Manage Distant Site For Auto Export is not working

I schedule a job for distant export :

1st - the engine interface show as example : (example : http://localhost:8080/jahia/Jahia) - The new url does not content jahia/Jahia anymore ... what is the right url ??

2nd - I saved my batch, but when recalling it , all data are missing

The batch didn't work : ERROR : Export file cannot be uploaded on server

used siteadmin to export and root to import
