Meaning stuff like photos that would be stored in iCloud, or documents im Google Drive,  for example?

Figuring Proton Drive would suffice for now, pretty user-friendly, if she wants to take that step.

One of my medium-term projects is to set up a proper home server with something like StartOS and offer storage to family and best friends for whoever wants it. But I need to “put on my own oxygen mask” (and learn what the hell I’m doing) first 😉
