NetBackup Copilot for Oracle - its performance

[quebek]

Hello

I am wondering what are the speeds you are achieving with Copilot for Oracle on NBU appliances - I am specifically taking about Backup from Snapshot step (its copying the data from share to msdp on the same appliance) - in configuration with NetBackup Copilot with Oracle Accelerator (Oracle's Incremental Merge). In environment I do manage we do have 3 such backups configured. Each is using its own NBU appliance, two streams, NBU appliances are 5250's and I do see such speeds for this Backup From Snapshot step:

• 700 MB/s
• 396 MB/s
• 308 MB/s

So out of these three appliances only one is performing well and its a benchmark for the other two which are not even close to first one.

I am wondering what values you are seeing in your environment. Please share if you can.

Also I am wondering how NBU 5350 could have improved above backup approach - as 5250 can only have standard share - while the 5350 optimized share. What is the benefit of the optimized share?

Hello 

Small update for interested ones.

After having long lasting case with Veritas now we see throughputs like 1160 MB/s in the same step for the one which had only 308MB/s so now it is 3.7x faster it used to be.

What did the trick is describe here (for me this worked out well ftrunc_up_zfod_alloc=33554432):

Unfortunately I had to expire the backup images already stored on this file system (nfs shared)
