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 realizing cloud and store.
Background technology
For many years, television video program deeply affects the life of people always, and has the situation of deepening gradually.TV station needs to broadcast many grades of video frequency programs every day, and the workload of its data management is also quite large.Data management comprises reading and write two aspects of file, traditional TV station matchmaker provides digital independent and write is all realized as memory device by the hard disk prepared specially, we know, hard disk cost is higher and reading speed is slower, therefore, cause that the data transmission efficiency of whole scheme is limited and cost is high.At present, also certain methods is had to carry out the storage of execute file by the virtual disk that RAM carrys out analog hard disk driver, and then realize digital independent and write, but traditional file system filter driver is the equipment that establishment one is new in device stack, need default multiple driver, system configuration complexity, difficult management.In addition, in the ablation process of file, do not arrange the step of file filter, some illegal files also can be fished in troubled waters, and are written in database, occupying system resources and bring certain potential safety hazard.
Summary of the invention
The object of the invention is to the deficiency solving existing TV station data managing method and cloud memory technology, a kind of novel method realizing cloud storage is provided, overcome traditional electrical television stations matchmaker provide digital independent and write all realized as memory device by the hard disk prepared specially, data transmission efficiency is limited and cost is high; Traditional file system filter driver complex structure, difficult management; In addition, in the ablation process of file, do not arrange the step of file filter, some illegal files also can be fished in troubled waters, and are written in database, occupying system resources and bring the shortcomings such as certain potential safety hazard.
The object of the invention is to be achieved through the following technical solutions: a kind of method realizing cloud and store, it comprises a virtual disk load step, and read Files step and a written document step for one, described virtual disk load step comprises the following steps:
(1) user's login interface is provided on subscriber computer;
(2) on subscriber computer RAM, a virtual disk is loaded;
Described Files step of reading comprises the following steps:
(1) record matchmaker being provided database is mapped in virtual disk with the form of file and file;
(2) file operation virtual disk driving layer is tackled with minifilter;
(3) accessing database, reads matchmaker provides data message;
Described written document step comprises the following steps:
(1) white list only allowing legitimate files to pass through is set up;
(2) file operation virtual disk driving layer is tackled with minifilter;
(3) according to white list kill file, only allow legal file to enter, write matchmaker provides data message;
(4) in Database respective record.
Minifilter of the present invention is the Filter Manager equipment that Microsoft creates, and drives, and managed by Filter Manager according to minifilter framework establishment minifilter.
A Fliter Manager of the present invention manages multiple minifilter driver, and the context between multiple minifilter driver is determined by the value of Altitude.
The invention has the beneficial effects as follows: the virtual disk carrying out analog hard disk driver by RAM carrys out the storage of execute file, and then realizes digital independent and write, and instead of traditional hard-disc storage, the speed of transfer of data gets a promotion and reduces system cost; Adopt the All Files operation that minifilter is driving layer to tackle on virtual disk to realize the transparent operation of user to file, structure is simple, bookkeeping is convenient; In the ablation process of file, arrange white list mechanism and realize file filter, some illegal files are filtered, and avoid it to be written in database, have saved the safety and reliability that system resource also improves system data transmission.

Embodiment
Technical scheme of the present invention is further described: a kind of method realizing cloud and store below in conjunction with accompanying drawing, it comprises a virtual disk load step, read Files step and a written document step for one, as shown in Figure 1, described virtual disk load step comprises the following steps:
(1) user's login interface is provided on subscriber computer;
(2) on subscriber computer RAM, a virtual disk is loaded;
As shown in Figure 2, described Files step of reading comprises the following steps:
(1) record matchmaker being provided database is mapped in virtual disk with the form of file and file;
(2) file operation virtual disk driving layer is tackled with minifilter;
(3) accessing database, reads matchmaker provides data message;
As shown in Figure 3, described written document step comprises the following steps:
(1) white list only allowing legitimate files to pass through is set up;
(2) file operation virtual disk driving layer is tackled with minifilter;
(3) according to white list kill file, only allow legal file to enter, write matchmaker provides data message;
(4) in Database respective record.
Described minifilter is the Filter Manager equipment that Microsoft creates, drive according to minifilter framework establishment minifilter, and managed by Filter Manager, a Fliter Manager manages multiple minifilter driver, and the context between multiple minifilter driver is determined by the value of Altitude.
