Ohh, this looks pretty cool. I was actually considering building such a thing myself, but I hadn't gotten around to it.

I tlooks quite a bit more expensive than google photos, but I could probably live with that. What I do want to know is where you are storing the photos, and what precautions you have taken to ensure data is not lost (assuming I still have access to my encryption key)

We're currently using B2[1] in Amsterdam for hot-storage, and Scaleway[2] in Paris for cold-storage.

Replication to cold-storage is triggered as soon as a file is uploaded, and it will retry until the file hashes match across both providers.

Our production database is backed up once a day, and has a secondary node to which data is replicated synchronously.
