Abstract

The invention provides a disaster recovery method, system and device for a cloud computing center. The method comprises the steps of copying a basic mirror image to a local cloud center and a disaster recovery cloud center; writing incremental data based on the basic mirror image into a local cloud hard disk, wherein the local cloud hard disk is created on the local cloud center; synchronously writing the incremental data into the disaster recovery cloud hard disk; and during first backup, creating a disaster recovery cloud host in the disaster recovery cloud center based on the disaster recovery cloud hard disk and the basic mirror image. Before backup operation is carried out, a shared basic mirror image is subjected to full copy in a local cloud center and a disaster recovery cloud center, and a plurality of cloud hosts are created in the local cloud center based on the basic mirror image. When the disaster recovery cloud center performs first backup, the disaster recovery cloud host is created through the basic mirror image and the disaster recovery cloud hard disk, and in the whole disaster recovery processing process, the basic mirror image is only subjected to single synchronization, so that the data volume of disaster recovery synchronization of the plurality of cloud hosts is greatly reduced, and the bandwidth pressure of the network is reduced.

Description

technical field [0001] The invention relates to the technical field of data protection, in particular to a disaster recovery method, system and device for a cloud computing center. Background technique [0002] Disaster recovery technology is a technical means of data protection. The current disaster recovery technology in the industry is based on remote replication or periodic replication of storage, which is based on the complete copy of data to achieve disaster recovery. This method strongly depends on the capabilities of the underlying storage. [0003] For disaster recovery in cloud computing scenarios, all cloud disk content used by cloud hosts needs to be fully copied to achieve disaster recovery capabilities. Under one cloud computing center, there are often multiple cloud hosts for different businesses. Most of the cloud hosts are extended from the same image. When performing disaster recovery, a large amount of repeated data needs to be copied multiple times. If th...
