Embodiment Construction
[0027] The embodiment of the present invention provides a method, device and system for data disaster tolerance, which can achieve the purpose of database disaster tolerance configuration while occupying less hardware and transmission resources.
[0028] See figure 1 , Is a schematic diagram of the composition of an embodiment of a data disaster tolerance system provided by an embodiment of the present invention;
[0029] As shown in the figure, the data disaster recovery system includes:
[0030] A data access control layer 400 and a data access drive layer 500; the data access control layer 400 is between the data access drive layer and the application system;
[0031] The data access control layer 400 includes a data disaster recovery device 4, which is used to perform disaster recovery configuration on multiple databases at the data access control layer. The configuration includes a primary database and one or more standby databases of the primary database. Objects in the database...

The embodiment of the present invention discloses a data disaster recovery method, device and system; the method includes: performing disaster recovery configuration on multiple databases at the data access control layer, the configuration including a master database and one or more master databases The standby database, the object that needs to be backed up in the main database, and the access operation type of the object that needs to be backed up in the main database and the backup database; the data access control layer is between the data access driver layer and the application system Between; perform an access operation on the primary database according to the disaster recovery configuration; when accessing the primary database fails, switch to one of the standby databases that access the primary database. By implementing the embodiment of the present invention, when the access operation to the primary database fails, the backup database can be quickly switched to continue the data access operation.
Description
Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device and system for implementing data disaster tolerance. Background technique [0002] In recent years, data disaster tolerance has become a hot topic in information data construction, and many data disaster tolerance technologies have also developed rapidly. The existing data disaster tolerance technologies are roughly divided into two types, one is to use some data backup technologies provided by the database itself; the other is to perform disaster tolerance backup processing from hardware and file systems. [0003] Some data backup technologies provided by the database itself usually mean that the database itself provides an architecture for management, monitoring, and automatic operation to create and maintain one or more backup databases. Generally, at the physical and logical levels, the data consistency of the production and backup databases is m...
