Table 1-2Terminology(continued)DefinitionTermAn NDMP server application runs on an NDMP host and runsbackup, restore, and device control commands that it receivesfrom an NDMP-conformant backup application. The backupapplication (NetBackup) is considered an NDMP client. Aseparate instance of an NDMP server process exists for eachconnection to an NDMP client. That is, if two backups are inprogress, an NDMP server process exists for each backup.NDMP server applicationAn NDMP storage unit stores the backup data for an NDMPhost. The tape drives in this storage unit attach directly to theNDMP host or can be configured on a SAN. Note that NDMPstorage units cannot be used to store data for non-NDMPhosts, and NetBackup disk storage units cannot be used forNDMP tasks.NDMP storage unitIn a redirected restore, files are restored to a client other thanthe one from which they were originally backed up. InNetBackup for NDMP, the restore data travels from an NDMPhost (or NetBackup media server) with a locally attachedstorage device to another NDMP host on the network.Redirected restore (to adifferent client)A form of three-way backup and restore also known as NDMPbackup to Media Manager storage units. Data travels froman NDMP host to a tape drive that is attached to a NetBackupmedia server.See“Configuring NDMP backup to Media Manager storageunits”on page 66.Remote NDMPIn a three-way backup or restore, data travels between anNDMP host and a storage device that is attached to anotherNDMP host or to a NetBackup media server. This backupcontrasts with local NDMP backup or restore where the datatravels between an NDMP host’s disk and a storage devicedirectly attached to the same NDMP host.
