BRILLIANT Marianne and Andy
I really appreciate ur great support, i checked the catalog and yes i found that offline backup is configured there.
i choosed that offline catalog start when manually intiated and it successed.
when i try to configure no media to be used then i got that error msg:
i guess that happened coz the tape (6560L4) is not available in the robot and so cannot be deassigned.
the good news that i have that tape stored offsite and i will insert it by tomorow.
one more two things:
1. how can i browse the netbackup guides u linked to me, do they need an authorized account?
2. it will be great if i can got a guide that explain how to configure Media and Master Netbackup Servers :)
many thanks.
