Lesson video

Hello, my name's Mrs. Jones, and I'm really pleased you decided to join this lesson today.

In this lesson, we will look at making sure your data is safe and considering what you can do to keep data safe using backups.

Using digital devices, you store lots of different things, like photos.

And if anything happens to the device, you do not want to lose them.

Being able to recover data, accounts, and files is important.

In this lesson, you will look at why you should back up and how to do it.

You'll also consider the risks if you lose or damage a device.

So let's get started.

Welcome to today's lesson.

Today's lesson is called Backups and Keeping Data Safe from the unit From Unboxed to Recycle, the journey of a digital device.

And by the end of this lesson, you'll be able to explain how to keep data safe and how backups can support device recovery.

There are three keywords to today's lesson.

Backup.

backup is an extra copy of data stored in a different place.

Recovery.

Recovery is to retrieve and restore data that was lost or access to a system.

Cloud.

Cloud is a network of remote servers that can be accessed using the internet.

There are two sections to today's lesson.

The first is explain how accounts and backups support recovery.

And the second, identify risks linked to lost or damaged devices.

So let's start with explain how accounts and backups support recovery.

Data is defined as a letter, word or number, et cetera, that has been collected for a purpose, but is stored without context.

You can see three examples of data here, the letter C, the word purple, or the number 14.

That's data because we don't know what it means.

Without any context, we don't know what it is, and that is data.

Data is often stored on a computer or device.

Examples include documents, such as homework files, photos and videos, saved game data, login details, and passwords.

Losing data can be stressful and sometimes impossible to fix.

This means your work could be lost forever.

Keeping data safe is important.

We don't want to lose all our work forever, so it is really important we keep our data safe.

A backup is an extra copy of data stored in a different place.

If the original data is lost, damaged, or deleted, the backup can be used to recover the data.

Data can be lost for many reasons, for example, device damage.

A device may be dropped or damaged by water.

Hardware failure, a hard drive or a motherboard may fail.

Accidental loss, someone may accidentally delete a file.

Deliberate loss, virus or malware may delete or corrupt data.

Theft, a device could be stolen.

Let's have a quick check.

Which of the following are common causes of data loss?

Is it, A, device damage, B, accidental loss, or, C, app installation.

Pause the video to consider your answer, and then we'll check it.

Let's check your answer.

The answer was, A, device damage, and, B, accidental loss.

Well done if you got that correct.

Local backups are backups stored on a physical device you own, and this could be the memory stick, also called a USB, an external hard drive, or another device.

Cloud backups are backups stored on remote servers and accessed online.

Examples include iCloud, Google Drive, or OneDrive.

There are benefits and drawbacks of each type of backup.

Let's look at local backups.

So the benefits are it's fast to restore data and there's no internet access required.

However, the drawbacks are that you need to update manually, and that could be lost or damaged.

Let's look at cloud backups.

The benefits are that it's accessible from anywhere and automatic backups.

And the drawbacks are that there's limited free storage, which means that you might have to buy more storage to store your data and security out of your control.

Regular backups are important.

If a backup is old, it doesn't include the newest files or changes.

This means that if you need to restore your data, you might lose recent work, photos, or settings.

Accounts help keep your data and settings secure.

They allow services to remember you and your preferences.

Accounts support recovery by providing ways to prove your identity if you lose access.

You can see there some examples, facial recognition, might be a text message with a number, an email, or a fingerprint.

An account is a personal record that lets you access a service or a system.

It usually requires a username and a password.

Some accounts you may have or be familiar with include your school account, an email account, or maybe an online, a gaming account, and all of these would have required a username and a password to set up or access.

Common ways accounts support recovery include recovery email addresses, a link or code is sent to your email to restore access.

Security questions, answer preset questions to prove your identity.

Multi-factor authentication, a second check to allow access.

Jacob says, "Oh no, my smartphone got water damage and I've lost all my photos.

" Accounts link data and settings to the user, not just the device.

This makes it possible to access information on a new or replacement device because we wouldn't want to lose all our photos on our smartphone, so this is a really good thing that it's stored on the account, not on the device.

True or false?

It is always possible to recover lost data.

Pause the video to consider if that is true or false and why, and then we'll go through the answer.

Let's check your answer.

The answer was false, it is not always possible to recover lost data because it may have been permanently deleted, corrupted, or the storage device may be damaged.

Well done if you got that correct.

Let's do the activity and there are two parts.

The first, explain what a backup is and how it can prevent data loss.

And the second, explain how accounts support recovery.

Pause the video, complete the activity for both those parts, and then we'll go through the answer.

Let's have a look at the answer.

So the first part was explain what a backup is and how it can prevent data loss.

A backup is like a spare copy of your files.

If your computer breaks or you delete something by accident, you can use the backup to restore your files.

It stops you from losing important data.

The second part was explain how accounts support recovery.

Accounts support recovery by letting you prove it's really you to gain access.

They can send a code to your email or phone or ask a security question so you can get back into your account or access backups.

Accounts link data and settings to the user, not the device, so if you need to transfer to a new device, you can.

Well done for completing that activity.

Let's move on to the second part of today's lesson.

Identify risks linked to lost or damaged devices.

Sofia says, "Oh no, I have lost my tablet.

" Andeep says, "Did your tablet have a password or passcode, Sofia?

" It's a really good question if we've lost our tablet.

What are the risks of a lost or damaged device?

One is data loss.

If a device is lost or damaged, files, photos, or homework could be permanently lost if there is no backup.

So data that we store on a device could be gone, and there's no way of getting it back if we have not backed it up.

Unauthorized access.

If a device is lost, someone else may have access to your data, accounts, photos, and passwords.

This could lead to identity theft, impersonation, and privacy breaches.

We don't want to let anyone who doesn't have permission access, and that's unauthorized access.

And if they get access to our device, they can use it to access a lot more.

If they've got passwords, they can get into other accounts.

So we don't want to allow anyone onto anything that they shouldn't be.

Financial loss.

If a device is lost or damaged, it will cost you money to replace it.

You could lose money if your bank or payment details are saved on the device and someone uses them.

So we don't want to have to buy a new one, but we also don't want to allow somebody to have access to our personal bank details, because then they could use that to access our bank.

Stress and anxiety.

If a device is lost or damaged, it can cause significant stress and anxiety.

Sofia says, "My mum is going to be so disappointed that I have lost my tablet," and that's causing Sofia's stress and anxiety, she's worried about what her mum's going to say.

Let's do a quick check.

Match the risk to the example.

On the left, we have data loss, financial loss, and unauthorized access.

And on the right, we've got an online purchase is made that you did not approve, a school project is permanently deleted, a private message is read.

Look at the risk on the left and match it to the correct example and then we'll go through the answer.

So pause the video, have a go at that, and then we'll check it.

Let's check your answer.

So data loss is a school project is permanently deleted.

Financial loss, an online purchase is made that you did not approve.

And unauthorized access, a private message is read.

Well done if you got that correct.

You can take steps to reduce the risks and impact of lost or damaged devices.

Regular backups means you can restore your data if your device is lost or stolen.

Using strong passwords and multi-factor authentication protects your device from unauthorized access if your device is stolen.

Using tracking apps or features helps locate a lost or stolen device, and remotely wipe all data if necessary.

Physical security, don't leave devices unattended.

Store them safely, and if appropriate, label your device so it can be returned to you.

Let's do a quick check.

True or false, losing a device only risks the device itself.

Pause the video to consider if that is true or false and why, and then we'll check your answer.

Let's check your answer.

The answer was false, losing a device also puts personal data, accounts, and privacy at risk.

Well done if you got that correct.

Let's do the activity, and there are two parts.

The first, identify two risks linked to lost or damaged devices.

And the second, for each risk, suggest steps that could be taken to reduce the risk.

Pause the video, have a go at both parts of this activity, and then we'll go through the answer.

Let's have a look at the answer.

So the first part, two risks could be losing data and unauthorized access.

The second part, losing data is a risk, for example, I could lose my homework if my laptop is stolen or damaged.

I would then get into trouble for not handing in my work.

This risk could be reduced by backing up my homework on the cloud or an external hard drive.

Unauthorized access is another risk.

For example, someone could access my gaming account and spend my game credits.

This risk could be reduced by using strong passwords and multi-factor authentication so only I can access my accounts.

Well done for completing the activity.

In summary, a backup is a copy of important data stored somewhere safe.

This could be online or on another device.

Backups protect information if something goes wrong.

Regular backups ensure no recent data is lost.

Accounts link data and settings to the user, not just the device.

This makes it possible to access information on a new or replacement device.

If a device is lost, personal data may be accessed by others.

Well done for completing this lesson, Backups and Keeping Data Safe.
