End To End Disaster Recovery Process; End To End Recovery - Robo Scenario - HP D2D Manual

7 End to End Disaster Recovery Process

In this section we will explain the process for recovering from a replica D2D NAS share having
made use of the low bandwidth replication feature of HP D2D NAS.
We will cover three scenarios:
A ROBO site where the CommCell is still available but the local data is lost (recover data from
the Disaster Recovery site)
A Data Center to Data Center scenario where a complete CommCell installation has been
lost (total recovery from Disaster Recovery site)
A scenario where the D2D Backup System at the target site is also copied to physical tape
for archiving and security
End to End Recovery – ROBO Scenario
This typical usage model is a large ROBO deployment with the Commserve in a central location.
In this scenario, there are two D2D Backup Systems, one located at a ROBO site and one located
at the central location. Low Bandwidth Replication is configured between the two D2D Backup
Systems to enable data written at the ROBO location (Site A) to be replicated to the Disaster
Recovery location (Site B). A CommVault Media Agent server, in this case the Commserve, is
configured to utilize both D2D Backup Systems, one as the primary read/write device; the other
as a secondary read-only device.

Recovery steps are as follows.
1. Configure D2D NAS shares on Site A and Site B from the D2D Web Management Interface.
2. Configure replication between the D2D-A & D2D-B NAS shares.
