PowerStore file supports three-way Network Data Management Protocol (NDMP) backups, allowing administrators to protect file systems by backing up to a tape library or other backup device. In an NDMP configuration, there are three primary components:
Three-way NDMP transfers both the metadata and backup data over the network. The metadata travels from the primary system to the DMA. The data travels from the primary system to the DMA and then finally to the secondary system. Figure 44 shows an example of a three-way NDMP configuration.
PowerStore supports taking NDMP full backups, incremental backups, restores, and tape cloning. Both dump and tar backups are supported, but volume-based backups (VBBs) are not supported. Enable these parameters when running an NDMP backup:
