[0004] However, in the process of creating a mirror object in the storage device of the cloud data center, on the one hand, because the backup server needs to read the backup copy from the storage device first, and then send the write operation to the storage device to form a mirror object, so Before the cloud disk of the virtual machine is created, a large amount of time has been consumed due to a large number of input-output (Input-Output, IO); storage space, so it will increase the user's storage cost in the cloud data center

The invention discloses a data storage method and a cloud data center. The embodiment of the invention provides a method for realizing data conversion in a cloud data center and a backup server, which can shorten the conversion time of a backup data object and reduce the storage cost of a user in the cloud data center when a cloud disk of a virtual machine is created. The method comprises the steps: enabling a backup server to receive a read request sent by a block storage server, wherein the read request comprises a URL address of a to-be-read virtual mirror image object in the backup server and an address range of target data in the to-be-read virtual mirror image object; according to the URL address of the to-be-read virtual mirror image object in the backup server, obtaining an address mapping bitmap and a storage path of backup data in a backup copy corresponding to the to-be-read virtual mirror image object according to the address range of the target data and the address mapping bitmap and the storage path of the backup data in the backup copy, and obtaining target data from the storage device; and sending the target data to the block storage server. The method is suitable for the technical field of storage.
Description
technical field [0001] The present application relates to the field of storage technology, and in particular, to a method for storing data in a cloud data center and a cloud data center. Background technique [0002] In the current hybrid cloud backup, the data of virtual machines (Virtual Machines, VMs) or physical machines (Physical Machines, PMs) in the data center under the cloud is backed up locally by volume or backed up locally, and then replicated remotely to The low-cost storage device in the cloud data center is restored to a virtual machine (also called a cloud host) in the cloud data center through the backup server in the cloud data center, so as to achieve the purpose of disaster recovery and data backup. [0003] The backup data generated by one backup is called a backup copy, and the backup copy includes multiple backup data objects. An object is the basic unit of data storage in object storage technology, and an object is a combination of file data and a se...
