what will be the ideal process-max number to use ?

 Once I update the process-max param in pgbackrest.conf ,  do I need to
stop and  start the pgback rest ?

Or just editing the pgbackrest.conf  on the fly will reflect the increased
process-max  numbers advantage ?

Is there a limit for proces max. setting ?
