During filer-to-filer backup operations that use NDMP (network data management protocol) and are not stored in the Tivoli® Storage Manager server storage hierarchy, the network-attached storage (NAS) file server controls the format of the data written to the tape library.
The NDMP format is not the same as the data format used for traditional Tivoli Storage Manager backups. When you define a NAS file server as a data mover and define a storage pool for NDMP operations, you specify the data format. For example, you would specify NETAPPDUMP if the NAS file server is a NetApp or an IBM® System Storage® N Series device. You would specify CELERRADUMP if the NAS file server is an EMC Celerra device. For all other devices, you would specify NDMPDUMP.
