Removing a Backup

computer. 
Remove a backup: 
In iTunes, open iTunes Preferences. 
 
Windows:  Choose Edit > Preferences. 
 
Mac:  Choose iTunes > Preferences. 
Click Syncing (iPhone does not need to be connected). 
Select the backup you want to remove and click Remove Backup. 
Confirm you wish to remove the selected backup by clicking Remove Backup.

Updating and Restoring iPhone Software 
You can use iTunes to update or reinstall iPhone software, restore default settings, and 
delete all data on iPhone.  
 
If you update, the iPhone software is updated but your downloaded applications,  
settings, and songs are not affected. 
  
If you restore, the latest version of iPhone software is reinstalled, default settings are 
restored, and data stored on iPhone is deleted, including downloaded applications, 
songs, videos, contacts, photos, calendar information, and any other data. In iTunes 
7.7, you can also restore from a backup without deleting data stored on iPhone. 
Note:  Deleted data is no longer accessible via the iPhone user interface, but is 
not permanently erased from your iPhone until it is overwritten by new data. For 
information about permanently erasing all content and settings, see “Resetting iPhone”
