iCloud is a service that allows a wireless way to create copies of data for all gadget owners with IOS operating system. And simply and automatically. This is done as follows.
1
The starting point of the backup process in ICloud will be the "Settings" section on your device. In it, scroll through the contents and find "icloud".
2
Next, in the ICloud itself, select the "Backup" or "Storage and Copy" option (if your iOS is not older than the 7th version).
3
By pressing the "Copy to ICloud" and "Create a backup". Under the last specified item will be displayed when the last backup has been made.
4
The synchronization process using the ICloud service captures everything except that there is already available in it (contacts, bookmarks, calendars, mail, photo thumbnails) or was made to your gadget not from the App Store, iTunes Store or IBooks Store.
5
Bacup using iCloud will be the most relevant in such cases: to recover data via Wi-Fi, with a rare device connection (iPhone, iPad, iPod) to a computer or when there is no computer at all, to copy automatic mode.
And we recall that icloud is a virtual storage for data copied from any iOS OS. That is, in order to subsequently access these data backups, you will need only the Internet.
