Here is a GREAT way to do this. It requires a USB thumb drive and a USB external hard drive as well as some free software, Veeam, and maybe Rufus. ( and in the end, you can have scheduled bare metal backup, daily if you wish).
Download Veeam Version 6.3.2 zip file HERE
Download the latest version from Veeam HERE you will need to sign in
Download Veeam Endpoint Backup free. This is Enterprise/business software with a free product so you can see how it works before you spend thousands of dollars per month on the BIG toys. It is a trustworthy company, remove the tick for marketing material. Install Veeam and then run. When you run it the first time, it will prompt you to create a bootable disk/iso. I select iso and save it to the downloads folder.
Download rufus and install.
Plug in the USB stick and use rufus to make a bootable disk from the iso.
Plug in the USB external disk.
Open Veeam and create a backup schedule. Complete one backup of the whole volume/disk to the external USB hard drive.
