Backing up your Azure Resource Manager VMs

azurebackup
Azure Backups has been GA for a long time now but not long ago, the folks at Azure just removed the preview tag from the service that handles backing up Resource Manager VMs. I’ve been testing Azure Backup on RM deployments since it was announced in preview and I can say that almost all my tests showed promising results. I’ve encountered a couple of quirk during tests but those were ironed out fast and now that the service is out of preview I can say that Resource Manager VM deployments are the way to go.

In this blog post I will show you how to configure the Azure Recovery Services to back up your Azure VMs and recover them when required.

PowerShell Scripts to add / remove data disks on Azure VMs

First things first. Happy New Year!

So after I finished a long waking up cycle I remembered working on a project that involved migrating some SQL workloads to Azure and those workloads required a high amount of IOPS in order to perform optimally. Now after testing the storage system of the on-premise servers I found that they were capable of delivering about 2000 IOPS which is not much and that was with 15K RPM spindles configured in a RAID 5. Now achieving 2000 IOPS in Azure is very easy from a hardware perspective. On a Standard type of VM, one data disk can offer 500 IOPS so you would need four data disks and then configure a software RAID to stripe the data across all disks. This can be done on Windows using Storage Spaces or MDADM if the operating system is Linux.
