Good question about compression.  In fact, I've just been having this
conversation with DataTools as we compared the Oracle OBACKUP support
with SQL-BackTrack.

My view is that you definitely don't want to use both SQL-BackTrack
compression and ADSM compression.  I don't have details on SQL-BackTrack's
compression algorithm, but it is more than just removing nulls....I suspect
it is similar to ADSM's support, but we haven't done any testing to compare
the results.  So, if you choose to use compression, you might try a test
with both algorithms to see which compresses your data best.

Whether you use compression or not is the same discussion for ADSM in
general.  You would reduce network traffic and storage space on the ADSM
server if you use compression, but you will increase client cpu usage.
If the client has enough cycles to handle the compression, and the network
is a bottleneck for you, it makes sense to use compression.
