Slower Processing Rate after Upgrade to 9.5

Veeam Logoby NotMyDay » Wed May 03, 2017 9:29 am 1 person likes this post

Hi at all!

Until last Sunday we used B&R 9.0 on a physical Backup-Server (1x Xeon E3-1220v3 @ 3,1Ghz, 16GB RAM) without any problems.

Because of a planned upgrade of the vSphere environment to 6.5, I wanted to upgrade B&R to 9.5 first.

At first I don't realized it, cause there are 4 concurerent tasks configured that the maximum Processing Rate is between 50MB/s and 60MB/s.
But after starting a single job with 1 VM the Processing Rate is at peak at 25 MB/s (Bottleneck Source) and the CPU is bored at 30%. In Version 9.0 the Rate was also at 50MB/s.

The three nodes with the VMs running on have the following specs:
-- 1x E5-2650V3, 128GB RAM, 1x LSI SAS HBA, 1x SSD 400GB, 2x SAS3 HDD, 2x NIC 10GBit, 2x NIC 1GBit
-- VSAN Cluster via 10 GBit Switch

Do you have any ideas what I can do, because there were no configurations after the upgrade.
I am on the brink to reinstall V9.0.

Many thanks at all for your help/feedbacks

Could you please check that the same transport mode is being utilized after the upgrade (what is it, btw?)?

The transport Mode is at Automatic selection.

Proxy and Repository are the same machine.

The path of the To-Disk-Backup also the same server.

What transport mode is effectively utilized during processing? You can check in the job session log, if you click the particular VM to the left and look for the proxy server name, there will be a transport mode [tag] right after it.

You are right, I had to specify it.

The transport mode is Network, cause of "Using backup Proxy x.x.x.x for disk Disk 1 [nbd]"

NBD should be faster on 10Gb network, indeed. Nothing has changed in this area in v9.5, as far as I know, so I recommend contacting support for a closer look.

Hi Alex,

Does the below mode is NBD:

6/05/2017 6:22:54 PM :: Unable to hot add source disk, failing over to network mode...

Which is the slowest backup mode ?

Depends on the network speed mostly. However if you are facing the same issue then please also open a case to see if there may be a bigger thing ongoing which needs to be resolved.
