data synchronization – Store matching files in icloud AND on Mac and Macbook

I signed up for iCloud storage for added security (in case my local computers crash or are stolen), but am finding out iCloud is trying to only keep certain frequently used files also on my Mac (running 10.13.6) and Macbook Pro (running 11.1).
Is there a way to force iCloud to keep all files at all times current in both iCloud and on my local machines (that have plenty of available storage space), so then when/if I lose internet, power goes out, or iCloud gets hacked and everything gets deleted/corrupted, I will always have safe and complete versions on my computers? Thanks!
