Backing Up iPhone
iTunes creates backups of settings, downloaded applications and data, and other
information on iPhone. You can use a backup to restore these items to your iPhone
after a software restore or to transfer the information to another iPhone.
Backing up iPhone or restoring from a backup is not the same as syncing content
and other items (such as music, podcasts, ringtones, photos, videos, and applications
that you download via iTunes) with your iTunes library. Backups include settings,
downloaded applications and data, and other information that resides on iPhone.
You can restore these items from a backup using iTunes, but you may also have to sync
your iTunes library content again.
Applications downloaded from the App Store are backed up the next time you sync
with iTunes. Afterwards, only application data is backed up when you sync with iTunes.
Creating Backups
Backups can be created in the following ways:
Once iPhone has been configured to sync with a particular computer, iTunes •
automatically makes a backup of iPhone on that computer when you sync. iTunes
won’t automatically back up an iPhone that isn’t configured to sync with that
computer. If you’ve configured iPhone to automatically sync with iTunes on a
specific computer, iTunes will back up iPhone every time you connect it to that
computer. Automatic syncing is turned on by default. iTunes only makes one backup
each time you connect, even if you sync multiple times before disconnecting.
If you choose to update the software on iPhone, iTunes will back up iPhone
•
automatically, even if it isn’t configured to sync with iTunes on that computer.
If you choose to restore the software on iPhone, iTunes asks if you want to back up
•
iPhone before restoring.
If you use a Bluetooth headset or car kit with iPhone and you restore settings,
you must pair the Bluetooth device with iPhone again to use it.
