iCloud backup
iCloud is a cloud storage and cloud computing service by Apple launched in October 2011.
The service allows users to keep data such as calendars, contacts, reminders, photos, docu-
ments, bookmarks, applications, notes, and more in sync across multiple compatible
devices (iOS devices running with iOS 5 or later, computers with Mac OS X 10.7.2 or later,
and Microsoft Windows) using a centralized iCloud account. The service also allows users
to wirelessly and automatically back up their iOS devices to iCloud. iCloud also provides
other services such as Find My iPhone —to track a lost phone and wipe it remotely, Find
My Friends —to share location with friends and notify the user when a device arrives at a
certain location, and so on.
Signing up with iCloud is free and simple to do with an Apple ID. When you sign up for
iCloud, Apple grants you access to 5 GB of free remote storage. If you need more storage,
you can purchase the upgrade plan. To keep your data secure, Apple enforces users to
choose a strong password when creating an Apple ID to use with iCloud. The password
must have a minimum of eight characters, a number, an uppercase letter, and a lowercase
letter.
iOS devices running on iOS 5 and later allow users to back up the device settings and data
to iCloud. Data backed up includes photos, videos, documents, application data, device set-
tings, messages, contacts, calendar, e-mail, keychain, and so on. You can turn on iCloud
backup on your device by navigating to Settings | iCloud | Storage & Backup , as shown
in the following screenshot. iCloud can automatically back up your data when your phone
is plugged in, locked, and connected to Wi-Fi. This is to say, iCloud backups represent a
fresh and near real-time copy of information stored on the device.
