Professional grade rsync?

[King, Daniel]

Hi, folks.

We've gone where no man has gone before.  On HP-UX, rsync bombs at about
1.75 million directories, files and links (combined sum) in a single
transfer.

Is there a professional-grade alternative on HP-UX for folks willing to pay
for it?  It wouldn't even need to be network-aware, just from single-system
areas to the same box, but with the nifty delete and update features that
rsync has.  My searches turn up unison and some other tools (BSD mirror,
etc.), but rsync has beaten any other open-source solution hands down on the
scalability side of things.  Now, we need more ...

Thanks,
