Working With Disk Snapshots
If you want to save a disk's configuration, you can create a snapshot to re-use later.
Please note that you can only create snapshots of persistent disks.
Creating a Snapshot
After configuring your disk, click the start button.
After the disk has started, click Create Snapshot.
A new dialog box will appear. Enter a Snapshot Name. This field can only include lowercase letters, numbers, and single dashes. Click Create.
You'll see the message The snapshot is being created. This process may take a few minutes.
You'll be able to load your snapshot when configuring a disk of the same type (Azure Disk snapshots can only be loaded on other Azure Disks, for example). Click Restore Snapshot, then select a saved configuration from the Snapshot dropdown menu.
Your snapshot will also appear on the Snapshots page.
Deleting a Snapshot
Navigate to your Storage page. In Shapshots, click the delete icon for the snapshot you'd like to remove.
You'll see the message The snapshot is being deleted. This process may take a few minutes. The snapshot's Provisioned Status will display as Deleted. After one hour, the snapshot will be removed from your dashboard.
