1.在管理控制台（NetBackup Administrator Console）
Host properties >Master Servers > Servers >additional Servers and Media Servers 这两个选项中添加Media Server的主机名完成后重启NBU服务
2.修改EMMServer
nbemmcmd -addhost -machinename differ.com -machinetype media -masterserver nbserver.com -operatingsystem linux -netbackupversion 7.5
differ.com---------Media Sever Name
nbserver.com-------Master Server Name
linux--------------Media Server的OS
7.5----------------添加版本时，只前两位就行了，例如其他的：6.5等
3.修改Media Server的bp.conf
修改bp.conf的第一个SERVER = nbserver.com（Master Server），重启NBU服务
4.修改Client的Server
Host properties > Clients > Servers >additional Servers (添加Media Server的主机名)
5.相关一些报错的解决
