However, choosing a reliable location to save the image files is also very important. 

The hard disk failure is one of the most common reason for lost backups you cannot avoid if save your backups to internal disk. While for NAS(network-attached storage), it's easily infected by virus or malware if it's always connected and many users have access to the shared folder. Then, which one is the safe storage to save image files?

You could consider backing up Windows 10 to external hard drive, like a USB drive. It's separated from computer and you can put it in a safe place. Also, you can easily connect it to computer via USB ports and then restore Windows 10 system image to new hard drive. In addition, it has strong endurance. It is not likely to be damaged unless you hit it with a hammer or something else.

★ Advanced way to backup Windows 10 to USB

Usually, to avoid your computer not working sometimes, except for system backup, you will be suggested to create a bootable USB or CD/DVD to boot your computer. But now you can use an easy way to create both of them simultaneously, it's using one key recovery software AOMEI OneKey Recovery.  And it allows you to access this software when your computer fails to boot via fast key, F11 or A, for example.

Create System Backup

Backup Windows 10 to USB using built-in tool

USB flash drive is a good file transfer tool as well as a great storage location for backup images. When it comes to backup Windows 10 to USB, many PC users would like to use Backup and Restore(Windows 7).

However, when you choose USB flash drive as the backup destination at the step of “Where do you want to save the backup?”, you will see a warning: “The drive is not a valid backup location”. This problem also happens when you use Backup and Restore in Windows 7/8. (In Windows 8, the tool is called Windows 7 File Recovery.)

Create a System Image

It is a default limitation that Windows users cannot save system drive image to USB flash drive. In earlier times, USB flash drive was created in small size. Therefore, it is hard and insecure to place a system backup image which is up to several GB in size on a flash drive, especially when schedule automatic backup is set.

Now you can get a USB drive with large capacity. To save a system image, the available storage space on USB should be at least 64GB. However, a 64GB USB is not suggested because the actual space is less than 64GB. Therefore, it is recommended to buy a 128GB USB. When you use a 128GB USB, you will not see this warning again.

Then, let's have a closer look how to create system image in Windows 10.

1. Search control panel  and the select it.  Then, choose View by Small icons or Large icons, find Backup and Restore (Windows 7) and open it.

2. In the main page of this software, click “Set up backup” to start the backup task.

Set up Backup

2. Select the USB drive as backup destination. If you cannot see it, click "Refresh" to reload. 

Save Backup on

Note: The option "Save on a network" is supported on Windows 10 Pro or higher version. To backup Windows 10 to network drive, it's suggested to use a third-party backup software, which does not have this limitation. 

3. Select “Let Windows choose” or "Let me choose", and click "Next". It all depends on what you want to backup, the recommended option will create a system image backup with the files on your desktop, user folder, and libraries included.  

Let Windows Choose

4. This software will automatically backup system every sundy at 7:00 PM by default, but you can change it by clicking the “Change schedule” option. Then, confirm the backup settings and click the “Save settings and run backup” button. 

Run Backup

5. Wait patiently untill the task completes. It all depends on the data your have and the speed of both hard drive. 

After the backup task ends, you will be asked to create a system repair disc, so you can restore your computer easily even when it's unbootable. It requires CD/DVD as backup drive. If you don't have this kind of storage device, you can still search "Recovery drive" in the search box and create Windows 10 recovery disk with USB drive. 

To restore system image from USB, you can follow the steps below

Step 1. Shutdown the computer completely. Then, open the back panel or host, take out the original disk and install the new hard drive back.

Step 2. Connect external hard drive containing Windows 10 backup image to your computer. Also, the system repair disc or recovery drive is required.

Step 3. Boot computer from CD/DVD or USB. 

Step 4. Select prefered settings and click Next. Then, choose Repair your computer > Troubleshoot > System Image Recovery > Windows 10 subsequently.


Step 5. Tick Use the latest available system image when you asked to select a system image backup, and then click Next.

Use the Latest Available  System Image

Step 6. Choose Format and repartition disks option, then click Next > Finish > Yes to start the restoration.


All in all, it's important to backup Windows 10 to USB, which can help you restore system image and get your computer back, even a new one. 

If you still don't have a system image for your computer, you need to create one immediately. You have two ways in total, either using third-party software or built-in tool. Both of them can help you, but you need to know that the built-in tool requires a USB drive at least 64GB, otherwise you will receive the error “The drive is not a valid backup location” during the process.

If you don't have enough budget or want a flexible software with more advanced feature, such as, schedule backup, full/incremental/differential backup, create bootable USB, universal restore etc, AOMEI Backupper will be a great choice. It is still a disk clone software, which can directly clone hard drive to SSD and boot your computer without restoration.
