Abstract

The invention relates to a tape library based data protection system and method. The data protection system comprises a data backup server and a tape library, wherein the data backup server comprises a backup data storage module, a data archiving module and a position database, the backup data storage module is used for storing data backed up on a production server and a corresponding time point data set; the data archiving module is used for establishing a data archiving task, archiving data stored in the backup data storage module to the tape library according to the data archiving task by taking the time point data set as a unit and also recording the position of each data object in the tape library; the position database is used for storing positions of the data objects in the tape library. Compared with the prior art, the tape library based data protection system and method can effectively protect data, can reduce the cost by utilizing advantages of a tape and also facilitate management of data in the tape.

Description

technical field [0001] The invention relates to the technical fields of data archiving and disaster recovery, in particular to a tape library-based data protection system and method. Background technique [0002] Tape library is a very important part of the current data storage system. The tape library not only has a large storage capacity, but also has great advantages over tape drives and hard disks in terms of cost, energy consumption, reliability and mobility. [0003] With the development of information technology, data is becoming more and more important for every industry. Therefore, many enterprises and governments use various data protection products to back up their data. Most of the existing backup products save the backup data to the disk. As data volumes increase, costs skyrocket. In contrast, most data on disk is rarely used. Therefore, archiving infrequently used data to inexpensive tape became a natural choice. [0004] The traditional tape backup metho...
