User Case

“Hello! What is the easiest/fastest way to backup my Windows? I am using Windows 11 and seriously consider to start making a full backup to external hard drive in case of a serious hardware or software problem. So, is there a perfect way to backup system safely and easily? Thank you!”

For users who need to backup Windows 11 to external hard drive, this article will introduce you two simple, quick and safe ways. One is built-in tool “Backup and Restore” and the other is third-party software “AOMEI Backupper”.

Reasons for Backing Up Windows 11 to External Hard Drive

Backing up Windows 11 means making an exact copy of Windows 11 operating system files, applications, data, etc. so that users can recover to the previous system state in time if they encounter system crash, hard drive failure, virus, human error etc.

Besides, backing up your Windows 11 to an external hard drive is more secure than an internal disk for it reduces the risk of backup image corruption.

How to Backup Windows 11 to External Hard Drive?

In this part, I will show you 2 methods to backup Windows 11 to external hard drive. You can choose the one that suits you best.

Method 1: Backup Windows 11 to External Hard Drive using Built-in Tool

The method most people think of first in their mind, is to use the built-in tool that comes with Windows called “Backup and Restore”. The built-in software can backup Windows 11 OS to external hard drive by creating a system image. If you have a problem with your system, you can restore the system backup and then use it again without installing anything. The following are specific steps.

Step 1. Go to  Control Panel > System and Security > Backup and Restore (Windows 7).

 Step 2. Click Create a System Image option.

Step 4. Confirm your backup settings, and click Start Backup.

After that, you’ll be prompted to make a system repair disc. It needs a CD/DVD as storage device. If you don’t have a CD/DVD, you can make a bootable USB using built-in Recovery Drive tool or a third-party bootable media creator. Since it can help you start your computer if your Windows OS encountered any boot problem.

Method 2: Backup Windows 11 to External Hard Drive using AOMEI Backupper

When you use the built-in tool to backup system to external hard drive, you need to pay attention to the following points:

  • It doesn’t support differential backup.
  • If you created a system image on a large disk, you can’t restore it to a smaller SSD.
  • It only supports to restore the whole system, so you cannot restore a single file from the image.

Therefore, if you are looking for a more secure and reliable software to backup and restore your system, you can choose AOMEI Backupper Standard. It has a powerful system backup function as well as features of partition backup, file backup,  and disk backup. Besides, it provides some additional functions.

  • You can write comments to your backups and set up email notifications.
  • It offers different backup modes (intelligent sector backup or exact backup) and different compression levels (high/normal/low).
  • You can backup your files with fixed intervals (daily/weekly/monthly) and choose a way to perform  the scheduled backup, both full backup and incremental backup are available.
  • It supports various storage devices, such as USB, HDD, SSD, etc.
  • It has great compatibility in the operating system (Windows 7, 8, 8.1, 10, 11, XP, Vista, etc.)

In addition, It offers various backup schemes (professional version), which can greatly meet your multiple needs and help you save time and disk space by deleting old backups.
