iTunes backup is the least thing that Apple users are unfamiliar with. Most users even backup iDevices on a regularly basis. This post will cover everything you need to know about iTunes backup including how to backup iPhone, iPad and iPod, as well as how to restore data from iTunes backup.
iTunes can back up most data on your iPhone, iPad, or iPod touch, which could help you restore data from iOS devices once you deleted or lost data from iDevices.
Backed-up information includes purchased music, TV shows, apps, and books; photos and video in the Camera Roll; device settings (for example, Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts); app data; Messages (iMessage, SMS, and MMS), ringtones, and more.
When you lost data from iPhone, iPad or iPod, you can restore lost data from iTunes backup. Your data on iOS devices may get lost for various reasons, just name a few:
Some people prefer to set iTunes to back up iPhone, iPad and iPod automatically when they connect iOS devices to PC or Mac. For those who haven't chosen auto backup, find the Backup option when iTunes is launched. Then in Manually Back Up and Restore, choose Back Up Now.
To backup apps, use the Transfer Purchases option found when you right click your device on iTunes.
Editor's Note: Restoring iTunes backup does help you get back lost data on iPhone, iPad and iPod. However, after the restore data on your iDevices will be exactly as that of the day you did the backup. If the data is added after the backup, you have no way to restore them from iTunes backup. In such cases, you could use iPhone Data Recovery to recover contacts, SMS, call history, photos, etc. directly from iPhone, iPad and iPod or from iTunes backup.
Restore data from iTunes backup is easy:
Since restoring your device from a backup does not restore apps, you can drag the apps transferred to iTunes back to your device.
