The scaling side of things just trades a little more CPU for
compression and rsync-in-perl in return for vastly less disk
consumption so it's not a sure bet either way in that respect.  I
think you've mentioned some subsequent off-line archiving scheme for
your data sets that wouldn't mesh very well, though.   But, everyone
has lots of other stuff where backups would be nice to have and
backuppc makes it trivial to have, say, daily copies of all of /etc
from all machines going back months - or your own home directory.
And it doesn't blow up if you point it at a bunch of home directories
where developers have checked out copies of the same big source trees.
