Embodiment Construction

[0045] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] It should be noted in advance that the collection service mentioned in the technical solution of the present invention refers to a link in the data mining technology, which is responsible for collecting data from various data sources. Among them, the collection cluster collects the corresponding data, which can be called collection service.

[0047] A collection cluster refers to a collection of collection servers that divide all collection servers according to the attributes of the collection servers, such as the region of the collection server, operator type, or network operation status. The number of collection clusters is at least two.

[0048] The local backup cluster refers to a collection of servers that store and back up the data collected by the...

Abstract

The invention discloses a data backup method and system. The method comprises the following steps that each acquisition cluster acquires corresponding data and sends the data to each local backup cluster corresponding to the acquisition cluster within a first preset time interval after starting to acquire the data so as to perform local backup; and each acquisition cluster sends the data to a data cluster for storage within a second preset time interval after starting to acquire the corresponding data or within a third preset time interval after each local backup cluster starts to receive the corresponding data. Only each local backup cluster needs to store the data sent by the corresponding acquisition cluster and all data do not need to be stored, so that the backup cost is effectively reduced. The purpose of real-time backup is achieved at the same time. Compared with a conventional mode of collecting data in a unified way and then performing backup, the data backup method has the advantage that the backup time is remarkably shortened, so that the backup time is effectively saved. Finally the problems of relatively long time and relatively high cost of the conventional data backup mode are effectively solved.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data backup method and system. Background technique [0002] At present, data backup usually adopts the backup method of unified collection and centralized backup. That is, after the data is collected uniformly by the collection server, an appropriate time is selected to copy or migrate the data to other backup computer rooms through a dedicated line or offline. If the collection servers are distributed in multiple places, first copy the data of each collection server mobile phone to the central storage point, and then copy to other backup nodes, that is, other backup computer rooms. The above data backup method of unified collection and centralized backup is easy to operate, and the integrity of the backup data is good, and each backup node stores a complete data set. However, it takes a long time to perform backup operations after the centralized collection of data, and the cost...
