While JoomlaCloner is decent enough, it fell short horribly when I wanted to 'clone' a client's locally created site - it could not configure the new SQL database properly. I resigned myself to either dragging modified CSS and PHP files from the local server to the FTP server, or creating the site from scratch on the remote server.
CONS: The ONLY feature I miss is the ability to exclude individual files and components from the backup process. If the developer includes this in a future version, JoomlaPack would be complete!
Please request those features on the feature request board where they will receive more attention.
