Real-time Network Backup System Based on Linux Kernel

LI Minyu(Shanghai Research Centre of ZTE Corporation,Shanghai 201203)  
This paper presents a real-time network backup system(RTNB) based on Linux kernel,and implements a prototype based on linux-2.4.19 kernel.The prototype system is working in the kernel,and it is transparent to user.At the entrance of the device driver layer,each block is encapsulated to be a three-domain element(data,block number,block size),and the element is transported to the remote backup server.RTNB system implements a partition-to-partition backup from local server to backup server,when the file systems of both sides are the same.The experimental results show that the time spending of storage of both synchronous backup and asynchronous backup are little longer than that of local storage when the bandwidth is 100 Mbps,and the efficiency is satisfying.
