Hi Zoltan,
There's a section in the BA client user guide that talks about the options 
available for backing up Microsoft DFS, perhaps that will help.... it's a short 
read. I haven't used it in a few years so would be reluctant to be specific on 
usage.

(from page 180 on the 7.1 version of the BA guide)

There are the methods you should use to protect your Microsoft Dfs data:
        1. Back up the Dfs link metadata and the actual data at the share 
target of each
        link from the workstation hosting the Dfs root. This method simplifies 
back up
        and restore by consolidating all of the Tivoli Storage Manager 
activities on a
        single workstation. This method has the disadvantage of requiring an
        additional network transfer during backup to access the data stored at 
link
        targets.
        2. Back up only the Dfs link metadata that is local to the workstation 
hosting the
        Dfs root. Back up the data at the target of each link from the 
workstation(s)
        which the data is local too. This method increases back up and restore
        performance by eliminating the extra network transfer, but requires 
Tivoli
        Storage Manager back up and restores to be coordinated among several
        workstations.

Hope this helps......

We were able to determine it was a rights issue on the Isilon system.  TSM 
needs root-level access.

However, our current problem is how TSM backs things up when using DFS mounts.  
Eventhough we specifically say to backup "\\rams.adp.vcu.edu\vpa\vp 
administration\*", the only filesystem TSM sees and registers when it backs up 
is the highest level, that being "\\rams.adp.vcu.edu\vpa" - it ignores the "vp 
administration" sub-directory/folder.

Does anyone out there have experience with backing up DFS with TSM?  Is
this the way it is going to be?   This is back to each
department/group/area wanting total control over backup/restore of their 
"shares".
