The Media server setting specifies one of the following:

• The NetBackup media server where the drives in the storage unit attach.

• The NetBackup media server that controls the disk storage unit.

• The NetBackup media servers that can write data to and read data from the disk pool.

• The NetBackup media servers that can move data to and from the disk pool.

• The NetBackup media servers that function as deduplication servers.

Consider the following items, depending on the type of storage:

• BasicDisk storage

  To configure a disk storage unit, select a single media server.

• AdvancedDisk storage units

  The Media server setting specifies the NetBackup media servers that can write data to and read data from the disk pool.

  The media servers that are configured as storage servers appear in the media servers list. The disk storage must be directly attached to the media server that is configured as the storage server.

  NetBackup selects a media server when the policy runs.

• NDMP storage

  To configure an NDMP storage unit, the Media server setting specifies the name of the media server that is to back up the NDMP host. Only those media servers that can talk to the specified NDMP storage device appear in the drop-down menu.

  An NDMP host can be authenticated on multiple media servers. Select Any Available to have NetBackup select the media server and storage unit at the time the policy is run.

• OpenStorage storage units

  The Media server setting specifies the NetBackup media servers that can move data to the storage server.

  To allow any media server in the media server list to access the storage (default), select Use Any Available Media Server.

  To restrict the media servers that can access the storage, select Only Use The Following Media Servers. Then select the media servers that are allowed to access the storage.

  The following is required on each media server that accesses the storage:

  • The vendor's software plug-in is installed.

  • The login credentials to the storage server are configured.

  Only the media servers on which storage server credentials are configured appear in the media servers list. If a server does not appear, verify that the software plug-in is installed and that login credentials are configured for that media server.

  Note:

  Run the tpconfig command line utility directly on the media server to configure and verify credentials.

  NetBackup selects a media server when the policy runs.

• SharedDisk storage units

  See About SharedDisk support in NetBackup 7.0 and later.

• PureDisk storage units (media server deduplication pool and PureDisk deduplication pool)

  To allow any media server in the list to deduplicate data, select Use Any Available Media Server.

  To restrict the media servers that can deduplicate data, select Only Use The Following Media Servers. Then select the media servers that are allowed to deduplicate the data.

  Each media server must be configured as a deduplication media server.

  See About deduplication servers.

• PureDisk storage units (PureDisk Deduplication Option storage pool)

  To allow any media server in the list to access the storage (default), select Use Any Available Media Server.

  To restrict the media servers that can access the storage, select Only Use The Following Media Servers. Then select the media servers that are allowed to access the storage.

  NetBackup selects a media server when the policy runs.

  The following is required on each media server that accesses the storage:
