System crashes or hardware damage often happen unexpectedly. Therefore, it's essential to backup the computer in advance. So, how to backup our computer to an external hard drive to avoid data loss? In the following passage, I'll introduce the importance of backing up and two ways to backup the entire PC to an external hard drive.

Part 1: Why do We Need to Backup Entire PC to External Hard Drive?

We need to backup the entire PC to protect our data. By backing up, we will get a copy of essential files. And when the system can't operate normally, we can recover the original system to ensure work continuity. So backup can avoid data loss caused by the following reasons:

  • System crash
  • Computer virus infection
  • Hard drive failure
  • Data deletion
  • System formatting
  • Manufactured mistakes

For data protection, there are various backup storage devices. For example, you can backup the system to another hard drive or the cloud. But using an external hard drive for backup is one of the most efficient ways because of the following features:

  • Economical: the price is usually affordable.
  • Convenient: it's easy to carry, and you can find important information anytime.
  • Storage: it's compatible with all types of files and can save space for the computer.  

As a result, it is vital to backup your computer to an external hard drive. So how to backup the computer to an external hard drive? Next, I will introduce backup methods to backup Windows 10 and you can choose the preferred one.

Part 2: How to Backup Entire PC to External Hard Drive?

After you know the importance of backing up and you also know where you want to save the backup. Then, it's time to find a proper method to operate the backup. Here, I will introduce two ways of backing up.

With Windows Built-in Backup Tool - Backup and Restore

As the most widely used operating system in the world, Windows has a built-in tool. And you can create a system image to restore the whole computer. The backup method that comes with the system is free and you can find the detailed steps on the internet.

Windows Backup and Restore VS EaseUS Todo Backup, Which is Better to Backup PC?

Here, I will compare the two ways of backing up the computer:

Comparison Windows Built-in Backup Tool EaseUS Todo Backup
Efficiency Slow, and longer backup time Quick, and shorter backup time
Security Inability to protect data from viruses Encrypt the backup images
Compatibility Unable to connect some drives Support all kinds of disks
Backup types Full backup and partial backup Full, incremental, or differential backups
Backup plan Both can set the backup plan and it will do it automatically.

And next, I'll introduce how to backup the entire PC to an external disk with these two methods step by step.Now, it's clear that Windows Backup and Restore does help to backup system and partial content on your PC. However, it's not an efficient solution as it takes a longer time to create a backup. Also, you can't backup the computer to an external hard drive with Windows Backup and Restore. Fortunately, you can trust EaseUS Todo Backup. EaseUS Todo Backup is an excellent choice for creating a comprehensive backup.

Part 4: Backup Entire PC to External Disk with Backup and Restore

Backup and Restore allow you to backup a single file or the whole PC. Backup the entire PC means you can save all your operating systems, programs, and files to another device.

If you want to use the Windows method, you can follow the steps to backup your PC: 

Step 1: Connect the external drive to the computer and ensure it can be accessed properly. And then, you can begin to backup the whole PC to the external disk.

Step 2: Find the "Control Panel" on your computer, and click "System and Security" to backup the computer.


Step 3: Select "Backup and Restore(Windows 7)".


Step 4: On the left side, choose "Create a system image" to save all the computer systems to an external hard drive.


Step 5: In the pop-up window, choose where to save the backup and select the attached external hard drive in the "On a hard disk" list.


Step 6: Choose which drives to include in the backup.


 Step 7: Next, confirm backup settings: the backup locations and what will be backed up. And then, select "Start backup" to begin the backup process.



1. Because the Windows Built-in Backup Tool usually takes a long time to proceed with the backup, it's better to backup the system image in your spare time.
2. A partial backup of your system can also be made with the Windows built-in tool: find "File history" on the "System and Security" window, and it will save the necessary files.


We need to be aware of the importance of backup. And backup computer ahead of time to an external hard drive is one of the most efficient ways to protect your data. It is essential to perform regular backups. So knowing a simple and professional backup software can help us save time and money. Besides, EaseUS Todo Backup can also make a rapid system image recovery after backing up. If you want to know more about software, you can have a try.
