Sorry that my links weren’t helpful, I’m not quite sure what the question is.
I’ve never worked with Updraft, but I would think the basic flow for restoring a backup that was created using Updraft would be something like:
Create a new, plain site in Local
Install the Updraft plugin within the Local site
Use the plugin within the WordPress admin of the Local Site to restore the site using the backup files that it gives you.
Alternatively, if those files that are given contain a database sql file as well as the contents of the wp-content directory, then you should be able to restore the site by following the steps outlined in the “Restoring From Only Local Site files” section of this help doc:
I never heard you say you tried the first thing Ben Turner suggested. I, too, found that Local can’t handle the backups made by UpdraftPlus. BUT I started with a fresh, vanilla site; installed and activated the UpdraftPlus plugin; uploaded the 4+1 backup files UpdraftPlus made from my live site (.zips of uploads, themes, plugins, other, plus a .gz of the database) into the UP pane “Backup/Restore” (drag-and-drop into target block or click “Upload backup files”), then selected them all and clicked “Restore” . . . Voila! I had the site working in Local. Of course, I had to login again to the WP dashboard (using the credentials from my administrator account from the live site).
I’m so glad to have found this thread because I’ve been using UpdraftPlus on a lot of sites and was always stymied when trying to get them into Local. But this worked just fine for me.
