A virtual cloud disk method and system

Abstract

The invention discloses a virtual cloud disk method, comprising: binding and virtualizing an application data folder in at least one cloud disk of a user into a virtual disk; the content corresponding to the virtual disk is the application data of all bound cloud disks The union of folder contents; obtaining the directory tree information of the application data folders of each bound cloud disk as the second directory tree of the corresponding cloud disk; taking the union of all the second directory trees bound to the cloud disk to create the first directory tree; set the location attribute for the node of the first directory tree; the location attribute identifies the corresponding relationship between the corresponding virtual disk file or folder and the bound cloud disk; redirect the access to the virtual disk to the corresponding cloud disk according to the first directory tree . The invention also discloses a virtual cloud disk system. A virtual cloud disk method and system of the present invention forms a virtual cloud disk by binding cloud disks and provides a unified interface, so that the application does not need to adapt to the interface of different cloud disks, and the user can also expand the space of the cloud disk horizontally, which is helpful for the application Cloud-based development.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a virtual cloud disk method and system. Background technique [0002] With the maturity of cloud technology, more and more applications hope to save user data (such as photos, notes, documents, etc.) to the cloud. There are also more and more manufacturers providing cloud disk (also known as network disk) services, such as Baidu Cloud Disk, Alibaba Cloud Disk, Huawei Cloud Disk, Amazon Cloud Disk, etc. [0003] The interfaces provided by the cloud disks of different manufacturers are generally different, and different users have different choices of cloud disk providers. In order to support as many users as possible, application developers need to support as many cloud disks as possible, and therefore need to develop based on the interface of each cloud disk, which poses a challenge to application manufacturers. [0004] On the other hand, users may use multiple c...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that different cloud disk interfaces in the prior art are different, and users often apply for multiple cloud disks, which causes inconvenience in application development and user use, and it is difficult for applications to make full use of multiple cloud disks owned by users storage space, the purpose is to provide a virtual cloud disk method and system to solve the above problems
