Embodiment Construction

[0069] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

[0070] In this example, a business system application-level disaster recovery method that can dynamically configure the disaster recovery granularity, the steps include:

[0071] 1. Determine granularity

[0072] 2. Determine the disaster recovery role of the application system

[0073] 3. Determine the working mode between the main and standby application systems

[0074] 4. The master and backup application systems generate a command file interface by calling api to record the size and name of the original business data processed by the application system. (effective when the character is the main center)

[0075] 5. The main and standby application systems generate an index file interface to record the results of the application system processing business data by calling the api, including correct, wrong, invalid and other processing results. ...

Abstract

A business system application level disaster tolerance method capable of dynamically configuring disaster tolerance granularity comprises steps of 1) first establishing two application systems; 2) determining whether the role of the application systems is primary or backup application system according to the disaster tolerance granularity; 3) then determining the processing relation between the primary application system and the backup application system according to arbitration, wherein the relation between the primary application system and the backup application system can be automaticallymodified. The invention has the beneficial effects that RTO recovery time is less than 10min and RTP lost production data is approximate to zero, thus creating tremendous social values.

Description

technical field [0001] The invention relates to a method for simultaneous backup of business processing systems in different geographical areas, especially the synchronization of processing process, data synchronization, consistency, real-time backup of data, especially real-time backup of process data. Background technique [0002] There are two main methods of disaster recovery: [0003] 1. Pure backup method, that is, it is divided into different backup methods from different logical perspectives. For example: full backup, incremental backup, differential backup, hot backup, cold backup, etc. Its advantages include: avoid data disasters caused by disasters, effectively use disaster recovery solutions to quickly and accurately restore business applications in emergency locations; backup frequency is not very high; have backup strategies and manageable cost comparison of automatic backup solutions Low. Its disadvantages include: the replacement of media due to insufficie...
