Generic NDMP Backup and Restore Variations

DPX provides generic NDMP support that can back up and restore data for NDMP NAS appliances in several ways.

• High-Speed Local Backup

  The NAS appliance is directly connected to a SCSI-attached or fiber-attached storage device (typically a tape drive). The NAS appliance must be defined in DPX as a node that uses the NDMP access method. DPX documentation refers to these nodes as NDMP nodes. Data is backed up and restored directly via the local device.

• Three-Way Backup

  The NAS appliance sends data over the LAN to a storage device attached to a second NDMP appliance. Both NDMP devices (source and destination) must be defined in DPX as nodes that use the NDMP access method.

• Appliance-to-Server Backup

  The NAS appliance sends or receives data over the LAN to a DPX device server. The NAS appliance must be defined in DPX as a node that uses the NDMP access method. The DPX device server is defined in DPX as system type TCP/IP, though DPX device servers can exchange data with supported NDMP devices.
