108 Appendix A Troubleshooting
Backing Up iPod touch
iTunes creates backups of settings, downloaded applications, and other information
on iPod touch. You can use a backup to restore these items to your iPod touch after a
software restore or to transfer the information to another iPod touch.
Backing up iPod touch 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 other information that resides on iPod touch. You can
restore these items from a backup using iTunes, but you may also have to sync your
iTunes library content again.
Creating Backups
Backups can be created in the following ways:
Once iPod touch has been configured to sync with a particular computer, iTunes Â
automatically makes a backup of iPod touch on that computer when you sync.
iTunes won’t automatically back up an iPod touch that is not configured to sync
with that computer. If you have configured iPod touch to automatically sync with
iTunes on a specific computer, iTunes will back up iPod touch 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 iPod touch, iTunes will back up iPod touch
Â
automatically, even if it is not configured to sync with iTunes on that computer.
If you choose to restore the software on iPod touch, iTunes asks if you want to back
Â
up iPod touch before restoring.
