If you want to perform a "bare metal" backup of a Microsoft Windows 10 system
to an external USB
drive without a third-party application, you can use the
Backup and Restore utility that is provided by Microsoft with the
operating system. You can run the program from a command-line interface
opening a command prompt window with
administrator privileges and issuing the command
backup -backupTarget:x -allcritical -quiet where
is the drive letter for the drive where you wish to store the backup.
When you add the
-quiet option, the backup will be run with no
prompts for the user. The
--allcritical option "creates a backup
that includes all critical volumes (critical volumes contain the operating
system files and components)."
