If you go to that folder, then enter Time Machine, you'll be able to see older backups. You can try restoring one prior to the most recent one and see if it's usable. Make sure to replace the current backup with an old one or, if you keep the current backup, change its name so that Time Machine restores the older one with exactly the same name. You should also think about backing up your iOS device to iCloud every now and then. I discuss iCloud backups in this article from last year. Having both a local iTunes backup and an iCloud backup may seem redundant but in a case like this, it might be just what you need.
Where are my chapters?
Q: I recently downloaded an audiobook of Moby Dick. It's rather long, and it's split into over 100 chapters. While these chapters display in iTunes, they do not appear on my iPhone when I play the audiobook. I loaded the audiobook onto a five-year old iPod nano, and it shows the chapters. How can I get access the chapter information when playing back the audiobook on my iPhone 5?
This can be confusing for people who don't often listen to audiobooks. Here's some clarity. When playing audiobooks, iTunes can display both chapter and parts information. You'll see the parts an audiobook contains by clicking on its icon in iTunes' main window. These are the separate audio files that make up the book. But if you double-click an audiobook and start playing it, look in the menu bar and you see the Chapters menu, which lists the book's chapters — the audio that equates to the chapters in the printed form of the book.
iOS 7's Music app displays parts but not chapters. You access a list of parts by tapping on the List button in the top-right corner of the Now Playing screen. Earlier versions of the Music app gave you access to chapters, but Apple removed that feature (unfortunately) with iOS 7 on the iPhone (and it was removed long ago on the iPad). I found it useful to know how long a chapter was, which is something you can't easily find out now. The only thing you can do is navigate from chapter to chapter by tapping the Forward and Back buttons. You'll see the name of each chapter after the author's name, but nothing more. For example, you won't see the length of each chapter, which you did see in the past.
The reader didn't say if they had bought this audiobook from the iTunes Store or from Audible. If it's the latter, using Audible's own app lets you view a chapters menu. It also lets you save bookmarks and change the speed in more increments than the iOS Music app. Audible's books can be cheaper than the same books from Apple — you can get a book-a-month plan for $15 a month, and other plans can cost even less. If you're a big audiobook listener, Audible is the better deal.
