I'd rather lose my tax and financial records than lose our family photos!
Accordingly, I back them up locally to a Synology file server here, then back that up automatically to two different off-site locations, one cloud and one physical (cloud is Amazon S3, which is a paid service and critical to Amazon's financials; the physical location is mine).
IMO, if the backups aren't fully automated, they eventually (and usually quite soon) cease to exist in an up-to-date form.
That aside, many laptops are now equipped with USB3 ports, which are capable of carrying multiple monitors' worth of pixels, charging power, and peripheral connectivity, so the docking station could very well be "plug this cable in" instead of a custom to each model $300 piece of waste. I don't think I'd use that for gaming, but most any other use that needs dual monitors, that should work quite well.
