Shifter provides an optional automated backup feature which creates an archive of your WordPress data each time you create a new deploy.
For example, as you generate the static version of your site Shifter will create a snapshot or backup of your WordPress data as well.
If you need to restore your WordPress site with one of those backups here's how you can do that.
Restoring a WordPress backup
Navigate to the list of deploys. If a backup is available you will see a WordPress icon appear in the deploy.
Download the backup clicking the WordPress icon.
Start WordPress as normal or in safe mode if you're having an issue and you need to restore your site.
Navigate to the All-in-One WP Migration plugin page where you can import the backup.
Upload and import your backup to WordPress restoring your data.
