Complaining to the Support Center is sometimes very effective. I
complained a couple of years ago about the requirement that dumps be
sent in COPYFILE packed format. After I gave them the numbers for one of
our dumps packed by COPYFILE vs. VMARC, and indicated that our
development network apparently wasn't the fastest thing around, they
agreed that much smaller is better. They started accepting VMARC packed
files.

We are investigating the issues surrounding dump compression and 
encryption for the VM environment.  It is my hope, though, that the 
solution to these problems will be more generally useful.

Of course, if you're aren't having trouble getting data to the Support 
Center, or aren't complaining (to the Support Center) if you do, then I 
guess we don't have a problem to solve, and can move on to something
else, 
eh?  ;-)
