Figure 24. Step 2-Replicate to the Primary Group (Data Available and Protected) 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 the 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. Figure 24. Step 2-Replicate to the Primary Group (Data Available and Protected) Figure 25. Step 3-Fail Back to the Primary Group shows the final step in recovering data - fail back to the primary group. To fail back to the primary group: • Set the recovery volume offline. • Replicate the recovery volume to synchronize volume data across both groups. • Demote the recovery volume to an inbound replica set. • Promote the failback replica set to a volume. You can perform these tasks separately or use the Failback to Primary operation, which encompasses all the tasks. At this point, the volume replication configuration returns to its original state and users can connect to the volume on the primary group. About Data Recovery 277
