About the Enterprise Media Manager (EMM)

The Enterprise Media Manager (EMM) is a NetBackup service that manages the device and the media information for NetBackup. The Enterprise Media Manager stores its managed information in a database that resides on the primary server. The NetBackup Resource Broker queries EMM to allocate storage units, drives (including drive paths), and media.

EMM contains the following information:

  • Device attributes

  • Robotic library and standalone drive residence attributes

  • NDMP attributes

  • Barcode rule attributes

  • Volume pool attributes

  • Tape attributes

  • Media attributes

  • Storage unit attributes

  • Storage unit group attributes

  • Hosts with assigned tape drives

  • Media and device errors

  • Disk pool and disk volume attributes

  • Storage server attributes

  • Log on credentials for storage servers, disk arrays, and NDMP hosts

  • Fibre Transport attributes

EMM ensures consistency between drives, robotic libraries, storage units, media, and volume pools across multiple servers. EMM contains information for all media servers that share devices in a multiple server configuration. The NetBackup scheduling components use EMM information to select the server, drive path, and media for jobs.
