the configuration information is sent to the protected server through the real-time copying module, the configuration information of the distributed block storage synchronization engine in the protected server is synchronously updated, and therefore the protected server is connected with the distributed block storage synchronization engine of the position occupying server completely, and real-time copying of disk data can be carried out.
10. The apparatus according to claim 6, wherein the management of the disaster recovery site pair by the user through the management control module includes creation, list query, modification, and deletion of the disaster recovery site pair;
when a disaster tolerant site pair is created, the site pair name, the production data center, the disaster tolerant data center and the information of the virtual private network need to be appointed;
when the disaster tolerance site pair is deleted, whether a disaster tolerance gateway exists under the disaster tolerance site pair needs to be detected, if yes, the fact that a production server in a protection state still exists under the disaster tolerance site pair is indicated, deletion is not allowed, and if not, deletion can be carried out.
