Query on FileRest vs SMB/NFS.

Divyanshu Gupta 20 Reputation points

Hi Microsoft Community,
I was reading through the Azure File REST API documentation for an integration use case. I came across this page where it's specified that NFS file shares are not supported (https://learn.microsoft.com/en-us/rest/api/storageservices/operations-on-directories). Could you specify what NFS file shares mean here? Would it be inaccessible by File REST API once it is mounted on a Linux client using NFS protocol? What is the dependency of the protocol used on the REST API calls? What are the other limitations we need to keep in mind w.r.t. file shares that cannot be accessed by this API?
Please refer to this too https://learn.microsoft.com/en-us/rest/api/storageservices/operations-on-files.

    @Divyanshu Gupta Apologies for the delay response!

    When you create an SSD file share, you have a choice between the SMB and NFS protocol. After you’ve created the file share, this property is unchangeable. NFS file shares do not support FileREST today. It has nothing to do with NFS clients having mounted the share with NFS, it just doesn’t support FileREST at all. 

    We are adding support for FileREST on NFS file shares. The primary reason we are doing this is to enable value added services, like Azure Backup or Storage Mover, on NFS file shares. This should be coming later this year. We don’t have an ETA for now.
