Please gimme a simple solution.

please don't give any advanced solution. Previously i was using simple ftp file zilla. Now i m using cyberduck(as feel good) for sftp.

EDIT

I a using git for version maintenance.

1. You can use FTP or SFTP like now, because you must set settings to upload only new or changed files.

2. If you want use some solution dedicated for this problems, you can use SVN (subversion), you can commit changes on developer machine and do checkout on server machine and server was download only changed files. And you have in this solution version control, you can revert your web application to what version you want.

You can use rsync, to only upload changed files.

Alternatively, you can upload the new version to a different directory and then switch a symlink or change a configuration file, so that you change to the new version instantly.
