If you don't want to lose your data on your Mac, a backup is a must. macOS comes with a simple solution: Time Machine. This backup feature automatically backs up all data on your Mac—from documents to system preferences. In this article, you'll learn how to set up Time Machine step by step, which drive you need, and how to ensure everything works properly.
Whether due to a hardware failure, accidental deletion, or a macOS issue, data loss happens faster than you think. Time Machine is the easiest way to protect yourself. Setup is straightforward and runs completely automatically. All you need is an external drive and a few minutes of your time, and Time Machine takes care of the rest. All the steps in this article are immediately actionable—no prior knowledge is required.
Connect backup drive
First, you'll need an external drive . Ideally, you'll want a hard drive or SSD with at least twice the storage capacity of your Mac. For example, if your Mac has 1 TB of storage, the backup drive should be at least 2 TB in size. Connect the drive to your Mac via USB, USB-C, or Thunderbolt. You can rename the drive, for example, "TimeMachine," so you can easily identify it later. macOS will usually automatically detect the drive and ask if you want to use it as a backup volume. If it doesn't, set it up manually—as described in the next step.
Activate Time Machine
- Open System Preferences on your Mac. On macOS Sequoia (and Ventura), you'll find Time Machine under "General" in the sidebar. On older versions, Time Machine is located directly in the System Preferences menu.
- Click “Add Backup Volume” or the plus sign (+), select your external drive, and confirm.
- Enable Time Machine by switching the switch to “On.”
- If necessary, macOS automatically formats the drive in APFS format, which has been standard for Time Machine since Big Sur.
Once setup is complete, the first full backup will begin. This may take some time depending on the amount of data. After that, all backups will run automatically in the background.
Adjust backup options
In the Time Machine settings, under "Options," you'll find the option to exclude folders and drives. If, for example, you have large video archives or external drives that you don't want to back up, you can add them here. This saves storage space and speeds up backups. You can also see here whether your backup drive is encrypted. If not, we recommend enabling encryption—this way, your data is protected even if the drive is lost.
Use automatic backups
Time Machine creates hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for older data. Older backups are automatically deleted when storage space becomes limited. As long as your backup drive is connected, you don't have to worry about anything. You can also use multiple drives and alternate them—Time Machine will automatically detect them and use them as an additional backup.
Test backup recovery
A working backup is only useful if you can access it in an emergency. Therefore, you should check whether you can perform a restore. Restart your Mac and hold down Command (⌘) + R during startup to enter Recovery Mode. Select "Restore from Time Machine Backup" and check that your backup drive is visible and readable. You don't have to complete the process—just make sure everything is recognized.
Time Machine: Your basis for reliable backups
A correctly configured Time Machine backup remains the most reliable data backup solution under macOS Sequoia and earlier versions. Setup is simple, requiring only a suitable drive and a little time. Afterward, your Mac will back up all important data automatically and regularly – without any intervention from you. If you also use a second backup strategy (e.g., cloud storage or NAS), you're doubly protected. But with Time Machine, you've already laid a solid foundation. Looking for new accessories?
