We have around 3,000 policies and it takes about 40 minutes for BPSCHED to get 
through them.

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??????
