Method for implementing multisystem disaster recovery back-up system based on extended CIMXML (common information model/extensible markup language)

A method for implementing a multisystem disaster recovery back-up system based on extended CIMXML comprises the stages as follows: establishing main system models; unifying the main system models; establishing back-up system base models; guiding back-up systems into the main system models; realizing synchronization of main systems and back-up systems; and synchronously updating main system models, patterns and operational data of the main systems between the main systems and the back-up systems and the like. The method has the benefits as follows: the method follows the IEC61970 standard, and a grid model is based on CIM/XML, so that standardization, openness and extendibility of disaster recovery back-up system construction are guaranteed; patterns based on an SVG/XML (scalable vector graphics/extensible markup language) standard are adopted, so that consistency of monitoring screens of the disaster recovery back-up system and the main systems is guaranteed; and on the basis of an SOA (service oriented architecture) design idea, a Web Service technology is adopted to realize automatic synchronization of data such as the models, the patterns and the operation and the like of the main systems and the back-up systems, and zero maintenance of the disaster recovery back-up system is realized.
