Which is better SMB or NFS?

Conclusion. As you can see NFS offers a better performance and is unbeatable if the files are medium sized or small. If the files are large enough the timings of both methods get closer to each other. Linux and Mac OS owners should use NFS instead of SMB.

What is NFS and how it works?

NFS, or Network File System, was designed in 1984 by Sun Microsystems. This distributed file system protocol allows a user on a client computer to access files over a network in the same way they would access a local storage file. Because it is an open standard, anyone can implement the protocol.

Is NFS a file system?

Is NFS safe?

NFS itself is not generally considered secure – using the kerberos option as @matt suggests is one option, but your best bet if you have to use NFS is to use a secure VPN and run NFS over that – this way you at least protect the insecure filesystem from the Internet – ofcourse if someone breaches your VPN you’re …

The reason is the NFS write cache, which usually does not get flushed until the file is closed. … So when a client removes a file, it will be gone for good, and the file handle is no longer valid— and and attempt to read from or write to that file will result in a “Stale file handle” error.

Why NFS is not suitable for work anymore?

The NFS device inherently sits directly in the data path, and can’t scale performance to accommodate the demands of I/O intensive computing or multiple concurrent requests. Any gateway is a bottleneck too, and NFS gateways are no exception.

Why is NFS stateless?

NFS is stateless; UDP is used as a transport. If a server fails, the client retries. performance transparency. Caching at the client is used to improve performance.
