Example Embodiment

[0067] Example one

[0068] Please refer to figure 2 with image 3 This embodiment provides a method for backing up terminal information based on a matching tree, which is suitable for performing specific information backup operations on all terminals that need to perform information backup. It is especially suitable for the ios system, which has high system security restrictions and cannot be backed up only for specific information.

[0069] This embodiment can realize accurate and efficient backup of specific information, which not only shortens the time required for backup, but also reduces the space occupation of redundant files without any improvement to the backup terminal, and significantly improves the efficiency of backup. It has a wide range of application scenarios to better meet actual needs, especially to greatly improve the work efficiency of relevant judicial forensics staff, save valuable time and expenditure, and powerfully support the rapid and effective developm...

Example Embodiment

[0106] Example two

[0107] This embodiment corresponds to the first embodiment and provides a backup device based on a matching tree, including a storage unit storing a computer program, and the computer program can implement the All steps included in the method of backing up terminal information of the matching tree. For specific steps, please refer to the description of the first embodiment, which will not be repeated here.

Example Embodiment

[0108] Example three

[0109] This embodiment corresponds to the first embodiment and provides a terminal information backup system based on a matching tree. Please refer to Figure 4 , Specifically including backup devices and terminals to be backed up. The terminals to be backed up can be any terminal devices that require data backup, such as mobile phones, tablets, etc., especially those equipped with ios systems that have high security restrictions and cannot achieve only A smart terminal that backs up specific data.

[0110] In this embodiment, the description is made by taking the terminal to be backed up being an iPhone as an example, but it is not limited to this.

[0111] 1. Terminal to be backed up

[0112] The iPhone to be backed up has an inherent synchronization service component. The synchronization service component serves as a backup service component to provide data synchronization services. The synchronization service component belongs to the inherent service of the ...

Abstract

The invention provides a matching tree-based terminal information backup method and a backup device. The method comprises the steps of presetting a configuration file, wherein the configuration file comprises a start identifier, packets corresponding to to-be-backed up applications and matching entries which are corresponding to the packets and composed of matching items corresponding to to-be-backed up file names or directory names; constructing a matching tree which takes the start identifier as a root node and takes the packets and the matching items in the matching entries corresponding tothe packets, which are sequentially distributed step by step, as tree nodes according to the configuration file; matching file names sent by a to-be-backed up terminal with the matching tree; and ifthe matching is successful, storing the file content corresponding to the file names. The method provided by the invention has the advantages of accurately collecting the specific backup information in batches, reducing the IO (Input/Output) writing, reducing the backup time, improving the backup efficiency, reducing the occupied space of redundant files, reducing the energy loss of equipment andterminals and the like.

Description

technical field [0001] The invention relates to the field of information backup, in particular to a matching tree-based terminal information backup method and backup equipment. Background technique [0002] At present, the information backup method for terminals (such as mobile phones, tablets, etc.) is mainly performed by connecting external devices to the terminal. The existing terminal information backup methods mainly have the following deficiencies: [0003] 1. A large number of files of different sizes frequently write to the disk, and there is an IO bottleneck; [0004] 2. The original backup mechanism has the problem of long backup time and slow speed; [0005] 3. A large number of redundant files are stored on the disk, wasting limited storage space; [0006] 4. The battery loss of the embedded device increases, and the device is connected to the terminal for a long time, which increases the power consumption of the device, which is not conducive to the continuous...
