A data mover transfers data from primary storage (a NetBackup client) to secondary storage during backups. It also can move data back to primary storage during restores and from secondary storage to tertiary storage during duplication.

For OpenStorage, the NetBackup media servers that connect to the storage server function as data movers. Those media servers must have the vendor plug-in installed on them.

You do not configure OpenStorage data movers explicitly. When you add storage server credentials to NetBackup media servers, NetBackup configures the media servers as data movers.

You can control which data movers are used for backups and duplications when you configure NetBackup storage units.
