This could take a very long time to complete and may not complete before the next scheduled backup
to the slot being replicated.
• 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 121 for more
information about using Tape Attach with HP StorageWorks Tape Libraries or Tape Drives. See
“ Recovering a source appliance ” on page 74 for more information about using seeding with Replication
Recovery.

1.
Host backs up to a Non Replicating library on the Source Appliance.
2. The fi rst full backup is copied to a cartridge on a Tape Library.
3. The physical cartridge is shipped to the Data Center.
4. The fi rst 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 con fi gure
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 con fi gure the replication source and target.
