Sorry - I don't have such a script to do exactly what you want. But below is a script that monitor backup that run too long. I hope you can gain inspiration from it:
#!/usr/bin/ksh
ALARM_TRESHOLD=84000
RUNTIME=0
/usr/openv/netbackup/bin/admincmd/bpdbjobs -most_columns | awk -F "," ' $3 ~ /^1$/ { print } ' | awk -F "," ' $2 ~ /^0$/ { print } ' | awk -F "," '{ print $1, $3, $6, $7, $10 }' | while read PID STATE SCHEDULE CLIENT RUNTIME
do
if [ RUNTIME -gt ALARM_TRESHOLD ]
then
echo "Job ${PID} ${CLIENT} ${SCHEDULE} runtime is ${RUNTIME}. It's exceeded runtime treshold of ${ALARM_TRESHOLD} "
fi
done
