In my case I work with a family member in another city. We connect via VPN (tailscale works well too if you prefer that) and push the data we want to backup. Something like nextcloud could be used too, although a regular file explorer works just fine once you’re connected.
Now mind you it’s mostly family photos, so not petabytes of data.

It’s also opt in. Although I’d be surprised if anyone commenting here is actually using google photos in the first place.
