User case: mirror Windows 10 image backup to USB

My computer is running Windows 10, and the OS takes up 67 GB of disk space. Recently, I bought a 128 GB USB flash drive and I would like to mirror a Windows 10 image backup. My question is how to mirror the system image to this USB? I hope someone can help me.

This user want to "mirror a Windows 10 image backup" which is basically creating a system backup that includes everything required by Windows to run (operating system files, personal files, installed programs, etc).

For space saving and disaster recovery reasons, such backups are usually stored somewhere other than the local disk, such as on an external hard drive, USB flash, or network share. 

Main benefits of mirror image backup

Usually, people may want to create a system image backup in Windows for the following reasons:

  • Protect your data: Sometimes there might be severe system errors or virus that affect your important data. To safeguard data security, it's necessary to mirror an image of your computer.

  • Avoid reinstalling the system: If you need to replace hard drive or computer, yet don't want to reinstall system from scratch or re-download all the programs & files you've collected for so long, then you may mirror an image of your system and directly restore it onto the new device. Also, if you have a poor use experience after a Windows 10 update, you can simply revert to an earlier state easily, like return Windows 11 to Windows 10.
