What services?

Hello all,

I have Netbackup 7.6 running on W2008. I just set up the KEEP_JOBS_SUCCESSFUL_HOURS and KEEP_JOBS_HOURS for two weeks, so far so good, but now I need to restart the services and I just realize that Netbackup has 34 services.... and wondering if everything I do I'll need to restart 34 services....

So my question is: Do I need to restart all the 34 services for setting the jobs retention? Or is there any kind of rule I can follow to know which service is responsible for what?

Thank you very much in advance for everybody able to assist.
