Be careful! The Appspace Intranet (Powered by Beezy) does not support undoing the deletion of Stories.
Deleting a Story deletes all the data in the database. Therefore, all images or files except text will be lost.
However, the .aspx file in SharePoint contains the raw text.
You can find the Stories stored in SharePoint by going into the Stories folder of your /stories subsites and when you find it you can recover the text from the file.
