Why to create a system image on a USB drive?

A system image is a file which contains the system settings, programs, files as well as all the drivers required by Windows. With a system image at hand, you can restore system to a normal state if the system has damaged. You see the importance of creating a system image, and you may save it on a USB flash drive for following reasons:

  • You won’t lose the image file saved on an external USB drive due to system errors.

  • Compared to other external drives such as HDDs or SSDs, USB drives are more affordable and they can be connected to your computer directly.

The problem: the drive is not a valid backup location

There is a built-in tool in Windows to help users create system image, which is called Backup and Restore. However, some users find they can’t create a system image on a USB drive with Backup and Restore, only receiving a warning “The drive is not a valid backup location”.

The Drive Is Not a Valid Backup Location

Even if the USB drive is big enough to hold the system image and it is formatted as NTFS, the problem still exists. Actually, the error is caused by the limitation of Backup and Restore: it does not support USB flash drives or thumb drives as the backup location when creating a system image. Is there another way to create a system image on a USB flash drive? Surely there is.
