毕业设计 题 目 学 院 专 业 班 级 学 生 学 号 指导教师 二〇一 年 六 月 ABSTRACT With the advent of the information age，use data explosion to describe our current information society has none exaggerative.At least 1.44MB floppy disk from to TB remember disk array,storage medium is growing with thousands of times. The information age to give each of us bring convenience self-evident. For example,convenience shopping online 、Safety and convenient online bank Omniscient baidu Google,And on the Internet for innumerable we learnt huge compendium of knowledge. You imagine someday Internet data lost what will happen,stocks、bonds 、bank …… Almost all of the industry will be paralyzed, our life will limping. Information as the cornerstone of the current social development,as each provide service enterprise has the obligation to ensure that their responsibility and the data provide information security, to ensure that we are living in orbit. How to guarantee the safety of enterprise data ? Data backup tolerant cannot small gaze. General enterprise data in database management. Currently, the most favored by the enterprise of Oracle database,So my graduation design is mainly to the current mainstream server operating system (Windows server 2003 / in 2008, Linux, Unix) is shown to backup software with the Oracle database backup and tolerant design，And on the HP small shown backup software DB2 database using the backup and tolerant design. Design the function will realize in the lab building up. Lab 2 sets of environment are mainly DELL servers (Windows server 2003), a VTL150G2 with a virtual tape library, a ISUM450G3 disk arrays, with a small machine (2 sets of IBM, Unix). Through the enterprise data storage environmental simulation and the completion of enterprise database backup and tolerant design is realized.Finish to the analog enterprise data storage environment after the backup and tolerant, will ensure t
