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?
