Always have a backup before updating your operating system.
Whether you haven't updated to iOS 8.4 yet or you're considering joining iOS 9's public beta, it's always a good idea to make sure you've backed up your iPhone and iPad first. While you likely won't see any data loss after an upgrade, software glitches can and do happen; additionally, when testing a beta, certain things may not work like they used to. As such, it's worth it to protect your data before you embark upon an update.
iCloud backups should automatically happen at least once a day: They trigger when your iPhone or iPad is plugged in and on Wi-Fi. That said, here's how to make sure you have an up-to-the-minute backup solution.
How to make a backup of your iPhone or iPad using iCloud
- Launch the Settings app on your iPhone or iPad.
- Select iCloud.
- Tap Backup.
- Turn On iCloud backup under the Backup section if it isn't already — if it is, skip to step 5.
- Tap on Back Up Now.
- Wait for your backup to complete before updating.
How to make a backup of your iPhone or iPad using iTunes on your Mac
- Connect your iPhone or iPad to your computer via USB.
- Open iTunes and click on the device icon in the tab bar.
- In the Summary section, scroll to Backups.
- Change the Automatically Back Up section to This computer.

That's all there is to it! You can now upgrade your devices without fear. Keep in mind: If you want to back up to iCloud, you must first have an iCloud account and be signed in to it. If you don't and aren't sure how to make one, here's how to go about doing it.
