Data backup method and data recovery method

Abstract

The embodiment of the invention relates to the technical field of data processing, and particularly discloses a data backup method and a data recovery method. According to the embodiment of the invention, before a user needs to replace the equipment, the backup data of a first terminal is divided into the necessary data and the selected data, and the necessary data and the selected data are respectively uploaded to a first backup library and a second backup library; and and when the backup data of the first terminal needs to be restored through a second terminal, targeted data restoration transmission is performed on the data in the first backup library and the second backup library according to the data restoration selection of the user, and the data in the first backup library and the second backup library is cleared after data restoration is completed. Therefore, data backup can be carried out at a time, data loss and data chaos caused by long-time-span data backup are avoided, mismatching between the first terminal and the second terminal can be avoided, the data needing to be backed up are completely restored to the second terminal according to selection of the user, and convenience and rapidness are achieved.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a data backup method and a data restoration method. Background technique [0002] Data is a representation of facts, concepts, or instructions that can be processed by human or automated means. Data becomes information when it is interpreted and given meaning. Data processing is the collection, storage, retrieval, processing, transformation and transmission of data. The basic purpose of data processing is to extract and deduce valuable and meaningful data for some specific people from a large amount of data that may be messy and difficult to understand. Data processing is the basic link of system engineering and automatic control. Data processing runs through all fields of social production and social life. The development of data processing technology and the breadth and depth of its application have greatly affected the progress of human society. [000...

Problems solved by technology

The existing data backup and data restoration usually adopt the following two methods: one is to gradually back up and store the data of the device along with the use of the device, and restore the historically stored data at one time when replacing the new device. On the new device, this method of data backup and restoration, because the data backup takes a long time to upload, the stored data is messy, the backup data cannot be classified according to the importance, and the data is easy to lose; When replacing, establish a local network between the old and new devices, and then transfer the data of the old device to the new device through the local network to complete data backup and restoration. This method often results in a large amount of data being lost due to the mismatch between the old and new devices. Transfer directly to new device
