Abstract

The embodiment of the invention provides a file backup method and device. The method is applied to a client, and comprises the steps of obtaining a deconstruction log of the client within backup timeof a preset backup period, wherein a state identifier of a file in a file system of the client is recorded in the deconstruction log, and the state identifier is used for indicating whether a file updating operation occurs in the file within the non-backup time of the preset backup period or not; determining an updated target file of the original file subjected to the file updating operation according to the state identifier, and obtaining a storage identifier of the original file in the deconstruction log; and sending the target file and the storage identifier to a backup end, so as to enablethe backup end to execute a backup operation according to the target file and the storage identifier. According to the method and the device, the problems of long consumed time, complicated process and I / O interface resource waste of a file incremental backup mode in the prior art are solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communications, and in particular to a file backup method and device. Background technique [0002] With the rapid development of information technology, enterprise informatization is becoming more and more important, and the amount of information data is also increasing. Especially in today's environment of rapid development of big data, the order of magnitude of information data of many enterprises has directly increased from TB level (1TB=1024G) to PB level (1PB=1024TB), or even larger. The protection of these information data is usually accomplished by clustering, disaster recovery, and backup. With backup as the final guarantee link, no matter it is a storage area network (Storage Area Network, SAN) network or a local area network (Local Area Network, LAN) network, the pressure is increasing. The combination of full backup and incremental backup of files has become ...
