I have a samba share running on my server (just an Intel N100 Mini PC). It’s running Fedora Atomic and my desktop is also running Fedora Atomic.
While it’s good enough to watch videos on, reliability when it comes to uploading files to it has been very poor. The connection ends up timing out after a few minutes of uploading.
I found that using rsync to upload files to it has been a lot more reliable.
I’ve never had any issue with file transfers apart from being a bit slower than NFS. The main issues I have with it is lack of Unix file permissions and not allowing all characters in file names.
Unless you need compatibility with windows, you are better off using NFS or SSHFS.
NFS lacks security unless it’s NFSv4 paired with Kerberos AFAIK.
