Backup Exec 2010 Throuhput Rate is Slow


I am using Backup Exec 2010 R2 to perform full backups on all of our servers once a week and then differential backups
throughout the week.

We are a 24/7 company and  due to the vast amount of data I am finding it difficult to complete the full backups
under 24 hours so that the differentials are able to run the next day.

All of our servers have gigabit network cards and a link speed of 1Gbps, however, when I am backing up the Windows system
drive I get an average throughput rate of 209MB/min. How can I speed this up? Or is this a normal speed for backing up Windows?

I have tested the network on one of the servers by copying a 1GB file to and from the Backup Media Server, the file was
copied in 55 seconds.

There can be many reasons for a slow throughput and would require investigation.
To start with check if you the throughput is dropping due to a very slow backup of System State or Shadow Copy components on a Windows 2008 server as that has been seen to cause a drop and is currently under investigation by Symantec .

Refer to the following article for pointers to further investigate the issue.

Please check the related articles listed in the above stated TNs too.

I think I have found the bottleneck... If I disable the antivirus software on the remote server I get an average throughput rate of 790MB/min.

However disabling the antivirus is not a solution.

I have tried to exclude the following directories with no success:

C:\Program Files\Symantec\*.*
C:\Backup Exec AOFO Store\*.*
C:\Documents and Settings\All Users\Application Data\Symantec\*.*

The problem seems to be that the antivirus software (ESET) is scanning the "\Device\VSPSnapshot\" objects during a backup.

How can I exclude this?

Check out the user guides at the following location for the correct version and that should provide you with more information on setting up the exclusions.
