Research And Implementation Of Remote File Backup System

In the meteorological monitoring system,nodes collect all kinds of meteorological information and temporarily save them to the local disk.Due to the long-term observation and research of meteorological information,temporary preservation cannot guarantee the security of information.Therefore,it is valuable to back up the collected weather information and save it for a long time.The paper researches and implements a set of remote file backup system for the long-term storage of meteorological information at an airport in China.The paper first studies the existing backup technology and backup system status,analyzes the actual requirements for long-term storage of the airport meteorological information,and then designs the overall framework and business process of the remote file backup system suitable for long-term storage of airport meteorological information.The various modules of the system are implemented.The main work of the thesis includes:(1)The status quo and development of data backup at home and abroad were investigated.The status of file backup at an airport in China was investigated.The function and performance requirements of the system were thoroughly discussed.The detailed requirements analysis was performed on the actual demand.(2)Design a B/S architecture suitable for remote file backup systems,use MVC architecture for system layered design,use FTP protocol to control file network transmission,use an SSH framework for the overall framework,and use Oracle database for data storage and data exchange.(3)The system is based on the Windows platform,developed by Java language.It is divided into four modules: system management,data archiving,data auditing,and data reporting.Among them,the system management module completes the setting of important parameters of the system;the data archiving module completes functions such as automatic backup of remote files,manual backup,manual recovery,and log recording;the data verification module meets the requirements for the verification of meteorological data,including the import of meteorological data,Display,review and save;data report module is responsible for the classification display and report generation of meteorological information.(4)Test system functions and performance,and adjust and repair imperfect modules based on the test results so that the system meets the requirements for integrity,safety,and stability.At present,the remote file backup system designed by this paper has passed local testing and on-site commissioning,and it has officially launched on an airport in China.The practice has proved that the system meets the needs of remote file backup,meteorological data processing,and report generation at the airport,and has achieved the expected goal.
