Abstract

The invention discloses a data backup device. The data backup device includes: a detection module for detecting operation instructions corresponding to the data of a full data set in a mobile terminal; an acquisition module for obtaining pre-backup data in the mobile terminal Set and full data set; change module, used to change the measurement value of the full data set and the index of the pre-backup data set according to the operation instruction, wherein the measurement value represents the change status of the data in the full data set, and the index is used to identify the full data set the data in; a backup module, configured to back up the data corresponding to the index in the pre-backup data set if the measurement value is greater than a preset threshold. The invention also discloses a data backup method. The invention realizes the fine-grained incremental backup method based on the measurement value, controls the amount of data backed up and the backup frequency according to the measurement value, adopts the incremental backup method to avoid redundant storage of data, reduces the cost of data backup, and improves the efficiency of data backup .

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data backup device and method. Background technique [0002] With the rapid development of mobile communications, the software level of mobile terminals has been continuously improved, which not only provides users with superior user experience, but also greatly improves people's work efficiency and quality of life. During the use of the mobile terminal, a large amount of important data information of the user is stored on the mobile terminal, such as address book, schedule, short message and so on. Once the mobile terminal is lost, the user deletes it by mistake, or other operations that may cause the data to be unusable, it will bring huge troubles to the user. Therefore, the data in the mobile terminal needs to be backed up. [0003] In the process of backing up the data of the mobile terminal, the security, reliability and availability of the data must be guarante...
