You can delete automatic snapshot policies that you no longer need. After an automatic snapshot policy is deleted, it is no longer applied to its associated disks. This prevents new redundant snapshots from being created and reduces your snapshot storage costs.
Considerations
Deleting an automatic snapshot policy does not affect existing snapshots.
After an automatic snapshot policy is deleted, automatic snapshots are no longer created for the associated disks.
Procedure
In the top navigation bar, select the region and resource group of the resource that you want to manage.
On the Automatic Snapshot Policies tab, find the policy that you want to delete and click Delete Policy in the Actions column.
In the dialog box that appears, click Confirm.
