Your iPhone (and iPad) automatically back up to iCloud by default, but local iTunes backups are still useful. You should create an iTunes backup when you’re switching to a new iPhone or installing iOS beta software on your current phone.
您的iPhone(和iPad)默认情况下会自动备份到iCloud ,但是本地iTunes备份仍然有用。 当您切换到新iPhone或在当前手机上安装iOS Beta软件时,应该创建iTunes备份。
Local iTunes backups are more complete and faster to restore than iCloud backups. iCloud backups are still useful because they happen wirelessly so they’ll always be up-to-date, but iTunes backups are ideal for a full restore operation.
本地iTunes备份比iCloud备份更完整,还原更快。 iCloud备份仍然是有用的,因为它们以无线方式进行,因此它们始终是最新的,但是iTunes备份是完全还原操作的理想选择。
(How to Create an iTunes Backup)
Launch iTunes to get started. If you have a Windows PC, you’ll need to download iTunes from either the Microsoft Store or from Apple’s website. if you have a Mac, iTunes is already installed. We used the Microsoft Store version for this process, and it worked perfectly.

Connect your iPhone to your PC or Mac using the included Lightning-to-USB cable. This is the same cable you use to charge your phone. This same process works for iPads and iPod touches, too.

Before continuing, you should ensure your iPhone backups are encrypted. This makes sure they’re password-protected so someone will need the password you provide to access them and the data they contain. Encrypted backups can also contain account passwords, Apple Health information, and HomeKit data. Unencrypted backups won’t contain all the data.
在继续之前,您应确保iPhone备份已加密。 这可以确保它们受到密码保护,以便有人将需要您提供的密码来访问它们及其包含的数据。 加密的备份还可以包含帐户密码,Apple Health信息和HomeKit数据。 未加密的备份不会包含所有数据。
