Matching tree-based terminal information backup method and backup device

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...

AI Technical Summary

Problems solved by technology

[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 embedded devices 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 progress of mobile collection

[0008] Traditional judicial forensics always uses the backup method for iPhone smartphones. This method also has the shortcomings of the above-mentioned general backup method, which consumes a lot of time, and the backup files obtained are often huge and occupy a large amount of storage space. A small number of files, you also need to back up the entire phone, and then search for the corresponding files, which is extremely inefficient

[0009] Therefore, the traditional backup method can no longer meet the requirements of efficiently and accurately collecting and obtaining specific information with high timeliness for smart mobile terminals
