A method and a device for realizing cloud storage

Abstract

The disclosure relates to a method and a device for realizing cloud storage. The method comprises: receiving cloud storage strategies that are set by a user according to data synchronization requirement, wherein, the cloud storage strategies comprise mapping of a specified attribute file; monitoring operation from the user on a file of a client end in real time; in the case that the user executes, at the local client end, operation of creation, modification, or deletion on the file meeting the cloud storage strategies, executing corresponding operation on a file in a cloud storage server; and in the case that the user executes, at the local client end, the operation of deletion on the file meeting the cloud storage strategies, determining whether a strategy corresponding to the operation of deletion is removed from the cloud storage strategies according to the data synchronization requirement, and updating the cloud storage strategies in the case that the strategy corresponding to the operation of deletion is removed from the cloud storage strategies. The method and the device for realizing cloud storage can synchronize the specified files at different directories onto the cloud storage server without constructing the local virtual disks.

Description

technical field [0001] The present disclosure relates to the field of cloud computing, and in particular, to a method and device for implementing cloud storage. Background technique [0002] There are currently two schemes for building local virtual disks in cloud storage: (1) virtual disk scheme, that is, to create a virtual disk file locally, manually put the file to be synchronized into the virtual disk, and then synchronize it to the cloud storage; (2) mapping Directory scheme, that is, specify a directory locally, and synchronize the files in the directory to the cloud storage server. [0003] Compared with the virtual disk scheme, the security of the scheme based on directory mapping is relatively low; compared with the scheme of mapped directory, the scheme based on virtual disk needs a special virtual disk file, and there is a certain waste of resources. [0004] In addition, both of the above two solutions have the problem of insufficient flexibility. For example, ...

Problems solved by technology

[0003] Compared with the virtual disk scheme, the security of the scheme based on directory mapping is relatively low; compared with the scheme of mapped directory, the scheme based on virtual disk needs a special virtual disk file, and there is a certain waste of resources

[0004] In addition, both of the above two solutions have the problem of insufficient flexibility. For example, neither of these two solutions support mapping a specific type of file as a component of a virtual disk, which makes it inconvenient for customers to synchronize it to the cloud storage server.
