You can delete automatic snapshot policies that you no longer need. After you delete an automatic snapshot policy, the policy no longer takes effect on all disks that were associated with the policy, and automatic snapshots can no longer be created based on the policy for the disks. The existing snapshots are not affected by the deletion of the policy.

On the Snapshots page, click the Automatic Snapshot Policies tab.
On the Automatic Snapshot Policies tab, find the automatic snapshot policy that you want to delete and click Delete Policy in the Actions column.
