When a snapshot is deleted, only the data specific to that snapshot is deleted, and the cloud disk from which the snapshot was created will not be affected.
Each snapshot of data provided can independently restore the cloud disk to its data state at that moment. Deleting a snapshot created earlier for a cloud disk does not affect your continued use of a snapshot created later.
When a snapshot is deleted, all data in the snapshot will be deleted, and deleted data is irrecoverable. As the deleted snapshot is irrecoverable, act with caution.

Operation Steps

You may delete snapshots as stated below:
- Single deletion: Click Delete in the row of the snapshot to be deleted.
- Batch deletion: Select all snapshots to be deleted (make sure they are not in task status) and click Delete above the list.
In the Delete Snapshot dialog box, after confirming the information as prompted, click OK.

You can use DeleteSnapshots API to delete snapshots.
