Part 3:  iPhone/iTunes Backup, Update, Sync and Restore Best Practices

If you back up your iPhone, iPad, or iPod touch, you'll have a copy of your information to use in case your device is ever replaced, lost, or damaged. So we always encourage users to have solid iPhone backup using both iCloud and your computer. To help you avoid and survive from severe iOS data disasters, we suggested you consider the following iPhone/iTunes Backup, Update, Sync and Restore best practices.

General Tips for iPhone Backups:

  • Use Encrypted iPhone Backup with iTunes: When creating encrypted iPhone backup, write down your password and store it somewhere safe, because there's no way to recover your iTunes backups without this password.
  • Use Backup To Transfer Data To New iPhone: You can copy and save the information on your iPhone by backing it up to either iCloud or to your computer. If you replace your device, you can use its backup to transfer your information to a new device.
  • iPhone Backup Includes Almost Everything: Syncing your iPhone with your computer isn't the same as making a backup. A backup from a computer or iCloud includes nearly all of your device's data and settings.
  • Keep iPhone Backup Safe and Intact: Don't edit, relocate, rename, or extract content from your backup files, because these actions might ruin these backup files.
