I think otherwise, but if the server is not rsync capable, you must
use a different rsync call syntax (see man rsync) and the server must
have rsh or ssh which rsync probable uses to uploas an rsync server
(?).

rsync does more than that! Where the name matches but the size or
timestamp do not, it uses a very clever algorithm to download only
the differences inside the file and patch them into the local copy.
This can be VERY quick.
If you do a tree copy to the hd, then you won't find a matching tree
on the mirror to rsync on. If you want an iso CD image file, then
you should try 'dd if=/dev/cdrom of=<hd file>' from the cdrom device
to an *.iso file on your hd (warning: I have never tried this!) and
rsync on that at the server. I do not believe that the reverse ('dd
of=/dev/cdrom if=<hd file>') process works because /dev/cdrom is a
read only device - you must use cdrecord to write a CD.
