Re: [Veritas-bu] Slow backup speed

2010-05-11 Thread John Meyers

Hemant,

are you using FC or SATA drives on the 6140 S-vols?  Also assuming this is
virtualized behind the 9990V in order to use ShadowImage.  I'd probably
recommend some testing independent of NetBackup to see how fast you can
pull data off these volumes.  Such as use something like ufsdump, tar or
cpio output to /dev/null and watch the transfer rates with something like
"iostat -xcn 3".  If that looks good try manually allocating one of the
LTO4 drives and check the raw write speeds to the tapes in a similar
fashion.  If both check out ok then it's most likely a NetBackup tuning
issue.  Either way, at least you'd know where the bottle-neck is at
that point.

Hope this helps.

John

Re: [Veritas-bu] Slow backup speed

2010-05-11 Thread Shekel Tal

Did you restart the netbackup daemons/services after making the change?

Do you still have the copy mounted?

If so it may also be worth running a test using only 1 LTO-4 drive and
see if the performance increases.

HI

 

I am facing problems in backup speed for backing up SAP databases.

 

My setup is as follows

 

I am using shadow image ie split sync for backing up my SAP
databases.The datasize is approximately 13TB.

 

My PVols are mounted from Hitachi 9990V storage and are attached to Sun
M9000 server.

 

My Svols are mounted from Sun storage 6140 and are attached to Sun T5220
which is configured as media server in veritas netbackup6.0.

 

I have L1400 Tape Library from which 4 LTO4 drives are presented to
secondary server from which backup is taken,

 

Average speed per stream is 30MBPS which makes overall throughput of
4*30=120MBPS.backup time is around 36 hours.

Have you tuned you NetBackup buffers?

Have a look at the following technote and setup the size and number data
buffers - http://support.veritas.com/docs/183702
<http://support.veritas.com/docs/183702>



Are you using agents and mounting the image up after the split or just
performing a cold flat file backup after the split?

HI



I am facing problems in backup speed for backing up SAP databases.



My setup is as follows



I am using shadow image ie split sync for backing up my SAP
databases.The datasize is approximately 13TB.



My PVols are mounted from Hitachi 9990V storage and are attached to Sun
M9000 server.



My Svols are mounted from Sun storage 6140 and are attached to Sun T5220
which is configured as media server in veritas netbackup6.0.



I have L1400 Tape Library from which 4 LTO4 drives are presented to
secondary server from which backup is taken,



Average speed per stream is 30MBPS which makes overall throughput of
4*30=120MBPS.backup time is around 36 hours.



Thanks and Regards
