Embodiment Construction

[0035] The embodiments of the present application provide a data backup and restoration method and electronic equipment, which solve the technical problem of low backup rate existing in the prior art.

[0036] The technical solution of an embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:

[0037] Obtain a backup instruction; based on the backup instruction, send a data transmission request to the second electronic device; after receiving the data transmission permission response sent by the second electronic device, determine the difference between the first data and the second data based on the first data and the second data. Difference data with different data; the difference data is stored in the second electronic device, so the information redundancy stored in the storage unit can be reduced, storage resources can be saved, the operation is simple, the time consumption is short, and the backup rate is fast.

Abstract

The invention discloses a data backup and recovery method applied to first electronic equipment and electronic equipment. The first electronic equipment is connected with second electronic equipment and comprises first data. The second electronic equipment comprises second data. The first data and the second data have repeated data. The method includes: acquiring a backup instruction, and transmitting a data transmission request to the second electronic equipment on the basis of the backup instruction; determining the data, which is different from the second data, in the first data on the basis of the first data and the second data after the response which allows data transmission and is transmitted by the second electronic equipment is received, and storing the different data to the second electronic equipment. The method is simple to operate, fast in transmission and low in storage space requirement, and data backup can be achieved without synchronization tools.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data backup and recovery method and electronic equipment. Background technique [0002] An operating system is usually installed in an electronic device, for example, a computer is installed with a Linux, Unix, and widows operating system, and a smart phone is installed with an Android, Symbian, and IOS. In order to make the functions of electronic equipment more perfect, more powerful and secure, suppliers will launch an updated version of the operating system. Compared with the original operating system, the updated version of the operating system adds some operating system data, and the operation of the updated version During the system update process, the user's basic setting data will be cleared. [0003] In the prior art, the method for updating the operating system specifically includes: backing up the original data of the electronic device, and backing up the dat...
