Agree with the last two entries.
 
In my opinion the wake up interval has nothing to do with it. It sounds
like the server is being hammered, new media server required.

    I would split the backup load by adding another media server.

Hi,

Our netbackup master-media server a SF6900 with 4 dual core CPU's and 16
Gb of memory is 100% utilized all the times. The only time it gets some
respite is during the afternoon, when users do not want to load their
system with backup processes.

Even with 20 Active backups our server indicates a minimum of 95 % util.
I checked ps -ef and found numerous bptm and bpsched processes.

How can we reduce the bptm processes??? I spoke to an ex-colleague and
he opined that we change the scheduler invocation to 20 mins from the
default 10 mins in the global attributes. Since we have around 1000
policies and hence the scheduler might not able to complete its first
round and meantime nbu would invoke another one. This overlapping he
said shd be reduced.

Any suggestions to reduce CPU load on netbackup server, especially as to
what might be invoking these bptm processes??????
