Problems solved by technology

The first method is close to reality, so the verification effect is more real, but because it needs to build a backup center and backup network in advance, it also requires a lot of manpower and material resources to participate, the cost is too high, and the implementation is complicated, so it is often used for disaster recovery drills rather than disaster recovery. Verification

Embodiment Construction

[0078] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0079] The method of the present invention is characterized in that:

[0080] The equipment disaster recovery information system adopts the structure of three centers in two places, including local data center, local backup data center and remote backup data center, and the software, hardware environment and network environment of the three data centers are exactly the same, assuming that there may be failures in the system A component of a fault object is called a fault object. At a moment, a fault object may be in a normal state or a fault state. When the state of all fault objects in the system causes the local data center to fail to provide services normally, it is called this system state is the system failure state, and the time point when this system state is detected for the first time is called the time when the failure occurs; otherwise, the system state...

Abstract

The invention provides a disaster backup information system simulation method based on two places and three centers. A simulated disaster backup information system is built according actual needs of a user. Disaster information system drilling processes, caused by a disaster, such as fault injection, fault repair, fault detection, data center switching and back-switching, data storage, and data validity verification are realized. Three signal states, namely a normal state, a fault state and a center replaced state exist in the system. System signals are utilized to realize disaster backup flow control, cost is lowered, work efficiency is increased, disaster backup data and production data sharing storage are user at the same time, and space is saved.

Description

(1) Technical field [0001] The invention relates to a disaster recovery information system simulation method based on two places and three centers. (2) Background technology [0002] With the continuous development of social information construction, people rely more and more on information systems. Therefore, strengthening the disaster recovery construction of the information system to ensure that the key business and data on the information system can be protected when a disaster occurs, and to achieve the minimum loss and rapid recovery of information system data has received extensive attention. How to verify the construction effect of the disaster recovery information system is the key issue of current research. [0003] At present, there are mainly two ways to verify the disaster recovery information system: the first way is to use the actual environment to build a disaster recovery center and disaster recovery network and conduct actual disaster recovery drills; the ...
