Sometimes instead of restoring a disk from a certain backup, you might want to create an entirely new storage device from a backup. This can be done with Storage Cloning (see 8.14 from the API Doc).

You can achieve this with the following API request, whose response will give you the details of the created storage – such as its UUID.

POST /1.1/storage/UUID-of-the-backup/clone
    "storage" : {
        "zone" : "fi-hel1",
        "tier" : ”maxiops”,
        "title" : "Clone of a backup disk"
