Similarly, it provides an ef
fi
cient option for replicating the
fi
rst instance of data, which contains the full
backup, onto the Target Appliance without placing any load on network bandwidth. (Deduplication
ensures that subsequent replication tasks do not place much load on network bandwidth.) See also

Seeding the Replication Target Appliance
” on page 68.
Preparing for replication
There are 5 major considerations:
•
Make sure you understand the basic concepts and terminology.
•
Decide which deployment model is appropriate for your organization.
•
Map your replication work
fl
ow and decide how the
fi
rst backup will be seeded onto the target
appliance.
•
Con
fi
gure and monitor replication on the Web Management Interface
•
De
fi
ne your Disaster Recovery strategy if the Source Appliance fails.
Replication concepts and terminology
When con
fi
guring appliances for replication, there are some key concepts and terminology that it
is important to understand.
Replication elements
•
Source Appliance:
This is the D2D Backup System with the library device that is being used for
backup by a host server. The library device contains the slots that need to be replicated.
•
Target Appliance:
This is the D2D Backup System with the library device that contains the
replicated slots; it is an exact match of the library on the source HP D2D Backup System. This
appliance needs a replication license.
•
Non-Replicating Library:
This is a library on a D2D Backup System that has not been con
fi
gured
as a source or target for replication cartridge slots.
•
Replication-Source Library:
This is a library on a D2D Backup System that has been con
fi
gured
for backups from a host server and has some or all of its slots con
fi
gured to be replicated. This
library is visible to the host.
•
Replication-Target Library:
This is a library on a D2D Backup System that has been con
fi
gured to
contain slots that are replicants of those in a source library. This library is not visible to the host.
A single HP D2D Backup System may host both Replication-Source and Replication-Target Libraries
and can, therefore, act simultaneously in both Source and Target Appliance roles. However, the host
server will only be able to access Replication-Source or Non-Replicating Libraries. All actions on
Replication-Target Libraries are controlled from the HP D2D Web Management Interface.
