Using Command

rsync -avzP --delete --omit-dir-times ../../ [email protected]:/var/www/mysite/

I'm getting

rsync: mkstemp "/var/www/mysite/.." failed: Permission denied (13)

If ext is in the www-data group should I still set all the files to be owned by user www-data? I am trying to publish the files with rsync and then set the permissions using

 sudo chown -R www-data doc
 sudo chgrp -R www-data doc

but I can't even rsync because of the permission denied. The SSH works fine, the rsync too except when it tries to write over or update some of the files in /var/www

Server

I have already configure this http://stackoverflow.com/questions/2124169/cwrsync-ignores-nontsec-on-windows-7

This article has also managed to confuse me http://unix.stackexchange.com/questions/41687/how-should-i-rsync-files-in-var-www-if-i-want-them-to-be-owned-by-www-data

What is the right procedure?
