About MSDP push duplication within the same domain

The local deduplication node contains normal backups; the remote deduplication node is the destination for the optimized duplication copies. Load balancing server LB_L2 has credentials for both storage servers; it is the common server.

Because all hosts in the local node are co-located, you can use any available media server for the backups.
Figure: Storage unit settings for duplication to MSDP_R shows the storage unit settings for the optimized duplication. The destination is the in the remote environment. You must select the common server, so only load balancing server LB_L2 is selected.
If you use the remote node for backups also, select and load balancing server in the storage unit for the remote node backups. If you select server , it becomes a load balancing server for the remote . In such a case, data travels across your WAN.
