You can try parent_end_notify. - only runs on the master (easier to maintain)

# This script:

#       receives 5 parameters:

#         CLIENT           - the client hostname

#         POLICY           - the policy label

#         SCHEDULE         - the schedule label

#         SCHEDULE_TYPE    - the type of schedule:  FULL INCR UBAK UARC

#         STATUS           - the backup status for this job

#         STREAM           - the backup stream number for this job always -1

#       must be executable by the root user

#       should exit with 0 upon successful completion

You just have to put in If statements for each think you want to monitor

My example

Runs when the Parent of the Hot Catalog backup finishes

if [ $2 = "Hot_Catalog_Backup" ]

 then

 OUTF=/usr/openv/netbackup/bin/PARENT_END_CALLED.Hot_Catalog_Backup

  if [ -s $OUTF ]

   then

        /bin/rm -rf $OUTF

  fi

  if [ ! -f $OUTF ]

   then

        touch $OUTF

  fi

 echo ${dateStr} "-----------------------------" >> $OUTF

 echo ${dateStr} "       CLIENT:  $1" >> $OUTF

 echo ${dateStr} "       POLICY:  $2" >> $OUTF

 echo ${dateStr} "     SCHEDULE:  $3" >> $OUTF

 echo ${dateStr} "SCHEDULE TYPE:  $4" >> $OUTF

 echo ${dateStr} "       STATUS:  $5" >> $OUTF

 echo ${dateStr} "       STREAM:  $6" >> $OUTF

 echo ${dateStr} "-----------------------------" >> $OUTF

 /usr/sbin/rdist -f /usr/sysadmin/scripts/Data/Rdist_Dist_Netbackup_PROD >> $OUTF

 cat $OUTF | mail -s "Netbackup parent end notify for Catalog" someonewhocares AT mycompany DOT com
