Yes, I like it. But needs to be more robust still. Like nostr. So that if one provider goes down there are others. You also need your own profile history versioned, which is a bit more detail.

If the archive packages are of standard format and you can do hot swaps that handle duplicities and other redundancies gracefully isn’t that pretty much there?
Users have their backups, relays go have theirs etc. You just need to have enough backups flying around that it covers the space. And assuming relays fail and everything fails at times like the Netflix fault tolerant philosophy.
The versioning and media files might be solved with nostr:npub1h0rnetjp2qka44ayzyjcdh90gs3gzrtq4f94033heng6w34s0pzq2yfv0g
Does Nostr require some kind of distributed RAID for the overall data? Indexing relays are in a good place to see the gaps.
