Method for realizing cloud storage

Abstract

The invention discloses a method for realizing cloud storage, comprising a virtual disk loading step, a file reading step and a file writing step. The virtual disk loading step comprises the procedures of providing a user login interface and loading a virtual disk; the file reading step comprises the procedure of mapping the record of a medium resource database into the virtual disk, intercepting the operation of files of a driving layer on the virtual disk by using a minifilter, accessing the database, and reading the medium resource data information; and the file writing step comprises the procedures of writing the medium resource data information to be written into the virtual disk into the virtual disk, intercepting the operation of files of the driving layer on the virtual disk by using the minifilter, filtering the medium resource data information according to a white list, and recording legal files into the database. The data can be read and written into the virtual disk, the data transmission speed is high, and the cost is low. Due to the adoption of the white list mechanism, the system resources are saved, and the system data transmission safety and reliability are improved.

Description

technical field [0001] The invention relates to a method for realizing cloud storage. Background technique [0002] Over the years, TV video programs have been deeply affecting people's lives, and there is a trend of gradually deepening. Television stations need to broadcast multiple video programs every day, and the workload of data management is also quite large. Data management includes two aspects of file reading and writing. Traditional TV media data reading and writing are realized through specially prepared hard disks as storage devices. We know that hard disks are expensive and slow to read , thus resulting in limited data transfer efficiency and high cost for the entire scheme. At present, there are also some methods to use RAM to simulate the virtual disk of the hard drive to perform file storage, and then realize data reading and writing, but the traditional file system filter driver creates a new device on the device stack, which needs to be preset Multiple dr...

Problems solved by technology

[0003] The purpose of the present invention is to solve the deficiencies of the existing TV station data management method and cloud storage technology, provide a new method for realizing cloud storage, and overcome the traditional TV station media asset data reading and writing through a specially prepared hard disk as a storage device However, the efficiency of data transmission is limited and the cost is high; the structure of the traditional file system filter driver is complex and difficult to manage; in addition, in the process of writing files, there is no file filtering step, and some illegal files can fish in troubled waters and be Writing to the database takes up system resources and brings certain security risks and other disadvantages
