Azure Files is a distributed cloud file system serving file system SMB and REST protocols generally available since 2015. However, because some applications are written for POSIX compliant file systems, our customers wanted to have the same great experience on a fully POSIX compatible NFS file system.
NFS 4.1 support for Azure Files will provide our users with a fully managed NFS file system as a service.
Multiple backup partners including Commvault, Veeam, and Veritas were part of our initial preview and have extended their solutions to work with both SMB 3.0 and NFS 4.1 for Azure Files.
NFS 4.1 support for Azure Files is in a select set of regions today and we will continually add more regions to this list in coming weeks.
