Ah... So its not a true system backup then... So I suppose the peak you get is when it is actually zipping when is to be sent...
Maybe all you have to do is to monitor the phenomenon, if it is that, then write a script to point out the process from your alert

that is exactly what i'm doing vbe Smilie a .sh to make the process go down in priority a bit not too much and relase some load on the task ( lower the cpu load ) and prevent the alert on my email from the CPU Health monitor Smilie

Will this work for you?
Code:
if [ $( ps -ef | grep -v grep | grep -c backup ) -eq 1 ]
then
      UNIX95= ps -ef -o pid,pcpu,args | grep backup | grep -v grep | read _PID _CPU _ARGS
      if [ ${_CPU} -gt 95 ]
      then
            # renice priority ${_PID}
      fi
fi

hmmm why, not a while loop to keep track if the process is on or not.

well bipinajith i have your script on my crontab.hourly Smilie small question why you have the the read parameter on the UNIXPROC ... variable and why you dont refer to the unixproc to find the values on the if -gt 95 ?

This one does work on my linux/bash system; not sure it will on yours as you don't mention details:
Code:
while read PID CPU REST < <(ps -eo pid,pcpu,args|grep [b]ackup)
      do echo $CPU
         sleep 2
      done

This one will print the backup process' CPU percentage every other second. Replace echo with what you need, e.g. if [ "$CPU" -ge 95 ]. If the process does not exist or disappear, so does the loop. Make sure you only grep the one backup process of interest, eventually you have to narrow down the grep pattern.

Code:
while read PID CPU REST < <(ps -eo pid,pcpu,args|grep [b]ackup)
      do 
         if [ "$CPU" -ge 95 ]
         then
           renice -1 $PID
         fi   
         sleep 2
      done
