Method and device for migrating businesses and disaster recovery system

Abstract

The invention discloses a method, a device and a disaster recovery system, wherein the method and the device are used for migrating an application virtual machine from a source data center to a target data center, so that businesses are rapidly recovered when the data center has a disaster. The method includes the steps: acquiring a specification and network information of the application virtual machine by a data center management server; transmitting a creation instruction for creating an application virtual machine on a target server according to the specification of the application virtual machine to the target data center by the data center management server, and configuring a network for the application virtual machine on the target server according to the network information of the application virtual machine; transmitting a mounting instruction to the target data center by the data center management server; transmitting a starting instruction to the target data center by the data center management server. Once the data center of the businesses including the application virtual machine has catastrophic failure, the businesses can be rapidly migrated to the other data center, and all businesses including the application virtual machine are recovered on the other data center within a short time.

Description

technical field [0001] The invention relates to the field of data disaster recovery, in particular to a service migration method, device and a disaster recovery system. Background technique [0002] A Data Center (DC), also known as a server farm, refers to a facility for housing computer systems and related components, such as telecommunications and storage systems. Data centers typically contain redundant and backup power supplies, redundant data communication connections, environmental controls (such as air conditioning, fire extinguishers), and security equipment, among other things. As far as the data centers established by most communication operators are concerned, once an application system is deployed to a certain data center, the application system will belong to the data center. Once the load of the data center is too high or a catastrophic accident occurs, the service quality of the application system will be degraded or interrupted. In order to avoid such cata...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing disaster recovery technology only solves the problem of pulling up virtual machines at the disaster recovery site, and other problems still require manual intervention

For example, if the arbitration disk that provides the third-party arbitration function is normal, the VIS nodes of the production site and the disaster recovery site are normal but the VIS communication is abnormal, then after the VIS node of the site that successfully preempted the arbitration disk survives, the other site still cannot provide IO after restarting Business access, thus requiring human intervention

For another example, when the arbitration disk fails, the heartbeat between the VISs of the two sites also fails. At this time, if the two sites are restarted, they still cannot access the peer end and the arbitration disk, and cannot provide services to the outside world. At this time, manual work is also required. Forcibly pull up one of the sites and promote the master, and then provide services to the outside world

[0005] In other words, the above-mentioned existing VIS active-active data off-site disaster recovery solution still requires manual intervention to restore the business after the virtual machine is pulled up at the disaster recovery site, and the business recovery through manual intervention takes a long time to recover and cannot well meet the needs of users
