You reconfigure a replication to change the RPO settings, the number of replication instances to keep, or the quiescing method that is applied when synchronizing the replication source virtual machine to your cloud organization.

Cloud replications appear in the Forward Replications list on the Replications tab in Site Recovery.

Procedure

  1. Log in to the vSphere Client or vSphere Web Client.
  2. On the home page, click Site Recovery and click Open Site Recovery.
  3. On the Site Recovery home page, select the site pair to the cloud provider site and click View Details.
  4. Click the Replications tab and click Forward replications.
  5. Select the replication you want to reconfigure from the list and click the Reconfigure icon.
  6. On the Replication settings page of the Reconfigure Replication wizard, use the RPO slider to set the acceptable period for which data can be lost if of a site failure occurs.
  7. (Optional) To save multiple replication instances that can be converted to snapshots of the source virtual machine during recovery, select Enable point in time instances and adjust the number of instances to keep.
    Note:

    You can keep up to 24 instances for a virtual machine. For example, if you configure vSphere Replication to keep 6 replication instances per day, the maximum number of days you can set is 4 days.

    The number of replication instances that vSphere Replication keeps depends on the configured retention policy, but also requires that the RPO period is short enough for these instances to be created. Because vSphere Replication does not verify whether the RPO settings will create enough instances to keep, and does not display a warning message if the instances are not enough, you must ensure that you set vSphere Replication to create the instances that you want to keep. For example, if you set vSphere Replication to keep 6 replication instances per day, the RPO period must not exceed 4 hours, so that vSphere Replication can create 6 instances in 24 hours.

  8. (Optional) Enable quiescing for the guest operating system of the source virtual machine.
    Note:

    Quiescing options are available only for virtual machines that support quiescing. vSphere Replication does not support VSS quiescing on Virtual Volumes.

  9. (Optional) Select Enable network compression for VR data.

    Compressing the replication data that is transferred through the network saves network bandwidth and might help reduce the amount of buffer memory used on the vSphere Replication server. However, compressing and decompressing data requires more CPU resources on both the source site and the server that manages the target datastore.

  10. On the Ready to complete page, review the replication settings, and click Finish.
