Plenty of Mac owners believe iCloud is their backup, then discover it is not quite that. Time Machine and iCloud solve different problems, and understanding the difference could save you from losing something you care about.
What Time Machine does
Apple says Time Machine backs up the photos, music, movies and documents stored on your Mac. Once you set it up, it backs up regularly without further effort. It is built to restore your Mac or individual files from an earlier point in time. See our full guide to Time Machine for setup.
What iCloud does
Apple describes iCloud as a way to sync and access data across all your devices signed in with the same Apple Account. It keeps photos, videos, contacts, calendars, notes, passwords and more available everywhere. You can also use iCloud Drive to store other files, including your Desktop and Documents folders.
The key difference
Time Machine keeps a copy of your Mac. iCloud keeps your data available and in sync. Syncing is not the same as an independent backup: if you delete a file in a synced folder, that change goes to your other devices too. Apple itself lists iCloud as a way to sync and store data and Time Machine as a backup method on its “Ways to back up or protect your files” page, and says you can archive or make copies of what is stored in iCloud for an extra copy.
| Time Machine | iCloud | |
|---|---|---|
| Main purpose | Back up your Mac | Sync and store across devices |
| Needs extra hardware | Yes, a backup drive | No |
| Uses iCloud storage | No | Yes, counts against your plan |
| Access from other devices | No | Yes |
| Covers the whole Mac | Yes, photos, music, movies and documents on the Mac | Only what you choose to sync |
What iCloud storage means for your wallet
Apple says storing files in iCloud uses space in your iCloud storage plan. If you reach the limit you can buy more or free up space. We are not listing prices here, because Apple changes them by region.
Our take
For most people the answer is both. Use iCloud for convenience and access on your phone. Use Time Machine, or another backup, so you have a copy that does not depend on a single account or on sync behaving. This is our opinion, not Apple’s rule, but it is the setup that protects against the most kinds of loss.
Apple’s other options
Apple also lists copying files by hand to a USB drive or external storage, and third-party backup utilities, noting that it does not endorse those products.
