2. Decide whether you want to use physical tape media to reverse seed the first full restore. It is
possible to recover across the WAN, but this may place an unacceptable load on bandwidth or
time availability.
IMPORTANT:
If using reverse seeding, use Tape Attach on the Target Appliance to copy the last full backup
cartridge to tape and transport the media to the Replication Source site. Import the physical
media into the a slot within a Non-Replicating Library on the Source Appliances (using the Tape
Attach pages) before running the Replication wizard.
3. Go to the Replication - Mapping Configuration page and select the new non-replicating library.
4. Click Start Replication Wizard .
5. Add the Target Appliance that was used as the previous replication target using its IP address
or fully qualified domain name.
6. Select the existing library from which slots should be recovered. Because the slot mappings were
deleted, this library is now a Non-Replicating Library (rather than a Target Library).
7. Remap the slots that were previously in the replication mapping.
8. All slots in the Target Library will be selected by default, but you may unhide the Recovering
checkbox column and select the cartridges that should be recovered. Any not selected will not
be recovered but will be mapped for future replication overwrite.
9. Click Apply to run reverse replication.
10. As soon as reverse replication has completed for each slot, the data may be recovered to the
host using the original backup application.
11. New backups can now run to the Source Appliance and replication will run normally without
further configuration.
Promoting a Target Library over the WAN using SCSI
In this recovery model, a disaster has occurred at the remote site resulting in the loss of both the host
servers and the D2D system. New server hardware has been purchased and installed and the admin
now wants to recover data to the server. The admin however has not installed a new D2D and is
going to recover data directly to the server from the Data Center D2D appliance over the WAN (which
will take a long time).
Before the failure a mapping existed between a Source Library on the remote site D2D and a Target
Library on the Data Center D2D. After the failure the mapping still exists but the Source Library is
missing. The Target Library on the Data Center D2D is still in Target Library mode, it has not had its
mappings removed.
IMPORTANT:
This recovery method is not suitable if the Target Library also has slot mappings from Source Libraries
on other remote sites.
