm/.
With this updated feature, you can now fully backup any Azure VM, whether V1/ARM irrespective of storage used (spinning disks vs premium SSD storage). You can specify the replication options to enable LRS vs GRS, define the backup goals, set policy and specify what to backup. Backup is pretty straight forward!
