If you have a database associated with your host, you need to map this database. This is automatically done for you if the host was pre-installed with WordPress when creating it, or using an Extra to create the host. A check mark indicates the database is associated with the host.
Highlight a host and go to the Cloud tab for this host. Press ‘Save To’. Your host data, and exported database data will be saved to your Dropbox. You can then use the ‘Load From’ button to load this site from another Mac, or your current Mac, if your are using the Cloud Functions as a backup utility.
