Managing NDMP
The FluidFS cluster supports Network Data Management Protocol (NDMP), which is an open standard protocol that facilitates backup
operations for network attached storage, including FluidFS cluster NAS volumes. NDMP should be used for longer-term data protection,
such as weekly backups with long retention periods.
The FluidFS cluster supports remote and three-way backup architecture implementations, wherein a supported, external Data Management
Application (DMA) server mediates the data transfer between the FluidFS cluster and the storage device. The FluidFS cluster supports full,
dierential, and incremental NDMP Level Based Backup (levels 0-9), Full, Incremental/Dierential Token Based Backup, and Direct Access
Recovery (DAR). The FluidFS cluster supports NDMP versions 3 and 4 (default mode).
The FluidFS cluster includes an NDMP server that is responsible for the following operations:
• Processing all NDMP backup and restore requests sent from DMA servers
• Sending all NDMP replies and notication messages to DMA servers
• Transferring data over the network to or from remote NDMP tape or data servers
The NDMP server handles all communications with the DMA servers and other NDMP devices through an XDR encoded TCP
(Transmission Control Protocol) data stream.
