This plugin backs up before deleting posts.
When you click “Delete Permanently” WordPress will create an XML file to save to your server computer.
The XML file is stored in “wp-content/deleted_posts” on your wordpress. 
 The XML file is stored in the site-id if your wordpress is multi sites.
The XML file is stored with a format same as Export on WordPress. 
 If you want to restore the post, you can use Import on WordPress.
Supporting post-types are “post”, “page” and “custom post”. 
 But “attachment” is unsupported.
