Virtual Tape Library Software Technology In The Backup System

Today the data was the life for information system.The data backup was one of the best ways for data protection and it was easy to deploy. The National Stadium Committee had taken on construct the bird' s nest that was the Olympic stadium for opening and partial Olympic game and closing ceremony,so datacenter had to face the exponential data growth since 2001.There were storing very important unique data for reference and research for the construction industry.There are going to build high performance data backup system for keep data safety and realize continuous data protection.The backup appliance is the key for whole system.The brand-new device shall be focused on faster backup and reduce restore window while do disaster recovery.The appliance shall be higher security and better reliability and perfect scalable ability at performance and storage capacity.The physical tape library did not meet current requirement.The disk backup solution was real hard to practice and management that disk backup did not meet with automatic backup policy of backup software.The backup system should choose advanced technology to face the challenge according to the technical Olympics tenet.The virtual tape library software as next-generation technology has been fully recognized by overseas that is the key to turn on total solution for data backup.The virtual tape library software technology use application session to simulate feature of physical tape library and use disk as cartridge to replace the tape.There are no mechanical components in virtual tape library so the appliance present higher performance and larger capacity and better security and better reliability and perfect scalable ability. At first analyzed current situations and disadvantages of backup system devices that included disadvantages of physical tape library devices and limit of disk backup solution these gave full reason to choose innovative software technology.According to these conditions to analyze the data security level of the National Stadium Datacenter of the Committee followed according to the data lifecycle management of the datacenter to analyze the detailed requirements of brand-new backup system.And then analyzed the development of virtual tape library software technology and researched the kernel and the infrastructure and the functions and operating processing of its.There were three majors that included backup system programming and virtual software deployment and management to describe the implementation of the software technology implementation for understood the reason of choice.There was very important viewpoint to be innovated at technical theory and practicing method which viewpoint was the Large-scale Integrated High-speed Virtual Tape Library Architecture(LIH-VTLA).The section lucubrate the configuration and the effect of the application technology.And then based general functions of virtual tape library software technology to lucubrate regarding how to make more innovative functions through integrate with other software technology for served the whole information system.At the end of dissertation around the virtual tape library software to sum up the advantage of human society and possible impact and the future plus evaluated commercial value.
