Uggh, feel bad for them.
I've tried for years to get friends and family to have their data sit in a single point in the house and use backup services. That would be a massive improvement.
Family won't listen, so I'm building minicomputers for them all that will handle it. Just have to configure their devices to store data there.
This started because one sibling asked about transferring photos from a phone, and I started documenting how to use Resilio and Syncthing.
