Hello and thank you in advance for any help. I've searched the forum and found similar questions but not exactly what I'm looking for. My only computer is an old Dell that runs windows XP SP2. I am planning on reformatting the hard drive and re-installing windows once I get this question resolved, ideally today. I have backed up all of the "my documents" folder to my external drive. That includes the iTunes folder, but I also permanently keep a lot of my iTunes library on the external because my PC's hard drive is very small I have the new iOS and regularly back up to iCloud I understand the advice is generally to back up your itunes library. -How much of the iPhone's data is backed up in that process? -How do I retrieve that data once I've reformatted? -What steps do I need to take to make sure that data is retrievable via the external hard drive? I'm most concerned about all the apps, bookmarks, settings, application data, text messages, etc. Thanks so much!
