5220 Backup performance

Question

Hello,

&nbsp;

My setup as follows:-

&nbsp;

Master Server

5220 Appliance / Version 2.5.2 / NetBackup Version 7.5.0.5 / 2 x 10Gb/s Bond

Client Server

Solaris 10 SPARC Server / 7.5.0.5 NetBackup Client / 10GbE network

Data that is being backup up ( Oracle / SAP database files. Typically 10GB is size per file )

&nbsp;

The performance that I achieve for my backups is not very good.&nbsp;For one particular backup, I&nbsp;typically kick off 10x backup streams, on average 15000 KB/s per stream. That equates to approx 2.5 hours to backup around 1 TB of data.

On another NetBackup environment, I backup the same data to a SL3000 library in approx 20-30 mins

&nbsp;

I have noticed that the 5220 job reports the following:-

06/18/2014 21:00:50 - Info bptm (pid=14000) waited for full buffer 250973 times, delayed 262027 times

&nbsp;

Is there any tuning that I can do on the 5220 appliance to get these buffers vaules down ?

&nbsp;

Any advice on tuning will be appreciated.

&nbsp;

Thanks

Warren

Hi Warren,

&nbsp;

Hope you're doing well. What are the buffer settings on the appliance? The waits are very high.

&nbsp;

Have you copied (ftp not scp as learnt) form the client to the appliance. What speed do you get on a data file.

&nbsp;

Please post the result.

Hello Riaan,

&nbsp;

I am waiting for my security team to open the firewall for FTP test. I will revert with that when I have access. I thought these settings are&nbsp;"tape" related

Hi Riaan,

&nbsp;

I am waiting for the firewall guys to open FTP for me to run that test.

I will revert back with the results when I have access.

I thought these setting are "tape" related;-

You can use GEN_DATA file directive to performance test the Netbackup installation.

GEN_DATA file directive will generate random data streams in memory and is really one of Netbackup hidden gems.&nbsp;

I suggest you take a look at this technote:

Hi Warren,

&nbsp;

Those defaults should be sufficient. The fact that the wait was so high would indicate to me that the data is arriving to slowly across the network.

&nbsp;

Why are you going through a firewall? What is the speed of the ports on that?
