Fellow TSM's

As a TSM newbie I am having some difficulty configuring an incl excl list.

(Windows Client 4.1.3 to Windows Server 4.1.0)

I want to backup a single directory on the D drive of a client and want to 
exclude everything else on both C and D drives.

My incl_excl file looks as follows:

include "d:\data\*"
exclude "c:\*"

I have also tried the following:

include "d:\data\*"
exclude "*"

The first combination backs up everything and the second one backs up nothing.

Some help would be greatly appreciated.
