RollBack from OS Disk Snapshot in AVD

If a virtual machine (session host) in your AVD environment encounters issues, you can roll back to a previous state using Azure VM snapshots. Follow these steps:

Take a Snapshot (Best practice for the Gold Images)

Steps to Take a Snapshot

1. Go to Azure Portal → Navigate to Virtual Machines.
2. Select the AVD (session host) you want to snapshot.
3. Under Disks, choose the OS Disk.
4. Click Create Snapshot → Fill in details like name and storage type.
5. Click Review + Create → Create Snapshot.

Example– "I created an AVD as a Gold Image to test snapshot rollback. Now, create a folder named ‘Test-snapshot-C-drivefolder’ in the C drive of Vivek-GoldImage to check if the data will lost after rollback."

Select ->Disk

Now we can see the OS Disk details, please select again disk name to expand the details.

To take the snapshot, select the "Create Snapshot"

Fill the details of Snapshot.

Snapshot Type:

Full (Default) -> Best for full backups Stores entire disk contents.

Incremental (Recommended) -> Saves only changed data since last snapshot (cheaper and faster).

Once snapshot created. Create the disk from snapshot.

Fill the details for disk.

Once disk created. Now, we can create the AVD from the disk.

Login to AVD and validated the data after deleted the Original AVD Gold Image.

Now logged in to New AVD, which we created from OS Disk snapshot and validated folder is available.
