You’ve got a Western Digital Elements external hard drive. Or you’re thinking of getting one.
Because of all that stuff you have on your Mac. The music you love. Those photo’s of the kids with grandma. The spreadsheets you run your business with.
And it would be the end if you lost it all. Or if anything happened to your Mac.
And that’s where your WD Elements drive comes in.
It’s a reasonable priced bit of kit and now you want to set it up for a Time Machine backup.
Before You Use Your WD Elements For Time Machine
The first thing you need to do after hooking it up to your iMac, MacBook Pro or Air is to format it.
When delivered your WD Elements portable drive is in something called NTFS format.
Your Mac can read the documents on an NTFS drive but can’t use it for a Time Machine backup. Not without formatting first.
When you format WD elements for Time Machine be sure to format it as Mac OS Extended (Journaled) file system. And with a partition map as GUID.
If you’ve not done that yet go over to my document “Format WD Elements for Mac. How? In 7 Quick Steps” – to learn how.
Got your WD Elements portable formatted?
Great now we can start.

It looks a bit like a clock with an anti clockwise arrow on it.
When you click on it you’ll see a menu.

And away Time Machine will go creating your backup.
Your First WD Elements Time Machine Backup
Your first backup may take a little while in preparation and in backing up.
Depending on how much you have to backup this could all take a couple of hours or more.
Time Machine prepares by working out what needs backing up in this backup.
The first backup is of everything.
And this could take a while. But it all happens in the background and you can carry on using your Mac while the backup happens.
Or you could leave it overnight.
Just leave your Mac plugged into power and your WD Elements drive connected up.
And by the morning it’ll be done.
All following backups to your WD Elements drive are of the things that changed since your last backup. And so backups after that you’ll find are much quicker.
What Will Your WD Elements Portable Backup On Your Mac?
Everything. Your operating system, your programs, your music, photos, movies. Time Machine will backup anything that is on your Mac to your WD Elements drive.
Unless you go into Time Machine and say there are certain folders you want excluded.
And when you backup your iPhone, iPod or iPad to iTunes then they’ll be backed up by Time Machine too.
How Do I Know When My Mac’s WD Elements Time Machine Backup Is Finished?
Click on the Time Machine symbol at the top of your desktop.
I said checking this option would be useful for later.
It’ll tell you the progress of your backup. When it’s complete. And the date of the last backup you made.
You can also check on your desktop. The icon for your WD Elements drive will turn green when your backup is complete (depending on your Mac’s operation system version).
Remember To Eject Your WD Element Drive After Your Time Machine Backup
Just remember, as you would if you were using a USB stick that you need to eject your WD Elements drive from your Mac.
Do this when your Time Machine backup is finished. You don’t want to risk corrupting your backup…
What Are Your Options When You Use Your WD Elements With Time Machine?
Either you use your whole WD Elements portable drive for a Time Machine backup of your Mac.
Or if you have partitioned your larger 1TB, 2TB, 3TB or 4TB WD Elements drive into sections. You can use a Mac OS Extended (Journaled) file system partition for your Time Machine Backup.
To do that you simply choose the partition name you want to use. You do that on the Time Machine pop up window where you choose your backup target.
How Much Space Do I Need On My WD Elements For A Time Machine Backup?
Ideally twice the amount you’re backing up.
If you have 400GB of files, documents etc, you’re using on your Mac’s internal drive. Then you’re going to need at least 800GB of space to backup to. Twice the amount of space you’re using.
This is so that you can grow into your WD backup drive over time.
Formatting the Western Digital portable takes up space on the drive.
This means that your 1TB WD Elements is going to have less than 1TB of space for you to use.
But for your backup of your Mac’s 400GB of used space a 1TB WD Elements drive would be fine.
Can I Encrypt My Time Machine Backup On My WD Elements Drive?
Yes, you can encrypt your Time Machine backup with Time Machine.
On the screen where you pick your WD Elements backup drive. You’ll see a check box to encrypt. Once you select it Time Machine will encrypt your WD Elements back up.
And now you’ve learnt how to make a Time Machine backup with your WD Elements drive. With a backup you’ll have taken a copy of your files, keeping them safe.
Best practice says you should have two backup’s just in case one fails.
So do consider buying another Elements drive to backup to.
