That is the question: does the compress=no on the command line override the 
compress yes in the dsm.sys?  Apparently not.  The docs state, though, that the 
exclude.compression will override the dsm.sys.  Might be you only option.

Kelly,
        It is good to know an option like that exists, thanks.  But that
is not really my question.  What is wrong with what I am doing? I don't
see any mistakes in my configuration. When I create a schedule and put
"-compression=n" in the options for the schedule, the TSM client should
turn compression off for that schedule, right?  I shouldn't have to put
a special exclude in, should I?

How about exclude.compression on that filespace?  

exclude.compression 
Excludes files from compression processing if the compression option is
set to yes. This option applies to backups and archives.

Greetings,
    I have a specific NFS filesystem on a TSM AIX client that I need to
backup without compression because the files are very large and already
compressed, so it is pointless to compress them.  But compression is
"yes" in the dsm.sys file because I want to compress the other
filesystems.
    The TSM client definition for compression is set to "client", so
presumably the client can choose to either compress or not.  Here is the
dsmsched.log of the schedule.  Note that I turn off compression in the
schedule:

Why am I still getting "ANS1360I Compressed Data Grew" when the options
for the schedule are "-compression=n"?  It shouldn't be trying to
compress, should it?  
 
We are running TSM client 5.4.2.0, and TSM server 5.4.3.0 on AIX, in
case that matters.
