What is the best way to back up a Mac to an external drive?

How can I back up my MacBook to an external hard drive? I prefer not to rely solely on iCloud.

The best way to back up your MacBook to an external hard drive is using Time Machine, Apple’s built-in backup tool. Here’s how:

  1. Connect your external hard drive to your MacBook via USB, USB-C, or Thunderbolt.
  2. Open System Settings (or System Preferences on older macOS) → go to GeneralTime Machine.
  3. Click Add Backup Disk, select your external drive, and click Set Up Disk.
  4. Time Machine will automatically back up your Mac hourly, daily, and weekly — keeping older backups as space allows.

:light_bulb: Pro Tips:

  • Use a drive with at least 2x your Mac’s storage for comfortable backups.
  • Enable “Back Up Automatically” so you never have to think about it.
  • You can also use Disk Utility to manually copy files, or tools like Carbon Copy Cloner or SuperDuper! for bootable backups.

Time Machine is the easiest and most reliable built-in option — no third-party software needed! :desktop_computer:
