SBS2003 / Acronis True Image Server / USB Drivers Question
Posted on 2006-11-15
Not specifically an SBS based question, but it's related to an SBS installation so there seemed no better place to ask this question ...
I'm trying to use Acronis True Image Server to backup to an external USB2.0 drive. When its in progress, I get critical performance alerts from the server as it takes 95-100% of cpu time. The priority is to LOW. I have yet to get a backup to complete ...
I can back up to the same USB drive from XP Pro using Norton Ghost and I get no such similar problems. The XP PC remains responsive and the backup completes in an acceptable time.
Now, either True Image Server 9 is rubbish, or there's a server issue.
In looking at the drivers for the USB ports on the server, there are 4 instances of USB Universal Host Controller, and 1 instance of USB Enhanced USB2.0 Controller. The motherboard is an Asus P4C800 Deluxe and features 4 rear USB2.0 ports and 2 front panel USB2.0 ports. The usb drive is connected to an external port.
Assuming that part of the issue is that data is being transferred at USB1.1 speeds, I have a few questions :
1. How can i identify which physical port(s) are installed as usb 2, and which as usb 1.1 ?
2. Why aren't all the USB controllers installed as enhanced (usbehci.sys) ? I have tried updating the drivers for the controllers not installed as USB2, but it won't let me (not without warning that they are the wrong drivers at least).
3. Any comments appreciated ...
I'm running 2003 SBS Service Pack 1.
