Good catch I was pretty sure this was mentioned into the documentation,
https://docs.bareos.org/TasksAndConcepts/BareosConsole.html#bcommandsetdebugYou can only guess it with the trace parameter which become active with =1 and inactive with =0
Same for setdebug level=0 all will deactivate all debug on all daemon and also trace.
if you're playing with trace file, watch out the disk space they can easily improper sized /var/lib/bareos.
