A slow throughput is observed while running backup of a server that has Trend Micro's OfficeScan realtime scan feature is enabled
A tape based or disk based backup of a server running Trend Micro OfficeScan has been observed to run at a slow throughput rate. This has been determined to be a conflict of the backup job and the 'Real time' scan of the files being accessed by Backup Exec during the backup.
On Windows 2003 and 2008 Standard Server Edition, with TrendMicro 10.0 and 10.5 the following TrendMicro settings will resolve the issue:
1. Log into the Trend Micro Office Scan Master Console. Navigate to: Networked Computers > Select/Highlight Office Scan Server > Settings
Select Real Time Scan Settings from the drop down menu > Make sure you are on the Target tab >
Change Scan Files being: "created/modified and retrieved" to "created/modified"
Left-click the Apply to All Clients button to update clients
2. Stop the Aegis TMBMSRV service. Use services.msc to stop unauthorized change service or sc stop tmbmservice.
Unload Trend Micro to stop services.
AEGIS service will no longer receive any file events that causes a drop in performance.
4. Restart the System.
Note: The Registry change must be applied on the Media Server as well as on the remote Servers being backed up.
