Abstract


With the extensive application of information technology in the military field , the military business systems have been destroyed or system failure will cause serious damage , it is extremely important to study military business systems disaster recovery technology . Data disaster recovery technology is the basis of a business disaster recovery , data replication technology can not meet the military business disaster recovery system to become a hot topic in the need for off-site to establish a many-to-many backup systems , based on remote data replication , data disaster recovery technology . Wide geographical distribution of military information networks , involving a range of business , complexity level , the system has a diversity of hardware facilities and software complex structure , a single -level data disaster recovery structure can not meet the military needs of the business system . Should start with key business , designed and implemented in accordance with the different levels , multi- level data disaster recovery structure , to achieve the separation of data and applications , to achieve multi-level storage backup , management and technology solutions . The thesis focuses on the needs of the the military business system cluster disaster recovery , design -based real - time remote IP distribution formula copied backup solution , and remote real-time backup system using existing software simulation designed a T- self ; basis Adapting to the classification of remote mirroring mechanism to achieve a one-to-many replication remote host data ; same time, in order to optimize the performance of complex data disaster recovery network hierarchical replication system , based on application requirements and hardware facilities , operations research methods to determine the response multilayer node tissue shortest time to study the rules at this structure node replication selection strategy ; design a replication set of rules can be customized to meet the different needs of the proposed limits based on the difference between active and standby data update P non - business-critical data replication using adaptive replication mode switching . Finally, the prototype system , test the system to modify application support for database applications and analog blocks and system performance parameters of the testing and analysis .
