There is an app on the app store named [Note2Txt](https://itunes.apple.com/us/app/note2txt/id1103045981?mt=12) that will convert each note to a text file and save it to a directory/folder of your choice. The app is $0.99 and is extremely fast and efficient. I back up my notes using this app. Each text file is given the name of the note with extension .txt
