Hi,
I can tell by your reference to "bp.conf" that you are talking about UNIX. However, I am not sure about the term "restore trace". Do you mean a logfile? That is created with the option bprestore -L progress_log_name. Or by enabling the log in the GUI. I don't know which GUI you use xbp, java, admin console? But they all have a way to enable a progress log.
If you need additional information then you can create the debug log directories under /usr/openv/netbackup/logs/bp...
Always be careful to have plenty of disk space if you turn on verbose in the bp.conf or perhaps create a link to another file system for /usr/openv/netbackup/logs
