Hey everyone, Jignesh here with your Nerdio Go-Live Engineering team!
Sometimes you may run into a situation where you have an unrecoverable session host that contains files that need to be locally stored (E.g., QuickBooks). There’s not always a straightforward way to do this, but I’ve discovered some steps that might help you to quickly migrate and recover those files if you ever run into this scenario.
You could restore the VM from Backup Center, BUT the VM will not authenticate back into Entra ID, and you'll have issues logging back in as an AVD user. Instead, you can use the steps below to only recover the files you need on a new session host (E.g., QuickBooks, etc.) without needing to restore the whole VM and then troubleshoot identity.
This requires:
- A Desktop Image with current Apps and OS Updates.
- Must spin up new Session Host VM from latest Desktop Image.
Check out these articles for more details on these steps:
In the Azure Portal > Backup Center
- Confirm a new host is created in the host pool in Nerdio.
- Manage > Backup Instances.
- Select the previous Host VM you’d like to restore from.
- Next, you'll see all the Snapshots for that host.
- Click the ellipses (…) to the right of the most recent snapshot.
- Select File Recovery.
- Select the most recent restore point.
- Download the executable.
- This script will mount the disk from recovery point as a local drive on the machine where it is run.
- See this Nerdio KB for further illustration on File Level restore: File level restore as mountable disk
- Run the script on the new AVD host you created in step 1.
- Login to the new host with the admin user that has the "VM Admin Login Role" rights assigned (For more info, see this Microsoft link: Assign VM Admin Login Role
- Drill into the folders and move the specific file(s) required from the mounted recovery drive onto the new Session Host.
- Return to the Backup Center and click "Unmount Disk" when you’re finished.
