NFS Protocol
In this article
If the NetApp storage system operates over NFS, you do not have to install any additional licenses to use Backup from Storage Snapshots.
For Backup from Storage Snapshots, Veeam Backup & Replication creates a snapshot of a volume on which the NFS share with VM data resides. The created volume snapshot is used as a source of data. Veeam Backup & Replication starts its native NFS agent on the backup proxy and uses it to read data from the “cloned” NFS share on the volume snapshot.
