i did it like this:

rsync -vaH --delay-updates --delete --delete-excluded --exclude="alpha/"
--exclude="ia64/" --exclude="s390/" --exclude="s390x/"
eu-msync.centos.org::CentOS /store/public/mirrors/centos.org/

first you should get the whole list, without any exclude, and with the
"--dry-run" option to rsync, then you go thru the list, and exclude
everything you don't need with the --exclude options.

and 'man rsync' :)

and if you want only the 4.4, you can go like this:

eu-msync.centos.org::CentOS/4.4/ /path/to/centos.org/4.4/
