The API that makes it happen is OST and the 'scheduler', if you will, is a Storage Lifecycle Policy.

The high level configuration is to setup two storage servers, two disk pools, and two storage units (one for each dedup device). You then configure a Storage Lifecycle Policy to do the initial backup to the local dedupe device (the local storage unit with the local disk pool) and a duplication step that points to the remote dedupe device (which is the remote storage unit pointing to the remote disk pool). The replication shows up as a duplication job in NBU and the job details will show it is using Optimized Duplication, so it only replicates the unique data.

Unfortunately, there currently is no easy way to see how much unique data is sent, NBU only knows about the full image size.

If, instead of the above method, you were to use the dedupe device's included replication, NetBackup will not be aware of the data on the remote device.
