Design and implementation of remote data backup and recovery system based on Linux

Abstract

In this paper,a Remote Data Backup and Recovery System(RDBRS) was presented and implemented to improve the efficiency of data disaster recovery.Through improving the frame of Rsync,the system used Inotify and snapshot to locate files that have been changed and to get file increments,and used Rsync to transfer data remotely.In this way,the system resource consumption and the amount of network traffic were greatly reduced,and data transmission speed increased about 10 MBps compared to Rsync in gigabit network environment.The experimental results show that the system has high practical value to small and medium enterprises without enough fund.
