The recovery media is only used to boot into the Macrium Interface. The disk image should be stored onto a USB external drive or if you wish onto another USB flash drive but I don't recommend you backup images to a USB flash drive. This disk image would include all partitions on the disk including any factory restore partition.
Lets say you added numerous programs to the computer and had some major updates too. The disk image you create would restore your computer to the point of the last disk image you created including all programs and updates so if the drive failed or the computer no longer booted your could restore your computer and be back up in minutes vs hours of reinstalling the OS, programs, and then updates.
With a Windows 10 Recovery Drive, you would just be creating a bootable USB flash drive that would allow you to have the Advanced Recovery Options if you could not get to them normally allowing you to do a system restore and access to a command prompt or the factory reset on the hard drive.
You can create a system image in Windows 10 similar to Macrium using File History but Macrium has a lot of advantages over Window's own imaging program.
