Hi,
when it comes to replication with you StoreOnce devices, you first need to decide to use Catalyst mode or VTL mode. In VTL mode you need a replication license on the target and the replication is configured directly on the StoreOnce system. Hence, in Data Protector you would create the VTL devices in the same way as you configure physical devices. When using the Catalyst mode (preferred), you just create a store for each type of data and within Data Protector you create an object copy job to replicate between the StoreOnce systems. In Catalyst mode you need the Catalyst license on each StoreOnce system.
When going to www.hp.com/go/storeonce, you can get additional information, including best practice tips how to configure, how to use, ...
Best regards
