Abstract

The embodiment of the invention discloses a method, a device and a system for data disaster tolerance. The method comprises: configuring disaster tolerance in a plurality of databases in a data accesscontrol layer, wherein the configuration comprises a main database one or more spare databases of the main database, objects to be copied in the main database and access operation types of the objects to be copied in main database and the spare databases, and the data access control layer is between a data access driving layer and an application system; accessing the main database according to the disaster tolerance configuration; and when the access to the main database fails, switching to one of the spare database of the main database. The method, the device and the system can quickly switch to a spare database to continue accessing the database.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for realizing data disaster recovery. Background technique [0002] In recent years, data disaster recovery has become a hot topic in information data construction, and many data disaster recovery technologies have also developed rapidly. Existing data disaster recovery technologies are generally divided into two types, one is to use some data backup technologies provided by the database itself; the other is to perform disaster recovery backup processing from hardware and file systems. [0003] Some data backup technologies provided by the database itself usually mean that the database itself provides a management, monitoring and automatic operation architecture for creating and maintaining one or more backup databases. Generally, at the physical level and logical level, the data consistency of the production and backup databases is main...
