Commit your changes on your local machine then SSH to your server and do an svn update.
one problem with this method, is that your web directory will have all of the .svn folders sprinkled throughout your subfolders. svn export avoids this issue.
You can also set your webserver to ignore the .svn folders.
... but export can waste a lot of time and bandwidth if your project is large ;-)
I'd recommend that you look into SVN export command
