Embodiment Construction

[0022] Further describe the technical scheme of the present invention below in conjunction with accompanying drawing: a kind of method for realizing cloud storage, it comprises a virtual disk load step, a read file step and a write file step, such as figure 1 As shown, the described virtual disk loading step includes the following steps:

[0023] (1) Provide a user login interface on the user machine;

[0024] (2) Load a virtual disk on the RAM of the user machine;

[0025] like figure 2 Shown, described reading file step comprises the following steps:

[0026] (1) Map the records of the media database to the virtual disk in the form of files and folders;

[0027] (2) Use minifilter to intercept the file operation of the driver layer on the virtual disk;

[0028] (3) Access the database and read the media data information;

[0029] like image 3 As shown, the described steps of writing files include the following steps:

[0030] (1) Establish a white list that only all...

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...
