iCloud is the Apple’s Storage system for their Mac devices and iOS devices like iPhone, iPad and many other devices where the company provides around 5 GB of free space for every iCloud account.
When a device is set to backup the to iCloud, then Apple automatically backup the data and settings stored locally on the particular device and it doesn’t create a backup of data already stored in an iCloud account through Mac or iOS apps as of iOS 8.1, that includes iCloud Photo Library, shared photo albums, My Photo Stream, documents, contacts, calendars, mail, bookmarks, and notes.
The backup of iCloud includes the purchase history from the iTunes or App Store, App data, home screen and app organization, imessages/SMS/ MMS text messages, device settings and visual voice mail on an iOS device.
The issue comes when the users have multiple devices, the old iCloud storage will be fill quickly as it comes up with 5 GB of memory and To delete an old iCloud backup from an iOS device you have to simply open the Settings app, and select iCloud, after that then select Storage. Users can easily find the line graphic at the bottom of the following screen representing the amount of the iCloud storage currently in use and then select the particular backup that you want to be deleted. Users with iCloud being used on multiple devices will have more than one.
After selecting the particular amount that you want to be deleted and you can simply choose the applications that you want the backup and by disabling the unnecessary applications from the backup you can easily free up the space within the iCloud Storage. Even you can notice the amount of available iCloud storage will increase in proportion to the size after deleting the that non-essential application.
To delete an iCloud backup from a Mac, open System Preferences and select iCloud. Then, select the Manage button on the bottom right of the window. Similar to the iOS device, users can able to see complete overview of how much iCloud Storage is currently being used. Next select the backup from menu and simply select the particular backup to be deleted.
Upon deleting iCloud backups can go a very long way, and can help ensure that the 5GB of free storage space is optimized.
