You might want to open a Command Prompt using the "Run as Administrator" option and use the ROBOCOPY command. See: http://ss64.com/nt/robocopy.html
Someone else just happened to ask about copying over a full folder structure from one folder to another, but selecting only files of a certain type. In your case you want to do the same but for all files.
The syntax you would use is dirt simple: ROBOCOPY Source_Folder Destination_Folder /S /E
This presumes you want to copy every blessed file and folder that resides under the Source_Folder to the Destination_Folder including empty folders, too.
For Example: ROBOCOPY C:\Users\User1 D:\User1Bkup /S /E
But, after all that, is there some reason you're not using the absolutely marvelous File History feature that's built in to Win10? It makes life much easier in this regard and you can add folders that aren't included by default or exclude folders you don't want that are included by default.
