Abstract

The invention discloses a disaster tolerance system which comprises a first virtual storage and a second virtual storage. The first virtual storage is positioned at a main data center and is connected with a production host, and the second virtual storage is positioned at a backup data center and is connected with a backup host, wherein the first virtual storage is used for integrating and virtualizing all storage devices of the main data center, and reproducing data on a data volume LUN of the main data center to the second virtual storage; and the second virtual storage is used for integrating and virtualizing all storage devices of the backup data center, carrying out backing-up on the data reproduced by the first virtual storage, and carrying out data recovery to the main data center after the main data center has a fault and is recovered. Application-level disaster tolerance is implemented, disaster backup capacity is improved, and when a production node suffers from a serious disaster and is recovered, the second virtual storage can carry out data recovery on the first virtual storage, a service application is rapidly recovered, and resistance to disaster strike is improved.

Description

technical field [0001] The invention relates to the field of storage disaster recovery, in particular to a disaster recovery system. Background technique [0002] With the development of society and the advancement of technology, the daily work of enterprises and institutions is increasingly dependent on data processing, and the continuity of business systems depends on the stable operation of data center systems. [0003] However, the data center of the business system faces many risks and threats during its operation. If there is no corresponding solution to these risks and threats, once a disaster occurs, data will be lost due to various reasons, which will seriously affect the daily work of enterprises and institutions in a high probability. Especially in some specific failures, such as shared disk failures or computer room failures, business continuity will be greatly affected. [0004] Therefore, how to improve the disaster backup capability of the business system, s...
