Lisa, my file server used to be clustered, have compressed drives, and used TSM 
baclient 5.5 for incremental and image backups and restores without issue. We 
have since virtualized it and it is no longer clustered. The drives are still 
compressed and we are still using TSM baclient 5.5 for both incremental and 
image backups and restore without issue.

I think the only thing I would caution you about is be weary of how much disk 
space you have left vs. how much you are trying to compress. I've seen drives 
fill during a compress operation because there is not enough free space to hold 
(temporarily) both the original and compressed version of the file(s) during 
the compress operation. You'll probably be fine; but, I just wanted to mention 
it.

& TSM baclient

Good Morning TSMers!

We are running really low on space on our clustered user drive.  I was thinking 
we could do the MS compression on the entire drive to get some space till we 
move to DFS on 2008.

One of my co-workers said that the reason that this hasn't already been tried 
is that there is some kind of issue with TSM-either the backups or the restores 
"don't work right".

I am unable to confirm/deny issue via Google... Anyone have anything definitive 
on this? Point me where to hunt for documentation??

I'm not coming across anything on IBM's Tivoli portal, and the issue doesn't 
ring any bells for me.



thanks!
