Data caching method of cloud storage system

Abstract

The invention relates to a data caching method of a cloud storage system, belonging to the technical field of computer data storage. The method comprises the steps of: taking a flash disk as a carrier of the cloud storage system, starting a computer from the flash disk and loading an operation system in a system area of the flash disk into a memory of the computer; scanning data block caching files in a local data caching area by the cloud storage system and storing each obtained data block caching file in the memory; capturing the operation commands of an upper application program by the cloud storage system through a virtual file system layer, wherein the operation commands comprise the steps of creating the files, modifying the files, reading the files and deleting the files, and the new data blocks formed after the operation are cached in the local data caching area in file form; and storing the formed new data block caching files to a cloud storage server by a network communication module and obtaining data block caching files from the cloud storage server when the needed data block caching files do not exist in the local data caching area. The method improves the response speed and realizes the access of the cloud storage data under the situation of off-network.

Description

technical field [0001] The invention belongs to the technical field of computer data storage, and in particular relates to a method for caching data in a cloud storage system. Background technique [0002] With the rapid development of information technology, the degree of social informatization is getting higher and higher, and the digital information owned by individuals is also growing explosively. Under this background, storage devices have become an indispensable tool in people's daily life. However, various complicated storage devices also bring many problems, such as how to ensure data consistency between multiple storage devices for individual users, how to ensure the safety and reliability of data stored in all storage devices, and how to solve the limited space of storage devices. Wait. Therefore, how to provide an efficient, easy-to-manage, and dynamically growing storage service has become a hot research topic. [0003] The rapid development of computer network...

Such a strategy has the following obvious disadvantages: 1. Inefficiency in accessing cloud storage data: when the cloud storage system accesses cloud storage services, it needs to download all cloud storage data to the client indiscriminately. Carrying out the corresponding operation makes the user need to spend a lot of time waiting for the download process, and if the user only needs to operate a small file, but has to download all the data from the cloud storage service; 2. It is opaque to the user: the user It is not possible to access cloud storage data like accessing local file system data. You need to open the corresponding cloud storage system every time and perform data synchronization before you can access cloud storage data; 3. It is too sensitive to network status. If cloud storage If a network failure occurs when the system requests data from the cloud storage service, all cloud storage data will be unavailable;
