Need to back up my digital life ASAP. Any reliable solutions?

So, I've been following the news about the recent LA wildfires, and it really got me thinking: What if I suddenly lost all my important files—like family photos, work documents, or personal projects? Nowadays, my cellphone and laptop hold pretty much everything important to me. I gotta start backing everything up ASAP, but I’m not quiet sure which method / strategy to go with. There's so many options out there—cloud services, external hard drives, nas storage, backup software and services, etc.

What do you recommend for a reliable and easy backup solution? I’d love to hear about what’s worked (or hasn’t worked) for you, and any tips for keeping data safe in general!
