Thoughts On WordPress 2

I was imagining the site is crashing or there is a glitch.  Then do we lose all the written memories of our journey? Does WordPress secure and back up all the blog sites somewhere? Will our posts be read by future generations?!  Is there a feature where every blog we post automatically gets sent to our personal email address just to have a back up?

Hoping to get a feedback or suggestion. I was thinking of copying and pasting all my posts so I can have my own copy. I just thought of this now. It means I have to go back in November.
