Design And Implementation Case Of Digital Information Backup And Storage System

With the growing popularity of digital processing case information, computergraphics, digital camera, paperless office began to enter the public security work. Alarge amount of data and documents the resulting all need to use computer storage. Onthe one hand, along with the time development, case information is increasing, datastorage and the rapid growth; on the other hand, due to the need for long-termarchiving of the original information of the case, the data security of the increasinglyhigh demand. How to backup storage case information, avoid data disaster is one ofthe technical problems urgently need to be solved at present in the public securitywork.The system uses the C/S structure in the system structure, DELPHI with SQLServer2005as a platform for system design and implementation. This paper expoundsthe development needs of the system and practical significance, advantages anddisadvantages of the case of digital information backup storage method of comparisonamong the existing planning documents, storage and backup system based oncomputer network is a new. According to the existing network condition, the hardwarefacilities in the actual work was described, the server and disk array erection manner.Through the analysis to the system needs analysis, structure analysis and feasibility,carries on the analysis to the structure of the system, and is divided into variousmodules, mainly consists of setting module, network transmission module, timingbackup module, file real-time monitoring module, manual backup module, archivingmodule and restore module for the system and the flow chart. The tables in thedatabase are designed, then introduces the realization of the principle of system andfunction of each module, mainly on the design and implement file redundancy,backup file version. Analysis and Study on the difficulties in the development process,and through the image system structure diagram, use case diagram, sequence diagram,function block diagram, UML and other means to express. The system.The system is relatively simple to operate, with stable and reliable performance andfriendly user interface, to complete the basic work the case of digital informationbackup storage. Through the automatic, manual two kinds of case data archive backupand automatic redundancy cleaning, so as to improve the security of data, reduce thedata storage pressure, make the case file management more scientific, automation. After preliminary testing, the system can run well and realize backup, reductiondesign functions, each function module has reached the design target at the start of.But in the aspects of resources, improve the efficiency can be improved, the systemfunction in network security can also strengthen and increase assistance to inspectorssorting and statistical functions of case data, so that the practicability of the systemcan be stronger.
