Online mirrors are fine if they have boundaries that make them very certainly append-only.

Opening up scp/rsync and saying "our client only writes new files" is bad. Using a dedicated stream-writing interface over TLS is probably fine.

As for the other attack vector: segregating the admin credentials so that the stream-writing interface cannot be bypassed, yeah, fun. 2FA only gets you so far.
