Problems solved by technology

The existing cloud storage mode is mainly reflected in the "cloud disk", which has the following problems: (1) Users put all files directly into cloud storage, and the number of cloud storage files increases exponentially due to the huge amount of mobile terminal data. As time goes by, the performance of the cloud storage system is reduced; (2) users can only read in units of files, and when the user only changes a small amount of data in the file, the entire file needs to be re-uploaded to the cloud, Reduced storage efficiency

Embodiment Construction

[0041] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] A mobile terminal-oriented cloud storage implementation method, as shown in Figure 1, uses a loop device to virtualize a common file into a block device (similar to a hard disk), and uses virtual block device technology to store all files in a mobile terminal into a virtual block device container. The loop device is a virtual device interface in the file system of the mobile terminal, and is used to shield users from direct access to physical files. The mobile terminal loads the virtual block device and treats it as a local hard disk. When reading a file, it can read some data blocks from the cloud storage system; when changing a file, first write the changed data into the memory of the mobile terminal and save it. Mark as dirty data blocks, and then only transfer dirty data blocks back to the cloud storage system.

Abstract

The invention relates to a method for achieving cloud storage for a mobile terminal. The method for achieving cloud storage for the mobile terminal is mainly characterized by comprising the following steps that step 1, a file is established on a cloud storage system and the cloud storage system is connected with a loop device; step 2, the mobile terminal has access to the cloud storage system in a block device accessing mode or a file accessing mode. The method is reasonable in design and the common file is virtualized to be a block device for use through the loop device. By the adoption of the virtual block device technology, all files of one mobile terminal are contained in one virtual block device container, so that exponential order incensement of the number of the files is avoided, isolation of the files between mobile terminals is achieved, and the performance of the cloud storage system is improved; meanwhile, block-level reading and updating are provided, the user network flow is reduced, and the user access efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mobile terminal storage, in particular to a mobile terminal-oriented cloud storage implementation method. Background technique [0002] With the widespread promotion of 3G and WIFI services, the mobile Internet has begun to penetrate into various fields of society and life, and terminal applications have also shown explosive growth. Mobile terminals have gradually become a new application platform. With the development of the mobile Internet, users have higher and higher requirements for terminal storage space. However, the bottleneck of limited mobile terminal resources has always restricted the development of terminal storage space. Taking Apple's iPad product as an example, the built-in storage space currently provided Only up to 128GB. [0003] With the emergence of cloud storage technology, it provides a feasible solution to solve the bottleneck of terminal storage. Cloud storage refers to using th...
