The NDMP Snapshot Management Extension Interface leverages the extensibility of NDMP v4 to define a mechanism and protocol for controlling primary storage file system images commonly referred to as snapshots.
Specifically, this interface supports the management of automated and manual snapshot creation, snapshot deletion, and general directory browsing as well as full snapshot recovery and selective file recovery. This interface provides functionality allowing snapshots to be used to implement near-line data protection solutions that offer faster backup and recovery times compared to traditional tape based secondary storage.
