Research On Data Backup Of IP-Storage Network

The development of computer network has leaded a revolutionary change in storage technology.Mainly manifested in the rapid expansion of the capacity of data storage;Storage structure networking,storage systems have been developed into an independent system.Network storage has become the third wave of IT field.IP storage technology as a new network storage technology has been rapidly developed, more and more enterprises choose the IP storage as the storage solution.On the other hand,with the rapid development of information technology,computer systems have become the infrastructure of enterprises.The data,which is the lifeline of the corporations,has become the key resources to its survival,the value of data is much more than the equipment.However,the uncertainty,such as virus,Trojan,software failure,and man-made mistake threatening the security of the data,data security issues become increasingly prominent.All levels of users of computer information system have also been actively concerned about the safety of their own system;to pay more attention to the security of data storage,backup systems which protect their data security has become a crucial system.Data backup is a data security strategy and effective measures to protection of data;it has become a high-profile research in the field of information security.This article combined with today's enterprise storage and backup needs,designs a backup storage system based on tripartite structure,using B/S structure and Web browser to control the operation of the entire system.Data can be backup and recovery in any place.System meets the needs of business users to design their own backup solution.From the backup servers,storage servers,backup agents interact to achieve the tripartite agreement.Physically,the subsystem runs independently. Logically the backup server directing the whole system,backup agents and backup storage server receive commands which are sent from the server to run the task.User use web browser to control the backup system.This article focuses on the IP-based network data storage backup systems involved in key technologies,the thesis main completed the following work: (1) Study the current prevalence of network storage and backup technology, focused on IP-based iSCSI storage network.(2) Propose a storage backup system based on tripartite structure,which can be extended to the realization of IP SAN serverless backup.Depth studies the key technologies in the network backup system.(3) Of the system architecture,the functions of the various sub-systems were discussed in detail,and each subsystem has been designed and realized.(4) To test the main functions of backup systems and performance,test results show that the system can work normally,design and implementation is feasible.
