A method and device for data backup in a computer room

Abstract

The invention discloses a machine room data backup method and device. The method comprises the steps that management equipment obtains a first incremental log to be sent from a first storage area, andif it is determined that a second storage area does not contain the first incremental log, the first incremental log is sent to a second machine room, so that the second machine room and the first machine room are synchronized. Wherein the first storage area stores increment logs corresponding to the first machine room at all moments, and the second storage area stores increment logs corresponding to the second machine room at all moments. Therefore, on one hand, the storage of the incremental logs by the management equipment cannot be influenced in the data backup process, so that the integrity of the data is guaranteed; And on the other hand, when network abnormity or network fluctuation exists at the entrance and exit of the machine room, it can be guaranteed that data are not lost, after the network of the machine room is recovered or the network condition is improved, data backup can be continuously executed, and the backup time delay under the normal condition is rapidly recovered.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for data backup in a computer room. Background technique [0002] With the development of the Internet, the competition among enterprises has become increasingly fierce. In order to provide more reliable services, more and more enterprises have abandoned the traditional single computer room architecture and adopted the main and backup computer room architecture instead. Usually, the host computer room provides external services, and when the host computer room fails, it switches to the backup computer room and continues to provide external services. In the architecture of the main and standby computer rooms, the key problem is the data backup between the main and standby computer rooms. [0003] One implementation method in the prior art is to solve the above problems by using batch and regular backup. However, this method will inevitably lose data wi...
