iCloud backup toggle on the iPhone
You can also initiate an iCloud backup from a computer by connecting the device to
iTunes and choosing the iCloud option. iCloud backups are incremental, that is, once the
initial iCloud backup is completed, all the subsequent backups only copy the files that are
changed on the device. iCloud secures your data by encrypting it when it is transmitted
over the Internet, storing it in an encrypted format on the server, and using secure tokens
for authentication.
Tip
iCloud does not encrypt
Email
and
Notes
stored on the server to be consistent with stand-
ard industry practices.
Apple's built-in apps (for example,
Email
and
Contacts
) use a secure token to access
iCloud services. Use of secure tokens for authentication eliminates the need to store the
iCloud password on devices and computers.
