Okay. It’s a great idea to back up your site. After I deploy my Publii site to Netlify, I ran a back up in Publii app. I went in my Publii back ups and extract the back up zip folder and copied the folder to Publii sites folder. Then, I opened Publii app and it displayed the add a website (cause I delete everything). Then, I click the 3 arrows in the top right corner, clicked on Themes, and then, I click Go Back and my site appear with server details.
