Creating a Replication Group

A replication group is a set of virtual machines that can be replicated to a replication target (secondary site).

VMs can be replicated to VMware or Amazon from streaming backups, or to VMware using Live Sync Direct from an IntelliSnap backup.

Before You Begin

  • For traditional live sync, virtual machines must have been backed up at least once to be added to a replication group.

    This requirement does not apply for Live Sync Direct.

  • Create a replication target for the secondary site.
  • For Amazon destinations, when replication uses an Amazon instance as the VSA proxy and does not specify a bucket, you must provide guest instance credentials for each guest instance on the Override options page for the replication group, including the domain or computer name, username, and password.


  1. From the navigation pane, go to Configuration > Replication groups.
  2. Click Configure replication group.

    The Configure replication group wizard start page appears.

  3. Click Virtualization.
    • To replicate from streaming backups, click Live Sync.
    • To replicate from an IntelliSnap backup, click Live Sync Direct.

      With Live Sync Direct configurations, a maximum of three VM snapshots are retained on source VMs.

    The wizard displays the Select content page.

  4. Provide the following information:
    • Hypervisors: Select the hypervisor for the source VMs.
    • Name: Enter a descriptive name for the replication group.
    • Select VM group (not applicable for Live Sync Direct): Select an existing VM group.
    • Select VMs (not applicable for Live Sync Direct): After selecting a VM group, select specific virtual machines to be replicated and click OK.

      Only VMs that have been backed up are displayed.

    • Plan: (Live Sync Direct only) Select a previously defined replication plan for the group.
    • Snap engine: (Live Sync Direct only) Select one of the following:
      • Virtual Server Agent Snap to take a VM-level snapshot.
      • Snapshot engine for a storage array to take a hardware snapshot.
  5. Click Next.

    The wizard displays the Select target page.

  6. Provide the following information:
    • Target: Select a previously defined replication target or click Create replication target to create a new replication target.
    • Proxy: Select a VSA proxy that can be used to perform the replication operation.
    • Schedule: The only available option is Immediately after the backup job completes.
    • Click Advanced options to configure the following parameters:
      • Amazon buckets: (Amazon target only) From this list, select a bucket for the instance volumes. Buckets are logical containers that provide secure access to objects (such as instance volumes).
      • Validate destination VM (Power ON and OFF): Select this option to verify that the destination VM is bootable by powering it on and then powering off. Changes resulting from the power on are not preserved. If guest tools are not installed on the source VM, validation is skipped even when this option is selected.

        If validation fails, the destination virtual machine reverts back to its last valid (bootable) state.

      • Unconditionally overwrite if it already exists: When this option is selected, the first Live Sync operation replaces an existing virtual machine with the same name in the target location, even if the destination VM is running.

        Live Syncs from incremental backups are not affected by this setting. Subsequent incremental backups and Live Sync updates are applied to the destination VM without overwriting the VM. If the destination VM is currently running, the Live Sync fails.

      • Number of recovery points: (VMware target only) Enter the maximum number of recovery point snapshots to retain on the destination site. Each recovery point snapshot represents the state of a VM that you can choose when performing a point-in-time failover.
      • Disk Provisioning: (VMware target only) Select the disk provisioning type for the destination VM: Original, Thick Lazy Zero, Thin, or Thick Eager Zero.

        When configuring a domain controller VM for live sync, select Thick Lazy Zero.

      • Transport mode for VMware: (VMware target only) Use Auto to have the transport mode selected automatically based on the environment, or select a different value from this list: SAN, Hot Add, NBD, or NBD SSL.
      • Copy precedence: Select the backup copy that should be used as source for the replication operation.
  7. Click Next.

    The wizard displays the Override options page.

  8. To change the destination settings for a VM, select the VM from the Virtual machine list. You can enter the following information:
    • Amazon target:
      • Change instance display name to: Enter the display name for the destination instance.
      • Availability zone: Select the destination zone.
      • Network: Select a network interface for the destination instances.
      • Auto select security group: To specify a specific security group, clear this selection and, from the Security groups list, select a security group for the destination instances.
      • Auto select instance type: To specify a specific instance type, clear this selection and from the Instance type list, select an instance type that provides the available CPU cores and memory for the instance.
      • Specify guest credentials: Select this option to enable required drivers to be installed on the Amazon guest instance, and then provide values for the Domain / Computer name, Username, and Password boxes.

        Note: When replication uses an Amazon instance as the VSA proxy and does not specify a bucket, you must provide guest instance credentials for each guest instance.

    • VMware target:
      • VM display name: Enter the display name for the destination VM.
      • Destination host: Click Browse to select a host for the destination VM.
      • Datastore: Select a datastore to be used for virtual machine disks.
      • Resource pool: Select a resource pool for the destination VM.
      • Network settings: Click Add to create a new mapping between a source network and a destination network.
      • IP address settings: Click Add to customize IP address settings.
  9. Click Next.

    The wizard displays the Summary page showing the settings for the group definition.

  10. Click Finish to create the replication group.


The wizard creates a replication schedule and a replication group that includes the selected source VMs.
