Apple iPod touch iOS 4.3 - Manual (Page 215)

Backing up iPod touch or restoring from a backup isn’t the same as syncing content
and other items (such as music, podcasts, photos, videos, and apps that you download
via iTunes) with your iTunes library. Backups include settings, downloaded apps and
data, and other information on iPod touch. After you restore iPod touch, you need
to sync again to get your music, videos, photos, apps, and other content back on
iPod touch. See “Restoring from a Backup” on page 217.
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 iPod touch when you:
Sync with iTunes Â
By default, iTunes syncs iPod touch each time you connect iPod touch to your
computer. See “Syncing with iTunes” on page 45. iTunes won’t automatically back
up an iPod touch that isn’t configured 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 iPod touch is connected to your computer, before the first sync that
occurs. If you sync again, iTunes doesn’t create another backup.
Update iPod touch
Â
iTunes backs up iPod touch before updating iPod touch, even if it isn’t configured to
sync with iTunes on that computer.
Restore iPod touch (if you choose to back up)
Â
iTunes asks if you want to back up iPod touch before restoring it.
For more information about backups, including the settings and information stored in
a backup, go to support.apple.com/kb/HT1766.
Removing a Backup
You can remove a backup of iPod touch from the list of backups in iTunes. You may
want to do this, for example, if a backup was created on someone else’s computer.
Remove a backup:
1 In iTunes, open iTunes Preferences.
 Mac: Choose iTunes > Preferences.
 Windows: Choose Edit > Preferences.
2 Click Devices (iPod touch doesn’t need to be connected).
3 Select the backup you want to remove, then click Delete Backup.
4 Confirm you wish to remove the selected backup by clicking Delete Backup.
5 Click OK to close the iTunes Preferences Window.
