Slow throughput with remote agent (BE 9.1 SP2) SBS 2003

[Tom_Purnell]

I am experiencing a problem with Backup Exec. The problem is that backups from a remote server seem to run very slow unless I reboot the remote server immediately prior to the backup. My configuration is shown below:


Server 1 (Main Server):

Dell PowerEdge 2850 (dual 3.2 Xeon, 4GB RAM)
Windows 2003 Small Business Server Premium (Exchange 2003 in use)
Backup Exec 9.1 SBS Edition with Service Pack 2 installed
Dual Teamed Built-in Intel Network Cards
Dell PowerVault 122T LTO2 AutoLoader connected via. Adaptec SCSI card
Mcafee Virusscan 8.0i Anti-Virus software
Mcafee Groupshield Exchange Anti-Virus


Server 2 (File/Print and Fax Server):

Dell PowerEdge 2850 (dual 3.0 Xeon, 2GB RAM)
Windows Server 2003 Standard
Backup Exec 9.1 SP2 remote agent
GFI Faxmaker Fax Server software
Dual Teamed Built-in Intel Network Cards
Mcafee Virusscan 8.0i Anti-Virus software


The problem is that the speed of the remote backup is very slow unless I reboot server 2 immediately before the backup takes place. The throughput I achieve is around 1000MB / min if I do the backup immediately after a reboot but if I do it a few hours later or at the end of a days use (I normally run the backup at 11PM) the throughput falls to around 40MB / minute! I'm sure there must be an underlying cause but the only solution I have found so far is the reboot!

I disable the virus scanner with a Backup Exec pre-backup script on both servers. I have tried the following:

Restarting the remote agent immediately prior to the backup (no effect)
I have tried restarting the backup exec services on server 1 prior to the backup (no effect)
I have set the Network cards to Auto 1000Mbps rather than auto-negotiate (no effect)
I have told the main backup exec server which network interface it should be using under options / network (i.e. the teamed connection) - no effect
I have tried completely uninstalling and then reinstalling Backup Exec Server and agent + reapplying SP2 - this had no effect

Is there anything else I can try?

Thanks for your help

Hi'

There are number of steps to be followed,

1)Are you using AOFO.
Kindly refer to this technote:-
http://seer.support.veritas.com/docs/263139.htm

2)This could be a network related issue aswell.
Try Copying any large folder from the remote server and check the throughput.

3)Try performing a backup job on backup to disk folder so that we can make sure it is not a device related isue.

4)Check the version which is being used on the remote server for the compatibility issue.

Trying out these steps would hopefully resolve your issue.

Thanks

Hi Javed,

Thanks for this information I will try out the suggestions you have made and post the result. I am not using the advanced open file option - does this mean that the hotfix you mention in point 1 would not apply?

Thanks
