I was under the impression that when I back up my iPhone with iTunes on Windows 10, everything is backed up, so that I can restore everything to a brand new iPhone.
iTunes iPhone backup size (6 GB)
However, when I look at the backup folder size at
C:\Users\<username>\Apple\MobileSync\Backup
it's only 6 GB.
Used storage on the iPhone (40 GB)
When I check the "storage" section on the phone, music alone is 9 GB, let alone another 14 GB of app data, photos etc.
Also, when I check iTunes, it shows "Documents & Data" being around 25 GB.
Discrepancy (32 GB)
Therefore, I was wondering, what's missing in the iTunes backup?
My research so far
I've googled for https://www.google.com/search?q=what+does+itunes+backup+include
and found articles saying "photos" and "music".
https://www.imobie.com/support/what-does-itunes-backup.htm
But that can't be true in my case. Or I'm missing something.
I've also not found any settings where I could configure what to include in the backup and what not. So I'd assume the entire iPhone would be backed up including the operating system and all the apps and all the data.
Versions
- Windows 10, version 2004
- iTunes version 12.11.0.26 (directly downloaded, not via the Windows app store)
Best Answer
straight from Apple themselves, as the first result on your Google search;
your backup data should be located, by-the-by, at
%appdata%\Apple Computer\MobileSync\Backup\
.the TL;DR is that a full iPhone backup will only actually back up data and settings important to the iPhone, such as keyboard layouts, dark/light mode settings, language preference, and more.
to back up your photos, music, contacts, and whatever "other" is classified as, you're looking for backing up with iCloud, which (unless manually disabled in Settings) is automatically done.
