Do the files change a lot, or is it more like a few files added/changed
every day, and the bulk don't change?

If it's the latter, you could maybe get best performance from something
like Subversion (a CVS derivative).

Though I suspect rsync would also do well in that case.

If a ton of those files are changing all the time, try doing a test on
creating a tarball and then backing up the tarball.  That may be a simple
managable solution.  There are probably other more complex solutions of
which I am ignorant :-)

Like Music?
