How to Backup iPhone 6 to iCloud
After you set this up, your iPhone will automatically back up to iCloud whenever your phone is locked, plugged into a power source, and connected to Wi-Fi. To set up iCloud backup on iPhone 6, 6 Plus, 6S, and 6S Plus, follow these steps:
How to Backup iPhone 6 to iTunes
If you already manage the data on your iPhone by syncing with iTunes, this is a good option. You must connect your iPhone to the computer running iTunes and start the process yourself. To backup iPhone 6, 6 Plus, 6S, or 6S Plus to iTunes, follow these steps:
How to Backup iPhone 6 to Your Computer
While iTunes is probably the easiest option to backup iPhone 6 to a computer, it’s not the only choice. There are a number of third-party programs that both offer backup and features that iTunes doesn’t have. These can include the ability to browse hidden files on the iPhone, recover photos, voicemails, and text messages that seem to be deleted, and more. These programs are generally paid and may not be as comprehensive or reliable as iTunes. We don’t recommend using these programs as your only backup tool. However, the features they offer that iTunes doesn’t can be just what you need in some circumstances.
Why You Should Back Up to Both iCloud and Computer
We recommend that you use both methods. The best practice you can follow when backing up your data is to have two copies of it: one close at hand if you need it right away and one offsite from you that you can get if something happens to the nearby copy. For instance, having a backup in your house isn’t very useful if you need the backup when you’re on vacation or if you house burns down with the backup inside. It’s a little more work, and you may never need two backups, but if you ever do, you’ll back glad you spent the extra time to backup twice.
