I want to connect nfs to microtics for backups. But I did not really find any information on how to do this. It seems that Mikrotik supports this technology. It seems that there is no easy way.
Someone set up? Or can suggest something?

If there's NFS support in RouterOS, then it's extremely well hidden, I haven't seen anything like that in last more than ten years. So for me the more likely explanation is that it isn't there.
