Backup Your iOS Device
It is extremely important that you take a complete backup of your iOS device before upgrading to iOS 11. Things could go wrong during the upgrade process, so if this happens, you can safely restore your device and use the backup without losing any of your data. To backup your iOS device, you can use either iTunes or iCloud.
iTunes backup:
- Connect your iOS device to your computer and open iTunes.
- Click on the device icon in the top left corner of iTunes.
- Press the Backup Now button.
- Make sure to check the option to encrypt your backup. Doing so will save your private information like Health data.
iCloud Backup:
- Open the Settings app on your device.
- Tap on your name at the top of Settings, then tap on iCloud.
- Under the Apps Using iCloud section, scroll to the end of the list and press iCloud Backup.
- Toggle on iCloud Backup if you haven’t done so, then press the Backup Now button.
