FileBot Thanks, looks promising. Only problem closed source. I do not mind to pay for license, but do not like running unknown code on my server.

Yeh, it seems the only good way. But will bring so much not needed function to the mix.

Thanks, I will check out TinyMediaManager.

NFS / Shares - over complicated. Just syncthing it around (and snapshot on backup server), for nearly static data as music it is perfect.

albums one by one with --timid flag. You are using Navidrome , than you music should be well tagged already. Should be fast and easy, just repeat it 2000 time. You can also disable lockups and just import “as is” if you trust your taggig

nfs over the internet is usually bad idea. Network delays is killer for NFS. You can use ssh instead. And add some mbuff for better results.
