You can copy and paste files to multiple locations in Windows 10. Ctrl+C and Ctrl+V are helpful keyboard shortcuts for copy and paste.
Question

Will this back up all files on my hard disk (including application files) such that I can fully restore my system if I need to (Mac Time Machine style)?

Yes, it's possible. If you are going to restore your computer, there are some options for backup. Just click on ''Restore/back up'' and choose back up the file, then follow instructions. It will create your backup. You can easily restore your computer and your data will remain saved.
Question

What if there is no "Add a drive" button?

Community Answer

Check very closely, the button is always there. But if it's not there, try restarting it or contacting the developers.

Warnings

Do not unplug your external drive or turn off the computer while backing up—you'll lose your backup progress and there's a high chance of corrupting the data on the external drive.

Backups generally take up a lot of space, especially if you don't delete old backups.
