# Replication Target Options for Google Cloud

When you configure a replication target for Google Cloud, provide Google Cloud-specific values for the destination site.

- Select vendor: Select Google Cloud.

- Target name: Enter a descriptive name for the destination (for example, Auto Recovery site 1).

- Destination hypervisor: Select the destination project.

- Access node: Select an access node or an access node group to use for replication to the destination project.

  Note

  The access node group must contain Google Cloud (GC) proxies because you can perform restore/replication operation using GC proxies only.

  To restore multiple instances or VMs simultaneously, select Automatic to distribute the workload (instances or VMs) in the auto recovery job across the access nodes that are assigned for the destination hypervisor. This option is available for operations both from streaming backups or IntelliSnap backup copies.

  First, the instances are assigned to the access nodes by a zone match. If access nodes are not available in the same zone, then the instances are assigned to access nodes in the same region. If there is no zone or region match, the access nodes are assigned using the round-robin method.

  If you select an access node group to restore VMs, the Commvault software distributes the workload (instances or VMs) in the restore job across the access nodes (also called proxies) that are available in the access node group.

- Users and user groups: Select items from the list and click OK to associate users or user groups with the replication target.

- Instance display name: Select Prefix or Suffix, and then enter a text string that will be appended to the original display name to create new destination instance names.

- Primary zone: Select a primary zone for the disk.

- Secondary zone: Select a secondary zone for the disk. This option is applicable only if the source instance has a regional disk configured.

- Machine Type: Select the machine type for the VM. The default value is Auto select, which uses the same configuration as the source VM.

- Service Account: Specify the service account to associate with the VM. The default is Compute Engine default service account.

- Access Scope: Specify the Cloud API access scope for the VM. The default value is Same as source.

- External IP: To assign a public IP address to the instances, select this check box.

- Users and user groups: Select the users and/or user groups that can use this replication target.

- Sole-tenant nodes: Click Browse to select the nodes or node groups you want to be associated with the restored instance.

  Note: The Node affinity dialog box lists all available node groups. However, you can only select the node groups that are supported for the specified machine type.

- Custom metadata: Type the custom or predefined key-value pairs associated with the scripts you want to run when the instance restores.

  The replicated VM will have the key-value pairs in the Custom metadata section on the VM instance details page on the destination VM.

  - For more information about predefined key-value pairs on Linux, go to Using startup scripts on Linux VMs on the Google Cloud documentation website.

  - For more information about predefined key-value pairs on Windows, go to Using startup scripts on Windows VMs on the Google Cloud documentation website.

- Encryption: You can select an encryption key for the restored instances as follows: -Same as source (default value): The encryption key that is used for the instances that you are restoring. -Google-managed encryption key:Keys that are provided and managed by Google Cloud. -Other encryption keys: Encryption keys that customers manage, including CMEK keys, which are provided by Google Cloud and managed by customers using a cloud key management system (KMS). ///note | Note When you're restoring a VM to a project using an encryption key for the first time, ensure that the service account has the necessary permission to both encrypt and decrypt data using the selected Cloud KMS (Key Management Service). If not, grant this permission to proceed with restoring your project using the customer-managed key. /// Because customer-supplied encryption keys are not supported for restores, they are not available for selection. To select an encryption key from a different Google Cloud project, click Switch project, and then select the project. To restore with encryption, the Google Cloud account that gives Commvault access to the instances that you back up must include certain permissions. For information, see Service Account Permissions for Google Cloud.

- Network Tags: Customize network tags to control firewall rules and routing behavior for instances.

  1. To add, replace or delete network tags on the Destination VM, click the Edit button .

  2. In the Choose an action drop down list, select Add, Replace, or Delete as needed.

## Override Options

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

    - Service Account: Add Service Account to be associated to the VM. Default is Compute Engine default service account

    - Access Scope: Add Cloud API Access Scope to be set on VM. Default value is Same as source instance

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

    Note

    Static IP addresses from a source instance are not recovered to the destination instance.

  - External IP: To assign a public IP address to Google Cloud instances during recovery, select this check box.

- Sole-tenant nodes: Click Browse to select the nodes or node groups you want to be associated with the restored instance.

  Note

  The Node affinity dialog box lists all available node groups. However, you can only select the node groups that are supported for the specified machine type.

- Custom metadata: Type the custom or predefined key-value pairs associated with the scripts you want to run when the instance restores.

  The replicated VM will have the key-value pairs in the Custom metadata section on the VM instance details page on the destination VM.

  - For more information about predefined key-value pairs on Linux, go to Using startup scripts on Linux VMs on the Google Cloud documentation website.

    - For more information about predefined key-value pairs on Windows, go to Using startup scripts on Windows VMs on the Google Cloud documentation website.
