Background
Currently, nbu (backup system) is mainly adopted as centralized backup software in the prior art, and tape library media are adopted to store backup data. According to the environment architecture of nbu, backups are divided into three layers, namely a main control server, a medium server and a client. The main control server is mainly responsible for backup strategy and backup task scheduling, the client is data to be backed up, the medium server is a main backup server, and the tape drive is configured on the medium server, so that the data can be written into the tape drive from the client to the backup medium server. Tape drives are typically distributed to backup media servers in logical tape library units, because nbu centralizes the SSO of the tape provided by the backup software, i.e., tape sharing functionality, meaning that a set of logical tape libraries (a set of tape drives with similar functionality) can be distributed to multiple media servers by a colleague. And the backup strategy can be backed up by using the logic tape library downloaded by the media server after being distributed to the media server.
