I went down an almost identical path/plan, but then stopped due to corruption concerns with doing the VPS / home sync the way that I wanted without a NAS in the middle managing the thing. It’s still possible, but it explodes the complexity.

One of the big things I wanted to accomplish was low cost and easy to integrate / recover from for family in case of bus-factor.

I didn’t expect to compete with the major cloud providers on cost, but the architecture I was dreaming of just wasn’t quite feasible even though it’s tantalizingly close...basically, all the benefits of a p2p internal network with all the convenience of NextCloud and all the export-ability of “just copy all these files to a new disk or cloud provider.”

It’s so close, there’s just always some bottleneck: home upload is too slow, cold cloud storage too hard to integrate with / cache, architecture requires too much maintenance, or similar.

I think NextCloud is very close for personal use, if only there was a plug and play p2p backend datastore / cache backed by plug and play immutable cold storage that could pick up new entries from the p2p layer.
