About installing and configuring Network File System (NFS) for SharePoint Granular Recovery
NetBackup uses Granular Recovery Technology (GRT) and Network File System (NFS) to recover the individual objects that reside within a database backup image, such as:
A user account from an Active Directory database backup
Email messages or folders from an Exchange database backup
A document from a SharePoint database backup
The NetBackup client mounts and accesses a mapped drive over a secure connection to the NetBackup media server. The NetBackup media server handles the client requests through the NetBackup File System (NBFS) service, or NBFSD.
Multiple NetBackup agents that support GRT (for example, Exchange, SharePoint, and Active Directory) can use the same media server.
