What are the requirements? Large capacity, redundancy, reasonable access speed, always on but maintenance downtime of even a few hours a year tolerable?<p>Easy but your data isn't yours: sync your data to GDrive or Apple or whatever, and sync a NAS to that.<p>A little harder but still doable: get a Hetzner and set that up as your storage, set up your own access, sync to local NAS. A Hetz is also really useful for running a load of other services, so for 50 bucks or so it seems pretty reasonable.<p>You could just buy a huge disk and run a server in your house, but it gets annoying in various ways. Kids unplug the power, it creates heat, maybe noise, multiple disks end up needing management, that kind of thing.
