Embodiment Construction

[0022] 1. Basic System Description

[0023] Such as figure 1 , the virtual file system of the present invention comprises 4 modules:

[0024] Operating system file interface: used to respond to the request of the operating system to the file system, including directory listing, deleting files, adding files, creating new directories, deleting directories, modifying file names, etc.

[0025] File split restoration module: used to split files during upload, generate redundant files, and record relevant information to the database. When downloading, take out the fragmentation and redundant information of the file from the database, and restore the fragmentation of the file.

[0026] File information database: records the attributes and fragmentation information of all files, attribute information includes file types,

[0027] Size, generation, modification time and other information. The database also uses a UNIX-like format to record the location of files and folders. For exa...

Abstract

The invention relates to a virtual file system achieving reliability through multi-network-disk redundant storage. The virtual file system comprises an operating system file interface, a file splitting and restoring module, a file information database and an uploading and downloading module. According to the virtual file system, by splitting files, it is guaranteed that complete data do not exist in any network disk, and therefore privacy security is guaranteed; even if a network disk administrator or a hacker gets the files, the files cannot be restored due to file incompletion, in this way, it is guaranteed that privacy is not disclosed, and the privacy security of a user can be guaranteed. On the basis of a redundancy technique, even if partial network disks fail or stop service, the system can still restore the data completely from the remaining network disks, and therefore data reliability is guaranteed.

Description

technical field [0001] The invention relates to a virtual file system which realizes reliability through redundancy of multiple network disks, and belongs to the field of computer information storage. Background technique [0002] With the development of the Internet, people began to use network disks to save their own data, which can be accessed at any time and shared conveniently. This method has many unsafe places, including: the business of the network disk may be interrupted at any time, affecting the continuity of use. The service provider of the network disk may suspend the service for various reasons, resulting in the loss of files. Privacy is threatened, and the administrator of the network disk has the right to obtain all files, and can obtain files involving user privacy at any time. The network disk is easily invaded by hackers, resulting in illegal access to files. [0003] Chinese patent application (201210035947.7), title of invention: a method of using a n...
