Embodiment 1

[0104] A method for reading and writing based on virtualization technology, said method comprising the following steps:

[0105] The driver module takes over the read and write operation instructions issued by the user to the specified directory of the terminal;

[0106] Process the read and write operation instructions according to the network connection status, and send them to the server or the local cache of the terminal;

[0107] Process the read and write operation instructions in the local cache of the server or terminal and send the processing result to the user.

[0108] The step of taking over the read and write operation instructions sent by the user to the specified directory of the terminal is through the virtual directory (that is, to virtualize multiple storage devices, and then (with the help of the virtual file system of the Linux kernel) mount these storage devices to the specified In the directory nodes, these directory nodes are turned into virtual directo...

Embodiment 2

[0129] A data backup method based on virtualization technology, said method comprising the following steps:

[0130] Take over the backup command issued by the user to the specified directory of the terminal;

[0131] Process the backup command according to the network connection status, and send it to the local cache of the server or terminal

[0132] live;

[0133] processing the backup instruction in the local cache of the server or terminal and sending the processing result to the user;

[0134] After receiving the backup instruction, the server creates a new blank image file as the new current image. Mark the original current image as the dependent image of the new current image, and send the operation success result to the terminal.

[0135] The steps of taking over the backup instructions issued by the user to the specified directory of the terminal: through the virtual directory (that is, to virtualize multiple storage devices, and then (with the help of the virtual...

Embodiment 3

[0164] A data restoration method based on virtualization technology, said method comprising the following steps: a user selects a saved image as a new current image through a terminal binary executable file, issues a restoration instruction,

[0165] Take over the restore command issued by the user to the specified directory of the terminal,

[0166] Process the restore command according to the state of the network connection, and send it to the server or the local cache of the terminal;

[0167] When connected to the Internet:

[0168] Try to read from the local cache of the terminal first, if there is no local cache, then read from the server;

[0169] When there is no network:

[0170] read from local cache;

[0171] Processing the read and write operation instructions in the local cache of the server or terminal, the process is as follows:

[0172] After receiving the restoration instruction, the server sets the image selected by the user as the current image,

[0173...

Abstract

The invention relates to a read-write method based on a virtualization technology. The read-write method includes the following steps that a read-write operational instruction sent to an appointed catalogue of a terminal by a user is taken over; the read-write operational instruction is processed according to a network connection state and then sent to a server or a local cache of the terminal; the read-write operational instruction is processed in the server or the local cache of the terminal, and a processed result is sent to the user. The read-write method and system based on the virtualization technology make the read-write operation not to be restrained by the storage medium capacity of the terminal, reduce space waste and improve user experience.

Description

technical field [0001] The invention relates to the field of data backup and restoration, software deployment, server storage and transparent computing technology. Background technique [0002] As computers, tablets, mobile phones and other electronic devices have entered every aspect of people's daily life, the security of user data has attracted more and more attention. Data security not only includes data not being stolen by outsiders, but also includes data not being lost due to misuse, equipment damage and other reasons. In order to avoid data loss due to various reasons, the data is usually backed up regularly and restored when necessary. [0003] The Android system is an operating system led and developed by Google and the Open Handset Alliance. It is an open source operating system based on Linux. It is mainly used in electronic devices such as smartphones, tablet devices, and smart TVs. The system architecture of the Android system, like its operating system, ad...
