Embodiment Construction

[0065] 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.

[0066] In order to improve the efficiency of data backup, each embodiment of the present invention adopts a multi-thread concurrent backup method of at least two threads to improve the efficiency of data backup. When backing up data, the file storing the backup file is called a backup image file. One backup image file can store multiple backup files, and the set of all backup image files involved in a backup process is used as a backup set.

Abstract

An embodiment of the invention provides a backup method and a backup device. The backup method includes that at least two threads are adopted for reading data in at least two backup files; and at least two threads write data in the read backup files into a backup mapping file according to a sequence of time for finishing reading of the data in the backup files. Backup efficiency of the data is improved to some extent.

Description

technical field [0001] The embodiments of the present invention relate to data storage technologies, and in particular, to a backup method and a backup device. Background technique [0002] With the continuous deepening of digitalization, enterprises, organizations and individuals have a deeper understanding of the importance of data protection, and data backup is the most commonly used method for data protection. [0003] In the prior art, each file is backed up in a sequential storage manner, and it is necessary to read the data of the previous file and complete the backup of the data of the previous file before backing up the next file. [0004] However, in the existing backup method, the backup efficiency is not high. Contents of the invention [0005] Embodiments of the present invention provide a backup method and a backup device to improve data backup efficiency. [0006] In the first aspect of the embodiments of the present invention, a backup method is provided,...
