Incrementally updating a remote joomla web site?
===

I have a Joomla 1.5 site on my localhost. It's hosted on a public hosting server as well. 

I was wondering what is the best way to do incremental updates to the site? I mean I don't want to update the whole site, if I just changed one source file (html, php, images, etc) or made changes to the database. I understand, to be safe I'd have to update the database every time (export from local and import in remote), but I'm sure we can avoid unnecessary uploads of unchanged files.

I've seen https://www.akeebabackup.com and it doesn't offer what I need. One option is to use an ftp client (like Filezilla) which does folder synchronizations, but I'm not sure they work very well.
