• If the Target Appliance is not yet in use, it may be possible to colocate the Source and Target
Appliances on the same site LAN to perform the initial replication locally on a high bandwidth
link and then ship the appliance to the Data Center.
• If the Target Appliance is already in use, use the Library or Tape Attach Copy functionality to
create a physical cartridge that can be shipped to the site of the Target Appliance and imported.
You only need to seed with one full backup. See “Using Tape Attach” on page 147 for more information
about using Tape Attach with HP StorageWorks Tape Libraries or Tape Drives. See
“Recovering a source appliance” on page 94 for more information about using seeding with Replication
Recovery.

Figure 45 Seeding initial data using Tape Attach
1. Host backs up to a Non Replicating library on the Source Appliance.
2. The first full backup is copied to a cartridge on a Tape Library.
3. The physical cartridge is shipped to the Data Center.
4. The first full backup is imported from Tape Library into a Non-Replicating Library on the Target
Appliance.
5. Once imported create the replication linkage between Source and Target Appliances and configure
slot mappings.
6. Normal replication across the WAN can now take place with only new or changed data needing
to be replicated.
IMPORTANT:
With this option, initial data must be seeded onto a Non-Replicating Library before you use the Web
Management Interface to configure the replication source and target.
