There are four main components for Dynamic Storage Technology.
The NCP Engine provides support for NCP clients and is the main file copy engine for Dynamic Storage Technology. It provides the merged view for NCP users and CIFS users.
Shadow Volume provides the merged file-tree view for NCP client users. The NCP merged view cache is leveraged to provide a merged view for CIFS users.
Beginning with OES 2015, Active Directory users can also access files residing in shadow volumes.
The Dynamic Storage Technology policy engine allows you to create, manage, and enforce policies for a shadow volume pair. You can use the following
Global Policies: Global policies are a set of NCP Server parameters that govern DST behavior. The settings apply at the server level for every mounted shadow volume pair on the server. They do not affect other NCP volumes. For information, see Section 7.0, Configuring DST Global Policies.
Volume Policies: A volume policy applies to one or more specified shadow volume pairs. You can also create a volume policy that automatically applies to all shadow volume pairs. For information, see Section 11.0, Creating and Managing Policies for Shadow Volumes.
