Pls call a Veritas support - You can't fix this yourself.
There is possibility to build a new master server, and do media import from the media server. But media import will take days or even weeks and the complexity is high. Also the import is highly dependant on what media backups are stored on (disk,tape, MSDP)
You cannot add backup files manually to a new master server. The files alone doesn't do it. The Netbackup catalogue need to know what backup exists and where they are located.
A highly trained Netbackup consultant can help you.
It is impossible to assist you all the way thru forum posts.
