If you think the rest of your NetBackup and network infrastructure are
already tuned for performance as far as is possible the only things you
can do when using the NBU Oracle standard agent are tune the number of
channels/streams and the block size in the RMAN script as mentioned. If
you are not a DBA you should push this task over to a collegue who is as
this is straight forward for someone who understands RMAN.
Also as mentioned you could also look at the options available with the
NBU advanced client which may improve performance, however they will also
probably make the configuration significantly more complex.....
thanks Andy.

Subject: Re: [Veritas-bu] backup speed
thanks a lot.
Now the only issue is with rman backups....rest are at pretty good speed.
but rman backup are still slow.
As i am not dba so i am confused to figure out the issue which i need to
fix in the rman script which is there in netbackup to do rman backup.
Regards,
atif

Hi Atif,
to be honest with only two clients this is already pretty decent
performance. The fact you have big box with a load of CPUs is actually not
going to be the deciding factor in the preformance you are seeing, the
performance will be related to the disk hardware (IOs per sec performance
is very important), HBA/SCSI controller hardware, filesystem type, file
size etc etc. As mentioned already if you are using the standard Oracle
agent this will probably not give you blindingly fast performance. If you
are still unsatisfied with the performance you could consider using the
advanced client which I think provides support for RMAN proxy copy which
may speed things up.... What level of performance are you expecting?
thanks Andy.

Thanks to all who reply to my question.
So far here are the things which i have achieved.
If i start backup of two different client I am getting 100MB per sec
on the total.
But for a single box this speed does not go above than 50. Although
there is no activity. and the box is not loaded.and its a good machine
SF6900.
