If you read my previous post about how to format an external hard drive, you know that I bought a 2TB Seagate Expansion external drive and managed to create two partitions on the disk — one for Mac backup purposes, and the other for personal use.
An internal hard drive is the most important part of a computer which is used to store data and support computer to work in a normal manner. If your iMac or MacBook does not recognize an internal hard drive and the drive is not showing up or mounting on Mac, not only will the system be unable to boot, but also the whole data stored on the computer will become inaccessible. The LaCie Porsche Design is one of the best external hard drives for Macs on sale today, and comes with both USB Type-C to Type-A and USB Type-C to Type-C connectors, making it a versatile way to expand the storage space of your Mac, regardless of what ports it has.
In this article, I’m going to show you how to backup your Mac data to an external drive. You should backup 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 the High Sierra update. You may also be interested in taking a look at the issues I encountered during that process just in case you also want to upgrade your Mac to the latest macOS.
Please note that the backup tool that I used is Time Machine, a built-in app provided by Apple. If you want to backup your Mac data without using Time Machine, there are also alternatives worth considering.
Where is Time Machine on Mac?
As I said, 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.
But the day I was feeding 25 teens, I needed a side I could make ahead and keep warm. I definitely feel that is best fresh, right off the stove. I wondered: Could I make my easy Mac-n-Cheese for a crowd, then put it in the crock pot to stay warm? Mac and cheese for 50. After all, I didn’t want to be a slave to the stove just as my guests were arriving.Obviously it worked marvelously, otherwise I wouldn’t be here telling you about it.
In the Preferences Pane, you’ll see the app located between “Date & Time” and “Accessibility”.
What does Time Machine Backup?
Time Machine is definitely the easiest way to backup Mac. In addition, 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 is bootable.
A Step-by-Step Guide to Backing up Mac to an External Hard Drive
Note: the screenshots below are taken based on macOS 10.12.5 Sierra. If your Mac has High Sierra or an older version, differences may exist, but the process should look similar to what’s displayed below.
Step 1: Connect your external hard drive.
First, use the USB cable (or USC-C cable if you’re on a 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.
It says I have to wait 5 hours
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.
One More Thing
Like any other hardware device, an external hard drive will fail sooner or later. It is advisable 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. I now use IDrive (read our full review here), and I really like it because the app is so easy to use, and it also allows me to back up my Facebook albums and photos automatically. Backblaze and Carbonite are also popular options in the market, though I have 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 recovery program like Prosoft Data Rescue and Stellar Mac Data Recovery, 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: Backup your Mac with Time Machine and create a second or third copy of those backups if you can.
How To Format External Hard Drive For Mac
You can use Time Machine, the built-in backup feature of your Mac, to automatically back up all of your files, including apps, music, photos, email, documents, and system files. When you have a backup, you can restore files from your backup if the original files are ever deleted from your Mac, or the hard disk (or SSD) in your Mac is erased or replaced.
Create a Time Machine backup
To create backups with Time Machine, all you need is an external storage device. After you connect the device and select it as your backup disk, Time Machine automatically makes hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. The oldest backups are deleted when your backup disk is full.
Connect an external storage device
Best Backup Drive For Mac
Connect one of the following external storage devices, sold separately. Learn more about backup disks that you can use with Time Machine.
- External drive connected to your Mac, such as a USB, Thunderbolt, or FireWire drive
- External drive connected to an AirPort Extreme Base Station (802.11ac model) or AirPort Time Capsule
- AirPort Time Capsule
- Mac shared as a Time Machine backup destination
- Network-attached storage (NAS) device that supports Time Machine over SMB

An encrypted backup is accessible only to users with the password. Learn more about keeping your backup disk secure.
If Time Machine doesn't ask to use your drive, follow these steps to add it manually:
Hard Drive For Macbook
- Open Time Machine preferences from the Time Machine menu in the menu bar. Or choose Apple () menu > System Preferences, then click Time Machine.
- Click Select Backup Disk (or Select Disk, or Add or Remove Backup Disk):
- Select your external drive from the list of available disks. Then select ”Encrypt backups” (recommended) and click Use Disk:
If the disk you selected isn't formatted as required by Time Machine, you're prompted to erase the disk first. Click Erase to proceed. This erases all information on the backup disk.
Enjoy the convenience of automatic backups
After you select a backup disk, Time Machine immediately begins making periodic backups—automatically and without further action by you. The first backup may take a long time, depending on how many files you have, but you can continue using your Mac while a backup is underway. Time Machine backs up only the files that changed since the previous backup, so future backups will be faster.
To start a backup manually, choose Back Up Now from the Time Machine menu in the menu bar. Use the same menu to check the status of a backup or skip a backup in progress.
