You can use the NFS protocol to present a staging disk to a server for data
capture. NFS protocol can also be used to present virtual clones of
point-in-time captured images.
Whether an application is captured to an NFS staging disk is determined when the
application host is added, see
Manage hosts and their connected applications for details. If a host is
set to NFS, then all applications on that host is captured to an NFS
staging disk.
The required open bidirectional TCP/UDP ports to utilize NFS transport are:
