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 Driver nvidia mac os high sierra 2. , 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”! Box drive on mac os mojave.

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.
