The "failback unit" is a Protected Domain. This means all protected VMs in the Domain will be failed back together as part of the same failback task.

    • Identical failback steps are applicable to all Domains unrelated to a Domain’s VM protection scope (zonal or regional) and initial failure nature (partial, full zonal, or regional). VM disk scopes (zonal or regional) are preserved on failback. 
    • AROVA can manage failback from either region. AROVA may remain at the secondary site; however, it is recommended to ultimately move AROVA back to the primary site. AROVA can be returned to the primary site (failback) any time after AROVA Configuration Disk ("ACD") replication has been completed.
    • The following diagram illustrates the secondary and primary regions of AROVA managed disk state machines:
