If the storage server does not require logon credentials, you must enter dummy
credentials so that NetBackup configures the media servers as data movers.
About OpenStorage data movers
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.
See “About OpenStorage storage servers” on page 61.
About the OpenStorage plug-in
A software plug-in must reside on every data mover. The plug-in must conform
to the Symantec OpenStorage API specification. The vendor exposes the storage
capabilities to NetBackup through the plug-in.
The plug-in depends on the storage implementation, as follows.
■
For appliance storage, the appliance vendor provides the plug-in. The vendor
should provide information about how to install the plug-in.
To determine a disk appliance’s capabilities, NetBackup uses the plug-in to
query the storage appliance. Capabilities can include deduplicated storage,
optimized off-host duplication, and so on.
See “About installing the disk appliance plug-in” on page 78.
■
For Nirvanix cloud storage, the plug-in is installed with NetBackup; no separate
installation is required.
