I have a blog on WordPress (recently upgraded but have not changed the address yet); webpages on Google; and recently obtained a domain name which I have not done anything with yet. I like WordPress? Google webpages are live and I worry that I don't have back up although the first page or index is now in my Google Drive. In the past I managed web pages that were updated using software and published. I always had a copy as a result and which is good.

What is the first step? Any recommendations?
