Re: [ADSM-L] How do I override compression setting?

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.

Subject: [ADSM-L] How do I override compression setting?

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.
