Method for caching data on client in cloud storage

Abstract

A method for caching data on a client in cloud storage is disclosed. The method comprises the following steps that: the data is cached in a physical folder under a client root directory and the data is uploaded to the cloud; in a client directory, a database of metadata is established, wherein the metadata comprises data logic file information corresponding to the data; a user acquires the metadata from the database and obtains the data logic file according to the metadata; the corresponding data is obtained through the data logic file from the physical folder or the cloud; logic positions of the data correspond with the cached metadata of the client in a one-to-one manner. By using the method in an embodiment of the invention, a speed for the user to acquire the data can be increased.

Description

technical field [0001] The present invention relates to the technical field of storage, and more specifically, to a method for caching data at a client in cloud storage. Background technique [0002] Cloud storage is an extension and development of the concept of cloud computing. It refers to the collection of a large number of different types of storage devices in the network through application software to work together through functions such as cluster applications, grid technology, and distributed file systems. A system that jointly provides data storage and business access to the outside world. Compared with traditional storage devices, cloud storage is not just a piece of hardware, but a complex system composed of network devices, storage devices, servers, application software, public access interfaces, access networks, and client programs. Each part takes the storage device as the core, and provides data storage and business access services to the outside world throu...

Problems solved by technology

[0004] In the existing technology, the data requested by the user is stored from the cloud to the local cache at the client end, and then the data is read from the local cache. The above process of obtaining data is slow and cumbersome

If the user does not pass the cache, the user directly downloads the requested data from the cloud. Due to the limited network speed, it is relatively slow for the user to directly access the cloud storage to obtain data.
