File management method and device

Abstract

The invention discloses a file management method and device. The method comprises the steps that after a program file stored in a server is sent to a first client, and when feedback information whichcomes from the first client and is sent due to the fact that the program file is identified as a malicious program file according to an anti-virus program of the first client is received, a mark showing that the program file is the malicious program file is added for the program file. Therefore, the server used for cloud storage does not need to detect whether or not the program file stored in theserver is the malicious program file, but determines whether or not the program file is the malicious program file on the basis of information fed back by the client to which the program file is sent. In this way, the operation that the server detects whether or not the program file stored in the server is the malicious program file can be omitted, a large number of bandwidth resources among severs do not need to be occupied, the operation load of the server used for cloud storage is reduced, and the operation efficiency of the server used for cloud storage is improved.

Description

technical field [0001] The invention relates to data storage technology, in particular to a file management method and device. Background technique [0002] Cloud technology refers to a hosting technology that unifies a series of resources such as hardware, software, and network in a wide area network or a local area network to realize data calculation, storage, processing, and sharing. Cloud storage is a new concept extended and developed from the concept of cloud computing. It refers to the collection of a large number of different types of storage devices in the network through application software through functions such as cluster applications, grid technology, or distributed file systems. A system that works together to provide data storage and business access functions to the outside world. With the development of cloud technology, the dissemination of information has far exceeded people's imagination, and the potential security problems in the process of information ...

AI Technical Summary

Problems solved by technology

Some malicious program files flood in the cloud storage environment, seriously affecting the security of the cloud storage environment

But the server that is used for cloud storage stores a large amount of program files, whether detection program file is malicious program file will take up a large amount of computing resources, and because the server that is used for cloud storage is often a distributed server, so detection program file will Uses a lot of bandwidth resources between servers
