  • For the paired cloud sites, you do not need to perform additional operations. In a few minutes, the pairing reports a green status and the replications proceed according to their RPO.
  • For the paired on-premises sites, the
    Cloud Service
    reports a red status for all the pairings incoming from on-premises and outgoing to on-premises. The paired
    On-Premises to Cloud Director Replication Appliance
    instances continue to report a green status for pairing to cloud and the replications from on-premises to cloud proceed according to their RPO. To restore the replications from cloud to on-premises, you can restart the
    On-Premises to Cloud Director Replication Appliance
    instances or you can repair all on-premises sites with the cloud site.
You can verify that all services are running correctly. For more information, see Verify uptime and local and remote connectivity in the Cloud site.
