Sharepoint - Save site as template in SharePoint 2013
Open you Team Site in SharePoint Designer 2013.
In SharePoint Designer, under Sites tab select “Site Options” Find SaveSiteAsTemplateEnabled in Site Properties set to "true".
Now in your Publishing site navigate to http://sitename/_layouts/15/savetmpl.aspx
and you would see the old Save Site as Template Page
If you are using the Publishing site template then this option will not be available. Also if you have a team site with Publishing feature activate on it then this options will disappear.
Another thing, Save as Template option is not supported for publishing sites even if you are able to save it.
You can hack the url and directly go to this URL http://sitename.com/_layouts/savetmpl.aspx
