To use Time Machine to make a backup of your Mac, you need one of these types of storage devices:
Back Up Your Drive Automatically With Time Machine. Backing up files manually is not the best solution, as you can never predict when your computer will break. It's better to back up automatically, so you don't have to think about it at all. Apple's built-in Time Machine is the best tool for backing up to an external drive.

Western Digital My Passport 4TB external hard drive is the newest generation of external hard disks and is available in capacities from 1 TB to up to 4 TB. It offers cloud storage and 256-AES encryption alongside WD's software for backups. The data transfer speeds won't disappoint you and the drive offers speed similar to what an SSD provides. If you want even more safeguards for your important files, there's also an option to back up data from the EX2 Ultra on to an external hard drive connected to one of its USB ports. Drive speed is measured in revolutions per minute (rpm), based on how fast the drive can spin. Most portable hard drives run at 5400 rpm. This reduced power draw helps preserve the battery life of the Mac you plug the drive into. Desktop external hard drives usually run at 7200 rpm to offer all the speed they can. The best external hard drives for Mac are not only useful for storing data but are an excellent way to transport files from one location to another. When you take into account price, ease of use, and portability, the Seagate Backup Plus Slim is the most reliable hard drive you can carry around with you at all times.
External drive connected to your Mac
Time Machine can back up to an external drive connected to a USB, Thunderbolt, or FireWire port on your Mac. If the disk isn't using the correct format, Time Machine will prompt you to erase it.
Network-attached storage (NAS) device that supports Time Machine over SMB
Many third-party NAS devices support Time Machine over SMB. For details, check the documentation for your NAS device.
Mac shared as a Time Machine backup destination
To use another Mac on your network as a Time Machine backup destination, complete these steps on the other Mac:
- Choose Apple menu > System Preferences, then click Sharing.
- From the list of services on the left, select File Sharing.
- From the Shared Folders list on the right, click the add button (+), then choose a folder to use for Time Machine backups.
- Control-click the folder that you added, then choose Advanced Options from the shortcuts menu that appears.
- From the Advanced Options dialog, select 'Share as a Time Machine backup destination.'
When setting up Time Machine on your other Mac computers, you should now be able to select the shared folder as a backup disk.
External drive connected to an AirPort Extreme Base Station (802.11ac) or AirPort Time Capsule
Time Machine can back up to an external USB drive connected to an AirPort Extreme Base Station (802.11ac model) or AirPort Time Capsule.
- Connect the drive directly to your Mac, then use Disk Utility to erase it.
- Connect the drive to a USB port on your AirPort base station, then turn it on.
- Open AirPort Utility, then select your base station and click Edit to view its settings.
- Click the Disks tab in the settings window.
- Select your backup disk from the list of partitions, then select 'Enable file sharing':
- If more than one user on your network will back up to this disk with Time Machine, you can use the Secure Shared Disks pop-up menu to make sure that they can view only their own backups, not yours. Choose 'With accounts' from the menu, then click the add button (+) to add users.
- Click Update to restart your base station and apply the settings.
AirPort Time Capsule
Time Machine can back up to the built-in hard disk of an AirPort Time Capsule on your network.

If you read my previous post about how to format an external drive for Mac, you know that I bought a 2TB Seagate Expansion external hard drive and managed to create two partitions on the disk — one for Mac backup purposes, and the other for personal use.
In this article, I'm going to show you how to back up your Mac data to an external drive. You should back up your Mac on a regular basis, especially if you're planning to perform macOS updates.
I did this several weeks ago while preparing my MacBook Pro for a system update. You may also be interested in taking a look at the macOS Catalina slow issues we encountered during that process just in case you also want to upgrade your Mac to the latest operating system.
Please note that the backup tool that I used is Time Machine, a built-in app provided by Apple. If you want to back up your Mac data without using Time Machine, there are also other third-party Mac backup software worth considering.
Where is Time Machine on Mac?
Time Machine is a built-in app within macOS ever since OS X 10.5. To find it, click on the Apple logo on the top left corner of your screen, then select System Preferences.
In the Preferences Pane, you'll see the app located between 'Date & Time' and 'Accessibility'.
What does Time Machine Backup?
Time Machine is the easiest way to back up Mac. And the app is created and recommended by Apple. Once you have a timely backup, it's incredibly easy to restore all or part of your data in case of accidental deletion or a hard drive crash.

So, what kind of data does Time Machine backup? Everything!
Photos, videos, documents, applications, system files, accounts, preferences, messages, you name it. They all can be backed up by Time Machine. You can then restore your data from a Time Machine snapshot. To do so, first open Finder, then Applications, and click on Time Machine to continue.
Be aware that the recovery process can be only be conducted when your Mac can start up normally.
A Step-by-Step Guide to Backing up Mac to an External Hard Drive
Note: the screenshots below are taken based on an older macOS. If your Mac is running Mojave or Catalina, they will look slightly different but the process should be similar.
Step 1: Connect your external hard drive.
First, use the USB cable (or USB-C cable if you're on the newest Mac model with Thunderbolt 3 ports) that comes with your external drive to connect that drive to your Mac.
Once the disk icon shows up on your desktop (if it doesn't, open Finder > Preferences > General, and here make sure you've checked 'External disks' to let them show on the desktop), move on to Step 2.
Step 2: Select the disk for backup.
Now open Time Machine (I tell you how above) and select the disk you want to use. I have partitioned my Seagate drive into two new volumes, 'Backup' and 'Personal Use', as you see from the screenshot. I chose 'Backup'.
Step 3: Confirm backup (optional).

If you have used another disk for backup before, Time Machine will ask you whether you want to stop backing up to the previous disk and use the new one instead. It's up to you. I selected 'Replace'.
Step 4: Wait until the process is complete.
Now Time Machine will start to backup all your data. The progress bar gives you an estimate of how much time is left before the backup is complete. I found it a bit inaccurate: Initially, it said 'About 5 hours remaining', but it only took two hours to finish. It's worth noting that the remaining time may vary from case to case depending on the write speed of your external hard drive.
After about an hour and a half, it says only 15 minutes remaining
Step 5: Eject your external drive and unplug it.

When the backup procedure is completed, don't rush to disconnect your device as this could cause potential disk problems. Instead, go back to the main desktop, locate the volume that your external hard drive represents, right-click and select Eject. Then, you can safely unplug the device and put it in a safe place.
Final Words
Like any other hardware device, an external hard drive will fail sooner or later. It's best to make a copy of the data on your external drive — as they say, a 'backup of your backups'!
One good option is to use cloud storage services like iDrive which I've been using and I really like the app because it's super easy to use, and it also allows me to download Facebook photos automatically. Backblaze and Carbonite are also popular options in the market, though I am yet to give them a try.

I hope you find this tutorial helpful. I can't emphasize enough the importance of data backup these days, especially when my mid-2012 MacBook hard drive died all of a sudden. I've also seen cases where my friend's computer and hard drive failed. You can imagine their desperation. Without a proper backup, it's really hard to restore data. Although you could try a third-party data recovery program, chances are they won't get all your lost data back.
Anyway, the main takeaway I want you to have from this article is this: back up your Mac with Time Machine or another app, and create a second or third copy of those backups if you can.
