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
The present invention relates to a kind of method that realizes the cloud storage.
Background technology
For many years, the television video program gos deep into the life of affect people's always, and the situation of deepening is gradually arranged.TV station need broadcast many grades of video frequency programs every day, and the workload of its data management is also quite big.Data management comprises reading of file and writes two aspects; Traditional matchmaker of TV station supports data and reads and write and realize as memory device through the hard disk of special preparation; We know; The hard disk cost is higher and reading speed is slower, therefore, causes the data transmission efficiency of whole proposal limited and cost is high.At present; Also there is certain methods to come the virtual disk of analog hard disk driver to come the storage of execute file through RAM; And then realize that data read and write; It is the new equipment of on device stack, creating that but the traditional document system filtration drives, and needs preset a plurality of drivers, and system configuration is complicated, difficult management.In addition, in the ablation process of file, the step of file filter is not set, some illegal files also can be fished in troubled waters, and are written in the database occupying system resources and bring certain potential safety hazard.
Summary of the invention
The objective of the invention is to solve the deficiency of existing TV station's data managing method and cloud memory technology; The method that provides a kind of novel realization cloud to store; Overcoming traditional tv platform matchmaker supports data and reads and write all and realize as memory device that through the hard disk of special preparation data transmission efficiency is limited and cost is high; Traditional document system filtration Drive Structure is complicated, difficult management; In addition, in the ablation process of file, the step of file filter is not set, some illegal files also can be fished in troubled waters, and are written in the database occupying system resources and bring shortcomings such as certain potential safety hazard.
The objective of the invention is to realize through following technical scheme: a kind of method that realizes the cloud storage, it comprises a virtual disk load step, reads file step and a written document step for one, described virtual disk load step may further comprise the steps:
(1) user's login interface is provided on subscriber computer;
(2) on subscriber computer RAM, load a virtual disk;
The described file step of reading may further comprise the steps:
The record of (1) matchmaker being supported database is mapped in the virtual disk with the form of file and file;
(2) with the file operation of Drive Layer on the minifilter interception virtual disk;
(3) accessing database is read to such an extent that the matchmaker supports data message;
Described written document step may further comprise the steps:
(1) sets up a white list that only allows legitimate files to pass through;
(2) with the file operation of Drive Layer on the minifilter interception virtual disk;
(3) according to the white list kill file, only allow legal file to get into, write the matchmaker and support data message;
(4) set up respective record at database.
Minifilter of the present invention is the Filter Manager equipment that Microsoft is created, and minifilter drives according to the establishment of minifilter framework, and is managed by Filter Manager.
A Fliter Manager of the present invention manages a plurality of minifilter drivers, and the context between a plurality of minifilter drivers is confirmed by the value of Altitude.
The invention has the beneficial effects as follows: the storage that comes the virtual disk of analog hard disk driver to come execute file through RAM, and then realize that data read and write, and having replaced traditional hard-disc storage, the speed of transfer of data gets a promotion and has reduced system cost; Adopt the All Files operation of minifilter on Drive Layer interception virtual disk to realize the transparent operation of user to file, simple in structure, bookkeeping is convenient; In the ablation process of file, white list mechanism is set realizes file filter, some illegal files are filtered, and avoid it to be written in the database, have practiced thrift system resource and have also improved system data safety of transmission and reliability.

Embodiment
Further describe technical scheme of the present invention below in conjunction with accompanying drawing: a kind of method that realizes the cloud storage; It comprises a virtual disk load step; Read file step and a written document step for one, as shown in Figure 1, described virtual disk load step may further comprise the steps:
(1) user's login interface is provided on subscriber computer;
(2) on subscriber computer RAM, load a virtual disk;
As shown in Figure 2, the described file step of reading may further comprise the steps:
The record of (1) matchmaker being supported database is mapped in the virtual disk with the form of file and file;
(2) with the file operation of Drive Layer on the minifilter interception virtual disk;
(3) accessing database is read to such an extent that the matchmaker supports data message;
As shown in Figure 3, described written document step may further comprise the steps:
(1) sets up a white list that only allows legitimate files to pass through;
(2) with the file operation of Drive Layer on the minifilter interception virtual disk;
(3) according to the white list kill file, only allow legal file to get into, write the matchmaker and support data message;
(4) set up respective record at database.
