man rync : -n, --dry-run show what would have been transferred
rsync -aHv -n --delete --bwlimit=512 rsync://mirror.centos.org/cAos/centos/4.0/ /path/on/your/server/to/your/centos/4.0/dir/
Thanks. I didn't think of doing a dry run to determine that. I guess I should have. I did man rsync before I ran the command though.
