Group Administration Data recovery
13–6
Figure 13-4 shows the second step in recovering data—replicate to the primary group. When the primary group is
available:
• Demote the original volume to a failback replica set.
•
Replicate the recovery volume to th
e primary group.
Note: If the failback snapshot is not available on the primary
group, the first replication transfers all the
recovery volume data, instead of only the changes that users made to the recovery volume.
You can perform these tasks separately, or use the Replicate to Primary
operation, which encompasses both tasks.
