It's the same procedure the only thing is going to be that you have to use the DVD-R in order for you to record or to backup footage from the DVR. To start we're going to log into the DVR. The first thing you're going to do is plug in the Flash drive in this case because the Flash drive has to be formatted. You're going to plug it in to one of the USB ports on your DVR and go to the main menu, go to "Backup."
