Azure Backup: Upgrade your Recovery Services Vault to enable support for large disk backups

6:59 am in Azure, Azure Backup, Cloud, Recovery Services vault by Wim Matthyssen


On March 13, 2018 the Azure Backup team announced the general availability for backup of Azure IaaS Virtual Machines (VMs) with large disks (1 to 4 TB), both managed and unmanaged. At the same time they released a set of other improvements to speed up the overall backup and restore process.

To enable these new features a one-time, one-directional upgrade must be done for every Azure Subscription where you wish to use these enhancements. Good to know is that this VM backup stack upgrade, can be started from any vault in your Subscription and will retain all your existing policies and recovery points.


Upgrade procedure


Open the Azure portal and login with you Azure credentials.

Go to your Recovery Services vault dashboard, on the top of the blade you will need to click the banner which says Support for > 1 TB disk VMs and improvements to backup and restore speed ->. If you do need see a banner, you can open Properties, go to VM backup stack and click Upgrade.



The Upgrade to new VM backup stack blade will open. Click on Upgrade.


The upgrade procedure will start, be aware that this process could take up to two hours.


Have fun backing up Azure VMs with these new enhancements. Till next time!

Azure Backup: Create a Recovery Services vault with Azure PowerShell

A Recovery Services vault is an online storage entity used to backup workloads to the Azure cloud. You can use it to hold backup data for various Azure services such as IaaS VMs (Linux or Windows) and Azure SQL databases, but it can also be used by System Center Data Protection Manager (SCDPM) or Azure Backup Server (MABS v1 and MABS v2) to enable cloud backups.


These days it is quite easy to create or manage a Recovery Services vault through the Azure portal, but it is even faster when you make use of a scripting language like Azure PowerShell to automate the setup. Therefore, below you can find the PowerShell script I mostly use to do all the work for me. You can just copy and paste or you can download the complete script (.ps1) from the Microsoft TechNet gallery.

To use the script, first adjust all variables to your use. Afterwards login into an Azure PowerShell window as an administrator and when asked login with the credentials for your Azure Subscription.

The script will first create a Resource Group and then the Recovery Services vault in your Azure Subscription. At the end, it will also set the storage redundancy for the newly created vault. Keep in mind that you can only use Locally Redundant Storage (LRS) or Geo Redundant Storage (GRS).
