Embodiment Construction

[0049] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be used mixedly.

[0051]Mobile terminals may be implemented in various forms. For example, terminals described in the present invention may include devices such as mobile phones, smart phones, notebook computers, digital broadcast receivers, PDAs (Personal Digital Assistants), PADs (Tablet Computers), PMPs (Portable Multimedia Players), navigation devices, etc. mobile terminals and fixed terminals such as digital TVs, desktop co...

Abstract

The invention discloses a data backup device and method. The data backup device comprises a detection module for detecting an operational order corresponding to data in a full data set of a mobile terminal; an acquisition module for acquiring a pre-backup data set and the full data set in the mobile terminal; a changing module for changing a measure value in the full data set and an index of the pre-backup data set based on the operational order, wherein the measure value indicates the change status of the data in the full data set, and the index is used for identifying the data in the full data set; a backup module used for backing up the data corresponding to the index in the pre-backup set when the measure value is greater than a preset threshold. The invention further discloses the data backup method. The fine granularity increment backup method based on the measure value is achieved. The backup data size and backup frequency are controlled according to the measure value, the data redundancy storage is avoided by adopting the increment backup method, the data backup cost is lowered, and the data backup efficiency is increased.

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...
