A replica represents the contents of a volume at a specific point in time. Yo
u can create replicas on-demand and
through schedules.
• Failover and failback. If a v
olume is destroyed, you can fail over to the recovery group and recover data from
a replica. Users can then resume access to the recovery volume. When the original volume becomes available,
you can failback to the original group.
