Does deactivating and reactivating the SharePoint Publishing features cause data loss?

down votefavorite

In a SharePoint 2013 Site Collection and in its Subsites the SharePoint Publishing Features are enabled: SharePoint Server Publishing Infrastructure Feature (Site Collection Level) SharePoint Server Publishing Feature (Site Level)

 If deactivating the SharePoint Publishing Features and afterwards reactivating the SharePoint Publishing Features would cause any data loss to the environment.

1. What happens to the Sites, Document Libraries, Content Types that were created by the SharePoint Publishing Features? Will they be deleted by deactivating the Publishing Features?
2. What will happen to the the sites, document libraries, content types, master pages if customizations were made?
3. What will happen to the Sites, Document Libraries, Content Types, Content, ... when reactivating the Publishing Features? Will they be overwritten by reactivating the Publishing Features?
4. Will creating a backup of the content database(s) provide a sufficient fallback option if data loss is a risk?

There is no data loss associated with deactivating/activating this feature.
