  • How to Set Up NFS Server and Client on Ubuntu 20.04

    NFS (Network File System) is a distributed file system protocol that allows a user on a client computer to access files over a computer network much like local storage is accessed. It is a popular, cross-platform and distributed file system protocol used to export local file systems over the network so that clients can share directories and files with others over a network and interact with them as though they are mounted locally. 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.

    Ubuntu 20.04 supports NFS version 3(NFSv3) and 4(NFSv4). The default NFS version is 4.2 which features support for Access Control Lists (ACLs), server-side copy, sparse files, space reservation, labeled NFS, layout enhancements, and much more.
