About OpenStorage data movers for backups

A data mover is a NetBackup media server that backs up a client and then transfers the data to a storage server. The storage server then writes the data to storage. A data mover also can move data back to primary storage (the client) during restores and from secondary storage to tertiary storage during duplication.

The data movers host a software plug-in they use to communicate with the storage implementation.

When you configure the storage server, you also select the media servers that host the OpenStorage plug-in. Those media server data movers are assigned the credentials for the storage server. The credentials allow the data movers to communicate with the storage server. NetBackup then 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.
