Restore to a different location

Had you seen the video link I post ?
It explains what to do to restore a file to an alternate server. 
It is windows BAR GUI but Java BAR GUI has the same functionality.  Open one of them from the master server and do the restore.

And this is the BAR manual

EDIT: I understand that the video is not easy to follow as it does not have audio.
Use master's server Java. Go to BAR (backup archive and restore and select the upper right icon with the hand

Do not change the master server, select the source, destination client and policy type.

be sure that all systems are correct under each headline

select the files are press "restore"

now select the path you want the restore must go ( original path or deferent path)

press start restore

My suggestions are:
Do not select the "override existing files". this will help you in case of error.
Do the netbackup Administration training
