There are no logs. The data is kept in a database under netbackup/db/jobs.
It is unreadable with normal desktop apps.
You can customise the GUI view to display all the columns you want and then simply save it to a text file
, which can be imported into Excel.
You can also try bpdbjob (as is) or with -most_columns, but you cannot choose which columns.
I find the Activity Monitor export feature the easiest.
