How do I enable backup for my desktop images?

Applies to: Nerdio Manager for MSP (NMM) v2.3+

A Desktop Image serves as the "golden image" for a Host pool. It is used to create new session hosts or to reimage existing session hosts. A Desktop Image consists of two Azure objects; a VM used to manage the image and the other one is the actual image used to deploy session hosts. You must install the latest Windows updates, application updates or install new apps on the image first and then update the hosts in host pools. In some rare situations, you may need to revert the changes applied to your Desktop Image. When powering on the Image VM through NMM, you can select "Save current image as backup" option. This action will create a copy of the current image and retain it for a specified duration. This will provide an option to "restore" the image and revert any changes.

In this article, let us understand how you can enable backup for your desktop images. Login to NMM portal and click "Manage" option on an existing account:


From the main menu on your account's page, select "Desktop pools":


For an existing desktop image say "sampleTesting1", expand the "Power on" drop-down and select "Set as image" option as shown below:


Check the "Save current image as backup" checkbox to enable backup and click "OK" button:


You can view the status of "Power-off and set as image" task under "Desktop Images tasks" section. The following set of tasks are executed automatically:


Note: Once you select "Save current image as backup" option on a Desktop Image, Azure will retain the existing image as a standalone object and not overwrite it with a new one. However, you won't be able to view or manage this image from NMM, so make sure to delete it manually to avoid Azure storage costs. In order to manage old images, go to Azure portal>Images as shown below:
