Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] The data backup method and system provided by the embodiments of the present invention can be used in a data backup server. The server may be the server where the data to be backed up is located, that is, the server where the source data is located. Certainly, in the embodiment of the present invention, the data backup server may also be a server independent of the server where the source data is located.

Abstract

The embodiment of the invention discloses a data backup method and system. The method comprises the following steps of building a plurality of thread pools; allocating data belonging to the same data storage catalogue to the same thread pool, wherein each thread pool is used for data back of each catalogue, and the thread in each thread pool is used for different data back in the catalogue. Therefore, the threads are not needed to be frequently built and recycled, the consumption of central processing unit (CPU) resources is reduced, and the data backup performance is improved. Moreover, the plurality of thread pools are used for data backup, the distribution range of concurrent backup data is expanded, the probability of simultaneously backing up a small file set is reduced, and thus, the stability of data back is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a data backup method and system. Background technique [0002] In order to prevent the data in the computer from being lost or damaged, it is necessary to back up the data in the computer, so that when the data is damaged or lost, the backup data can be used to restore it. [0003] There are many current data backup schemes, the main schemes are direct backup and multi-thread backup. The direct backup scheme is simple, but the backup performance is poor. The implementation of the multi-thread solution is usually as follows: each file creates a thread to back up the file. Compared with the direct backup scheme, the backup performance of the multi-thread scheme is improved. [0004] In the process of implementing the present invention, the inventor found that in the current multi-threaded backup method, the number of files is equal to the number of threa...
