Backing Up iPhone
iTunes creates backups of settings, downloaded apps 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. See “Updating and Restoring
iPhone Software” on page 256.
Backing up iPhone or restoring from a backup isn’t the same as syncing content and
other items (such as music, podcasts, ringtones, photos, videos, and apps that you
download via iTunes) with your iTunes library. Backups include settings, downloaded
apps and data, and other information on iPhone. After you restore iPhone, you need to
sync again to get your music, videos, photos, apps, and other content back on iPhone.
See “Restoring from a Backup” on page 257.
Apps downloaded from the App Store are backed up the next time you sync with
iTunes. Afterwards, only app data is backed up when you sync with iTunes.
Creating a Backup
iTunes creates a backup of iPhone when you:
Sync with iTunes Â
By default, iTunes syncs iPhone each time you connect iPhone to your computer.
See “Syncing with iTunes” on page 53. iTunes won’t automatically back up an iPhone
that isn’t congured to sync with that computer. You can also sync manually by
clicking Sync in iTunes. Note that iTunes creates a backup only once each time
iPhone is connected to your computer, before the rst sync that occurs. If you sync
again, iTunes doesn’t create another backup.
Update iPhone Â
iTunes backs up iPhone before updating iPhone, even if it isn’t congured to sync
with iTunes on that computer.
Restore iPhone (if you choose to back up) Â
iTunes asks if you want to back up iPhone before restoring it.
For more information about backups, including the settings and information stored in
a backup, go to support.apple.com/kb/HT1766.
