Abstract

The invention provides VTL (Virtual Tape Library) equipment and a data recovery method. The VTL equipment comprises a VTL interface module for receiving data backup commands and backup data from a backup server and sending to an I/O (Input/output) management module, an NAS (Network-attached Storage) for receiving data recovery commands from user equipment and sending to a file driver module, a VTL configuration module for allowing storage media to be a virtual tape and responding to the data backup commands and generating virtual tape configuration information corresponding to backup data, the file driver module for obtaining virtual tape configuration information corresponding to the backup information to be recovered from a VTL configuration module, and the I/O management module for reading the backup data into a disk according to the virtual tape configuration information when the data backup is performed, wherein the recovery data are read from the disk according to the virtual tape configuration information, and return to the user equipment through the NAS interface module.

Description

Technical field [0001] The invention relates to data processing technology, in particular to a virtual tape library device and a data recovery method, and belongs to the field of wireless communication technology. Background technique [0002] With the popularization of informatization and the explosive growth of structured and unstructured data, more and more companies and individuals are beginning to realize the importance of data protection and increase investment and construction. A data backup system composed of data backup software and Virtual Tape Liberary (VTL) equipment has become a popular solution. [0003] figure 1 It is a data flow diagram for data backup based on data backup software and VTL equipment in the prior art. Such as figure 1 As shown, the data backup software on the backup server packages the data on the client A and the client B according to the backup strategy, and then uses the virtual tape as the backup medium to back up the packaged data to the VTL de...
