Snapshots can be deleted in two different ways. An individual snapshot can be deleted, or Snapshots can be deleted in bulk.
Individual Deletion
Locate the snapshot you wish to delete and click on the gear symbol on the far right-hand side.

Click on “Delete this snapshot” from the drop-down menu.

A window will appear asking you to confirm. Click “Yes, delete permanently“.

Bulk Deletion
To delete multiple snapshots at once, click on the box next to Snapshots which will select all of the snapshots. Deselect any snapshots you’d like to keep, and then click on the Delete icon at the bottom of the page.

Click “Yes, delete permanently,” and you’re ready!
