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 Media Server Deduplication Pool
or a PureDisk Deduplication Pool. The destination storage unit cannot be the
same as the source storage unit.
If the destination is a PureDisk Deduplication Pool, 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 2-3 shows 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:
