File processing method and server

Abstract

The embodiment of the invention relates to the technical field of data processing, and discloses a file processing method and a server. In the invention, the file processing method comprises the following steps of recovery and overwriting, wherein the step of recovery comprises the following steps that: when a file to be recovered is in the presence in a disk, adding the file to be recovered intoa pre-established recycle bin, and changing the file to be recovered into a recovered file; and the step of overwriting comprises the following steps that: when a file to be written into the disk is in the presence, judging whether at least one recovered file is in the presence in the recycle bin or not, if a judgment result shows that at least one recovered file is in the presence in the recyclebin, selecting one recovered file from the recycle bin, and writing the file to be written into the selected recovered file in a coverage way. By use of the embodiment, an application layer adopts anoverwriting way to replace existing system recovery so as to realize the reuse of the file which needs to be recovered, so that the problem that a disk IO (Input / Output) load is overhigh since the system is frequently called during system recovery can be effectively avoided, and therefore, caching service performance is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a file processing method and server. Background technique [0002] Caching refers to a technology that stores frequently accessed network content in a system that is closer to the user and has a faster access speed, so as to improve the content access speed. A cache server is a server that stores frequently accessed content. As the scale of the network becomes larger and larger, and the trend of live streaming and on-demand services rises, Internet traffic increases exponentially. The cache server is used to distribute the content of the source site to the node closest to the user, so that the user can obtain the desired content nearby, and improve the response speed and success rate of user access. [0003] The inventor finds that there are at least the following problems in the prior art: the cache files on the cache server are usually la...

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide a file processing method and server. The application layer replaces the existing system recycling with overwriting to realize the reuse of the files to be recycled, thereby effectively avoiding frequent recovery due to system recycling. System calls, resulting in high disk IO load, thereby improving cache service performance
