Embodiment Construction

[0071] The present invention will be further described below through specific embodiments and accompanying drawings.

[0072] The present invention adopts the idea of ​​intelligent fusion of different cloud storage services, and based on this idea, provides perfect support and methods for the rationality, reliability and transparency of multi-cloud-based mobile terminal storage management.

[0073] This intelligent integration idea aims to think from the perspective of users' own needs, combine the respective advantages and characteristics of different cloud storage services, and virtualize a cloud storage service with high reliability and practicability.

[0074] The rationale for multi-cloud-based storage mainly includes user experience and cost. Among them, the main evaluation indicators of user experience are access speed, capacity, and whether the operation is convenient and simple. Specifically, a dynamic method of recording and updating cloud storage service indicators ...

Abstract

The invention discloses an intelligent mobile terminal data storage and backup method and system based on multi-cloud storage. The method comprises the steps that firstly, an intelligent mobile terminal selects a plurality of cloud disks to carry out the authorization authentication, and an authorized cloud disk set R is obtained; secondly, a multi-cloud storage scheme planner converts the attribute information of a file to be stored and backed up into a storage vector U, and a user requested cloud disk attribute weight vector W is calculated according to U; thirdly, the multi-cloud storage scheme planner searches the set R for a cloud disk subset R' with the residual space suitable for the file to be stored and backed up, for all cloud disks in R', a cloud disk weight vector Qw is generated according to the expectation value vector mu for attributes of the cloud disks of a user, the final weight of the cloud disks is calculated according to Qw and W, m cloud disks are selected from the set R' as a multi-cloud storage system, the reliability index P of the system is calculated, if P is larger than or equal to Fp, the file to be stored and backed up is stored into the candidate multi-cloud storage system, and Fp is the reliability index set by the user.

Description

technical field [0001] The invention belongs to the technical field of mobile Internet, and specifically relates to a multi-cloud storage service-oriented smart mobile device data storage and backup system and method, which can realize reliable data storage and backup of smart phones and other mobile terminal devices, and avoid the problem of "manufacturer lock-in" , where the selection, data transmission, management and other functions of multiple cloud storage services are transparent to mobile device users. Background technique [0002] With the help of feature-rich application software, smart mobile terminals have quickly penetrated into all aspects of people's lives, especially smart phones. With the rapid popularization of mobile smart terminals and the large-scale coverage of mobile networks, mobile applications continue to grow. Individuals download mobile applications and generate a large amount of information, including photos, documents, recordings, etc., and stor...
