Backup Exec 2012 - Slow speed, even with SSD - why?

[LucasS]

Hi,

our customer is going away from competitive backup imaging software   and we installed

a san with 20 SSDs and FC attached to 2 x new phys. ESX Hosts and 10GBE ethernet to the Backup-Server from

the VMware Hosts.

As a physical symantec host we are using a Server with over 300 GB RAM

and 2 XEON with 3,xx GHz.

The landing space is  also a ssd san, because

we are waiting for the Raid10 SAS SAN with 80 SAS-Disks for

Backup purposes.

We are using the existing bought licenses of the Customer to install BUE 2012.

And Backup Exec 2012 is pulling with a max. of 50 MB/s?????

What have i misconfigured? No dedupe, no verifies etc.

Is that normal for Bue2012? Do someone else ever have seen Data rates 

of more than 50 - 80 MB/s in the last years? Someone an idea

for me before the customer recognize that.

We get 50 over nbd and 80 over SAN/FC.

The landing space gave us a benchm. of 1400 MB/s.

Iperf gave us 744MB/s from a guest to the BUE2012 Host.

Best regards and many thanks

Hi,

If you have an AV installed make sure it isn't scanning the B2D or the BE services. If so, put in an exclusion and then try the backup again.

Do you get this speed if you try to backup the local server? You can test connectivity between the media server and any remote servers by copying data from the remote servers to the media server and to the drives that the B2D is located on.

Thanks!

Hi CraigV,

the environment is fresh and there is no AV agent
on the physical backup host.

I am getting the speed when i am using the VADP (AVVI) Backup method.

- NBD= 50 MB/s
- FC= 80 MB/s

Note that source, target-landing-space and transfer media (10 GBE/ 16Gbit FC)
are not possible bottlenecks. They have been gebenched. And SCSI-Queues
are also empty. 

No idea. Do you see values greater than mine in your time with BUE?

Thanks

I recently had this problem occur with AV.  It dropped my backup speed from about 1400MB/m to 50MB/m.  I turned of AV, and the problem went away.  The notable part here was:  I was using SYMANTEC EndPoint Protection 12.

Another issue I have had, was with my network card, and that was that I had to turn off the IPv4 Checksum offload feature, because when it was on, it would kill the speed of the transfers.

If you've done a normal file copy, and it gives you some tremendous speeds, maybe try some simple backups of the host system to the backup storage, to see where the speed is being lost, and eliminate other issues.

Also make sure you have the latest patches for BE12, should be SP3, and make sure you have pushed all those patches out to your clients.

Good luck.
