Replication Group Options for Google Cloud Platform

Updated

When you configure a replication group for a Google Cloud Platform destination, identify source instances, and then provide Google-Cloud-Platform-specific values for replication to the destination site.

You can replicate to a Google Cloud Platform destination from Google Cloud Platform source instances.

Note: While replicating instances to a GCP destination using the Deploy virtual machine only during failover option, the software uses a JSON config file to create the instance. The software saves the JSON config file in a storage bucket during the replication operation, and then after the instance is created, deletes the JSON config file. Configure the following permissions for the GCP Service Account in the destination project to create a storage bucket, otherwise replication will fail:

  • storage.buckets.create

  • storage.buckets.delete

  • storage.buckets.get

  • storage.buckets.update

  • storage.objects.create

  • storage.objects.delete

  • storage.objects.get

  • storage.objects.list

  • storage.objects.update

Content Options

  • Name: Enter a descriptive name for the replication group.

  • Source hypervisor: Select the project for the source instances.

    To create a new project, click Create new.

    When you edit an existing replication group, you cannot change this value.

  • Instances: Select the instances to replicate.

Target Options

  • Recovery target: Select a previously defined recovery target.

    To create a new recovery target, click Create new.

    When you edit an existing replication group, you cannot change this value.

  • Frequency: Select the frequency for replication operations.

Advanced Options

  • Unconditionally overwrite if VM already exists: When you select this option, the first replication operation replaces an existing instance with the same name in the target location, even if the destination instance is running.

    Replications that apply incremental updates are not affected by this setting. Incremental updates are applied to the destination instance without overwriting the instance. If the destination instance is currently running, replication fails.

  • Deploy virtual machine only during failover: Select this option to deploy a project only after a failover operation is started.

    By default, when this option is not selected, a destination instance is deployed immediately after a replication operation completes.

Storage / Cache Options

  • Storage: Select the storage pool to use as a recovery store for source data to replicate to the destination site. To create a new storage pool, click Create new.

  • Replicate using secondary copy: To replicate from a secondary copy, select this option.

    • Storage: Select the storage pool to use for secondary copies of source data to replicate to the destination site.

Override Options

  • Override replication options of virtual machines: To change the destination settings for a specific instance, move the toggle key to the right, under Replication configuration, select an instance, and then click Override replication options.

    You can enter override settings for one instance at a time.

    The Edit virtual machine dialog box appears.

    Enter the following information:

    • Instance display name: Enter the display name for the destination instance.

      You can only change this value when adding a new instance.

    • Primary zone: Select the zone in which the replicated disk is created.

      You can only change this value when adding a new instance.

    • Secondary zone: Select the secondary zone in which the replicated disk is created.

      You can only change this value when adding a new instance.

    • Machine type: Select a Google Cloud Platform machine type.

    • Network interface: Select one of the available network interfaces for the instance.

      Note: Static IP addresses from a source instance are not replicated to the destination instance.

    • External IP: To assign a public IP address to Google Cloud Platform instances during replication, select this check box.
