Problems solved by technology

[0003] In the prior art, when testing a new application version, the production data of the production system needs to be used. During the test period, the normal operation of the production system needs to be stopped first, and the production system is completed when the production system is in a static state. Disaster backup of production data. The production data of disaster backup can be used as test data for the new application version test system. After the disaster backup process is over, the production system can continue. During the disaster backup period, the normal operation of the production system is seriously affected. Conducive to actual production operations

Abstract

The embodiment of the invention discloses a data backup method and device, wherein the method can comprise the following steps that a data synchronization point is obtained under the condition that the production of a production system is not interrupted, the production data of disaster recovery in a first disc of a disaster recovery system is copied into a second disc of the disaster recovery system; the connection between a main directory and a second data directory of a test system is disconnected; the connection is built for the main directory of the test system and a first data directory in the second disc, so that the goal of reading the first data directory and a data set under the first data directory in the second disc by the test system can be achieved; the data set in the second disc is restored according to a data set amendment record under the data synchronization point in a production system log file, so that the data backup of the production data is obtained in the test system. When the method and the device are adopted, the data backup on the production data can be completed in the test system under the condition of not influencing the normal operation of the production system.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data backup method and device. Background technique [0002] In today's technological society, the application of IT (Information Technology) technology has penetrated into all aspects of our life and work, bringing us convenience and speed that have never been seen in any previous technological revolution. Our dependence on IT systems exceeds any previous technology. However, while the IT system provides the information technology infrastructure for the rapid development of the business, it also brings negative factors that we have never noticed before. For example, due to the high concentration of information and processing, the business operation is overly dependent on the IT system, and will be greatly affected by sudden problems in the IT system, which may even cause the business system to fail to operate normally. Therefore, with the continuous development of IT technology, ...
