We had this problem as well. We have a Windows 2008 server that has an X Drive 
that has 1.2TB worth of 100k files. We solved this by creating a another 1.2 TB 
lun and use Windows Server Backup to back up the X Drive to the new drive. We 
then use Networker to backup the new Drive. It took our backup from 72 hours to 
7 hours. Plus we now have an onsite backup because of the disk to disk to tape 
solution. 

Thanks
Craig

It sounds like you've got a dense filesystem issue. I've got examples of how it 
can affect backup performance in this blog article - 
http://nsrd.info/blog/2009/06/17/in-lab-review-of-the-impact-of-dense-filesystems/

Generally speaking your two options are likely to be:

(a) Multiple savesets;
(b) SnapImage.

If the directory layout on your D: drive is such that it's somewhat balanced, 
and the root directories are unlikely to change, you'll likely get the 
performance improvement you want via option (a). However, that'll depend on the 
layout of your underlying disks - presumably it's RAID? If so, then you should 
be able to support at least two concurrent read sessions, maybe more depending 
on the type of RAID and the speed of the drives.

Cheers,
Preston.
