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!
