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.
