Devices #1 and #2 have different photos/videos/documents that should be backed up at device #3 and hence also available at the other device. Something deleted on #1 should always be easily retrievable from #3.
git-annex and perkeep come closest, but "tagging" and a common store populated by different devices seem to be missing.

The current idea is to organize content into folders, make private torrents of them in a torrents folder, have #Syncthing sync only that folder, and have #BitTorrent propagate the content. All devices would have all the torrent files, and get the content on demand by triggering it in their Bittorrent client.
TODO have meta-data and searchability .. I had hopes on filesystem #xattr but Syncthing seems unreliable for that. How does Bittorrent do with xattr's?
