Just learned about P2P and syncthing. Is there a difference between P2P file-sharing and a self-hosted server with hosting something like nextcloud? Is one easier to setup/maintain than the other? More secure?Hardware requirements for scaling up? Or is there no difference if its all smaller scaled and self-hosted?
Nextcloud is more like a “star” configuration, where Nextcloud is the server, with multiple clients. Of course the clients can cache data from Nextcloud.
Syncthing is more like a mesh, where each client serves data to others (although this is configurable),
Nextcloud has way more features, like shared calendars, video conferencing plugins etc, which is great, but may be overkill for your needs.
I use both, although NextCloud/OwnCloud fits my needs better.
I would say syncthing is easier to set up. There is more admin overheard (esp upgrades) with NextCloud/OwnCloud.
