iCloud Storage - How to manage?

This is a how to guide to manage your iCloud storage. In my situation, I am using a number iPhone's, iPad, and iPod for our family iCloud's account, and I have 20Gb of paid storage ... still not enough. We are using the iCloud storage for sharing pictures within our family. We don't need to backup the email because it is already in the Cloud using Google Apps (see reference below).

Here's what to check using your iPhone, similar approach for iPad and iPod.

• In your iPhone, tap "Settings", scroll down to see the iCloud setting.
• Tap "iCloud", here you can turn OFF the following if you don't need them. I turn off Mail, because my email is already in the cloud. I keep my Contacts ON for now. I turn off my Calendars (this is part of my email cloud). I turn off my Reminders, Safari, Notes, Passbook (I will get back to this setting if I will use this in the future). I turn ON Photo Stream for family to shares our pictures. I turn off "Documents and Data". And I turn ON Find My iPhone for tracking the family's location.
• Let's continue, and check other backup settings. Tap the Storage & Backup.
• In iCloud Storage & Backup, tap Manage Storage.
• In Storage & Backup Manage Storage, Backups will provide the total of storage in gigabyte. I have close to 20Gb, so I tap my iPhone to see more details of usage. In here, you will see backup size for Camera Roll, Twitter, Blogger, Wordpress, Google+, and games I've used in the past. Here you can turn OFF the apps that you don't need backup. When you turn OFF, it will be deleted as well. Don't worry you can re-download the apps from your iTunes account. I turn off and delete Angry Bird, I definitely don't need it my iPhone.
• That's all.

My iPhone Camera Roll took 80% of storage space because of pictures and videos in my iPhone. That's ok, my family love to take pictures from family gathering, birthday, vacation, holiday, and even wacky pictures for fun.

I hope this help!
