Host D is configured as a load balancing server for node A

The following are the requirements for optimized duplication:

■The source images must be on a NetBackup media server deduplication pool.

■The destination disk storage can be another MediaServerDeduplicationPool or a PureDiskDeduplicationPool. The destination storage unit cannot be the same as the source storage unit.

If the destination is a PureDiskDeduplicationPool, the PureDisk environment must be at release level 6.6 or later.

■At least one media server must be common between the source deduplication node and the destination, as follows:

■If the destination is another Media Server Deduplication Pool: Configure a server in the destination deduplication node as a load balancing server for the source storage server.

For example, Figure 2-3shows two deduplication nodes. Host D from the destination node is configured as a load balancing server for the source node. It is the common host. The following Storage Server Configuration Wizard screen shows the load balancing servers that are configured for deduplication node A:
