When you're trying to keep your data safe on an Apple device, two of the most common options are Time Machine and iCloud backups. But they’re not the same—and knowing the difference can help you choose what’s right for you.

What Each Backup Covers

iCloud backup is mainly for iOS devices like iPhones and iPads. When you turn it on, it automatically backs up things like your home screen layout, app data, messages, photos (if iCloud Photos is on), settings, and Health data. It doesn’t include things like music, videos, or apps you can re-download—they get restored automatically when needed.

Time Machine, on the other hand, works with Macs and focuses on your entire system. It backs up your files, apps, system settings, and even your desktop layout. You need an external drive or a network storage device connected to your Mac for it to work.

• iCloud: Great for mobile devices and smaller, key data
• Time Machine: Full system backup for Macs

How They Work Day-to-Day

One big difference is how hands-off each one is. iCloud backup runs automatically when your device is plugged in, locked, and connected to Wi-Fi. That means once you set it up, you don’t really have to think about it again—unless you run out of space.

Time Machine also runs automatically, but only when your backup drive is connected. By default, it makes hourly backups (for local snapshots on laptops) and daily backups when the drive is available. If you travel often with your laptop, you might forget to plug in the drive, which means gaps in your backup history.

• Set it and mostly forget it with iCloud
• Time Machine needs a physical connection to the backup drive

Storage and Space Management

Storage is another area where these backups differ. iCloud gives you 5GB of free space total, shared across all your devices. Most people end up paying for more storage because photos and app data add up quickly.

Time Machine uses as much space as you give it. If you have a 1TB drive, it’ll use that to store multiple versions of files over time. You can even access old versions or deleted files through Time Machine’s interface.

• iCloud storage fills up fast—especially with photos
• Time Machine uses local storage and keeps older file versions

When to Use One vs. the Other

If you just want your iPhone to be recoverable without too much effort, iCloud backup is the way to go. It’s simple and automatic. But if you’re setting up a new Mac or recovering from a bigger issue, Time Machine gives you a full snapshot of your system.

Many people actually use both. For example, someone might back their MacBook with Time Machine and their iPhone with iCloud. Some even enable iCloud Drive on the Mac to sync certain documents between devices.

• Use iCloud for mobile device recovery and syncing
• Use Time Machine for full Mac system backups

So depending on your setup and what kind of data matters most, you might find yourself using one or both. The key is understanding what each covers and how they fit into your overall backup plan.基本上就這些.
