Linear expansion method and system for data backup based on public cloud storage account

Abstract

The invention discloses a data backup linear capacity expanding method and system based on a public cloud storage account. The method includes that a personal private cloud storage system account is bound to a public cloud storage account and a wifi-enabled storage device; the directory and file names of the public cloud storage account is subjected to traversal at the first time and storage; the personal private cloud storage system generates a plurality of task groups and waits for the wifi-enabled storage device to actively obtain; after the storage device is connected to internet, the storage device obtains tasks and automatically starts to download task data from the public cloud storage account and feeds the residual storage space back; if the residual memory of the storage device is lower than a preset value, the storage device is set in an inactive mode, and stops the synchronous operation until the storage device converts into the active state by deleting data or a new storage device is added. The content of the cloud storage accounts can be intelligently and automatically backed up to the local storage device, and the linear capacity expanding of the local storage device can be realized.

Description

technical field [0001] The invention relates to a linear expansion method and system based on data backup of public cloud storage accounts, and belongs to the technical field of data backup of public cloud storage accounts. Background technique [0002] Cloud storage is a new concept extended and developed from the concept of cloud computing. It refers to the integration of various types of storage devices in the network through functions such as cluster applications, grid technology or distributed file systems. A system in which application software works together to provide data storage and business access functions. In the cloud storage system (that is, public cloud storage accounts, such as Baidu Netdisk, 360 cloud disk, Jinshan Kuaipan, etc.), the amount of data that can be stored is large, so many users share files (such as photos, Documents, etc.), often send personal private files to the cloud storage system for storage. But at the same time, new problems are gradu...

AI Technical Summary

Problems solved by technology

But at the same time, new problems are gradually exposed: for example, if the cloud account is stolen, the user's personal privacy is likely to be leaked

In addition, if there is a file update in the cloud storage system, the user still needs to manually identify and download it to his personal mobile hard disk

The above-mentioned operation method is complex and cumbersome, requires manual operation, and cannot meet the requirements of people's intelligence

In addition, during the backup process, the following problems will also be encountered: for example, the mobile hard disk A used for backup is full, how to use the mobile hard disk B to continue downloading and how to avoid repeated downloads and updates are also problems that people urgently need to solve
