The easiest way to back up your data is using your iCloud account. Using iCloud to back up your iPhone is an automatic solution that will let you restore your content from almost anywhere using WiFi.
To set up iCloud backups: Tap Settings > iCloud > Backup. If you’re using iOS 7 or earlier, tap Settings > iCloud > Storage & Backup. Tap “iCloud Backup” to turn it on. Tap “Back Up Now” to secure your data before clearing it off your iPhone.
After you turn on iCloud Backup, iCloud will continue to back up your content automatically. You can return to this screen to see when the last back up happened.
If you are using iCloud to back up your phone, be sure to sign out of iCloud before shipping the phone to Orchard. You can find instructions for doing so here.
If you don’t have an iCloud account, you can use iTunes to put your backups on a computer.
To use iTunes to backup your data, first make sure your computer has the latest version of iTunes. Then, connect your iPhone to your computer with your charging cable. In your iTunes, go to File > Devices > Back up.
To check that the backup finished successfully, open iTunes Preferences and select the Devices tab. You’ll see the name of the device along with the date and time iTunes created the backup.
