NFS might work. SFTP probably doesn't preserve attributes, but RSYNC might
(with --xattrs option).
If you're using docker with some host folder mounted into the docker, then there's a good chance xattr won't work. I remember filesystem events not working either. Not sure if that's something that can be enabled or if it's just not supported.

If you care about xattr, then the best solution is usually to process files on the NAS or server where reading/writing xattr usually works out of the box.

FileBot generally doesn't require xattr, it just stores some xattr info if possible, but will work just fine without. It's just that the
duplicates script requires them to work, so it'll instantly know which file is which movie/episode without having to bother any web services.
