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.
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.
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 the source storage server.
