About optimized duplication of deduplicated data

If you use your destination storage unit to back up clients, you can create a different storage unit for those jobs. In that storage unit, select all of the hosts in that node that you want to use for deduplication.

If you select the common server from the destination node in the source node storage unit, NetBackup uses i5 for deduplication. Therefore, do not select it in the storage unit for source node (unless you want to use it for the source node).

For example, for the storage unit for the backup jobs for node A in Figure 2-3, do not select Host D (shown in the following figure):

Optimized deduplication copy limitations

The following are limitations for optimized deduplication copy:

■NetBackup does not support a PureDisk storage pool as the source for optimized duplication. Therefore, you cannot use optimized duplication from a PureDisk storage pool to a media server deduplication pool or to another PureDisk storage pool.

■If an optimized duplication job fails, NetBackup does not run the job again. See “Configuring optimized deduplication copy behavior” on page 57.
