How to make live archive of wordpress site
I'm very new to Wordpress and need some help. I am currently running a Conference website through Wordpress.org on my own domain through godaddy. Since this is an annual conference--- right now, last year's conference is listed on it. Before I edit the website for this year's conference, I want to archive everything that's on the website right now to a live link, just so that myself and future people can reference it.
What is the best way to go about this?
Do I have to export the current website files to the FTP folder or is there a better way to archive?
