I have x64 windows 2008 R2 domain controller running on a VM with Symantec Backup Exec Remote Agent Utility installed.

Every night when backups run my nagios warns me that CPU utilization is 96% for about 3-4 hours while the backup is running. The offending process is of course beremote.exe. Symantec should only be backing up active directory and group policy from this server and I also have another domain controller with identical specs where beremote.exe does not kill the CPU in this manner.

Does anybody know of a hotfix for this particular issue? The only one I have found only applies to server 2003. I have also ensured that Backupexec is completely updated. Any ideas?

Edit:

Updating the Symantec Remote Client to the latest version did not fix this issue.

  • Have you tried uninstalling and reinstalling the client? – GregD Oct 06 '11 at 15:28
  • I have not. I will try that and see if it fixes the issue tonight. –  Oct 06 '11 at 15:28

    How big is your AD DB? 3-4 hours to back up AD and GPOs seems like an abnormally long time. – HostBits Oct 06 '11 at 15:44
  • What makes this server unique from the server with the same specs? Do you have any other filter drivers to worry about (anti-virus, encryption)? How's your VSS looking? Do any system events correlate? Additionally, although an API hook will greatly increase latency to the subsystem, may I suggest monitoring file system IO to see what file is "holding up" the backup process (I agree with Cheekaleak, so what's actually going on)? – mbrownnyc Oct 06 '11 at 15:44
  • The only thing that is unique is that this server has Group Policy and the other one does not. –  Oct 06 '11 at 17:07
  • And... answers my other questions? – mbrownnyc Oct 06 '11 at 20:50
  • We have been having power issues lately so I haven't had a chance to look at this. –  Oct 07 '11 at 16:04

Problem was the server needed several critical Windows 2008 R2 patches. After applying these patches beremote.exe does not even exceed 50% of the CPU usage. Thanks for all the help and suggestions.
