Ditto, I use a similar approach. 
I have them in a client option set on the backup server so they can be easily 
managed in one location.

Subject: [ADSM-L] "Compressed data grew" retries?

I have been watching an initial TSM backup running for a long time now over a 
WAN connection (100mbit/sec) and I keep seeing "compressed data grew"
followed  by a "Retry".  Does this mean that for every file that compression 
increased the size (even 1%) the whole transfer is discarded and it starts over 
again with the same file (presumably with compression disabled)?  If so that is 
probably hurting my backup speed much more than the compression ever improved 
it.  Is there any way to prevent this short of adding one of these options for 
every type of compressible file?
