Zusammenfassung:	A hard disk snapshot method and apparatus based on Openstack platform. The method includes: initiating a cloud hard disk creation request based on a snapshot, and determining, on the basis of a type of a new cloud hard disk, a second storage backend that is about to accommodate the new cloud hard disk (S101); in response to the second storage backend being different from a first storage backend where an old cloud hard disk that stores the snapshot is located, and mounting the old cloud hard disk on one host machine (S103); creating the new cloud hard disk on the second storage backend on the basis of the type of the new cloud hard disk, and mounting the new cloud hard disk on the host machine (S105); and replicating the snapshot from the old cloud hard disk to the new cloud hard disk through the host machine (S107).
