Features can export everything? Built all blocks, menu, taxonomies, view etc in Drupal CMS on localhost machine, but I need to export everything to the live server. Is it possible to use features or just export sql?
The Features module allows you to export all the configurations in code (instead of DB). It is very usefull when you have 2 separated versions of database, in example one for your localhost or test installation, and one for your live/production website.

However, if you want to deploy the local database to the live server too, it is not necessary to export everything with Features.
