Restoring Multiple Full Amazon EC2 Instances Out of Place

You can restore multiple full Amazon EC2 instances to a different AWS Region and/or AWS account (out of place).

Prerequisites

Start the Restore Wizard

  1. From the Command Center navigation pane, go to Protect > Virtualization.

    The Overview page appears.

  2. On the VM groups tab, in the row for the VM group that contains the EC2 instances that you want to restore, click the action button action_button, and then click Restore.

    The Select restore type page appears.

  3. Click Full instance.

    The Full instance page appears.

  4. Select the check boxes for the EC2 instances to restore.

    To select all the instances, select the check box above the list of instances.

  5. To select a specific source copy and/or MediaAgent for the restore, in the upper-right area of the page, click Change source.

    By default, the Commvault software automatically selects the MediaAgent and source copy as follows:

    • MediaAgent: The software uses the MediaAgent that performed the backup.

    • Source copy: By default, the software searches for the requested data in the primary copy. If the data is not found in the primary copy, the software selects a secondary or auxiliary copy.

    Potential for egress charges

    Restoring from a copy that is outside the destination Region incurs egress charges. For more information, see Data Transfer on the Amazon EC2 On-Demand Pricing page in the AWS documentation.

    For more information, see MediaAgent and Copy Precedence Considerations for Virtualization Restores.

  6. Click Restore.

    The restore wizard appears.

Specify the Restore Destination

  1. For Type, select Out of place.

  2. For Restore as, leave Amazon Web Services selected.

  3. From the Destination list, select the AWS account to restore the EC2 instances to.

  4. For Access node, leave Automatic (the default value) selected, or select an access node or an access node group.

    • For the best results, use the Automatic option because it does the following:

      • Selects the most appropriate access nodes.

        Potential for egress charges

        The Commvault software assigns the EC2 instances to access nodes as follows:

        1. To access nodes in same AZ.

        2. If no access nodes in same AZ are available, to access nodes in same Region.

        3. If no access nodes in the same Region are available, to any available access node (which incurs egress charges).

      • Provides resiliency against access node failure (that is, if an access node fails during a restore, the software restarts the restore on other, available access nodes).

      • Distributes the workload across the access nodes that are assigned for the destination AWS account.

    • If you select a specific access node or access node group, consider the following:

      • If you select an access node that is outside of AWS, the software uploads volume information to Amazon S3 and uses the volumes to create the EC2 instance.

      • If you select an access node group, the software distributes the workload across the access nodes that are available in the access node group.

    Potential for egress charges

    When you restore EC2 instances from an Amazon S3 library in one AWS Region to another Region, consider Amazon Virtual Private Cloud (VPC) egress costs. For more information, see Data Transfer on the Amazon EC2 On-Demand Pricing page in the AWS documentation.

  5. Click Next.

    The Virtual Machines page appears.

Configure Restore Options for the EC2 Instances and the EBS Volumes

  1. To configure the restore options for one or more EC2 instances, select the instances, and then click Configure restore options.

    The Configure restore options dialog box appears.

  2. For the names of the restored EC2 instances, you can add a prefix and/or a suffix.

    For example, you can add a suffix of "-restored".

    The Commvault software sets the AWS Resource Tag 'Name' to the value that you enter in VM display name. For information about which characters are supported for AWS Resource tags, see Tagging your AWS resources in the AWS documentation.

  3. For Availability zone, select the AZ to restore the EC2 instances to.

  4. For Instance type, select the EC2 instance type for the restored instances.

    The Automatic option attempts to restore the instances as the same EC2 instance type as the source.

  5. For Key pair, enter the Amazon EC2 key pair to access the restored EC2 instances.

  6. For Network settings, specify whether to use the source network configuration or a different configuration:

    • To re-create the source network (VPC, Subnets, Security Groups, elastic network interfaces, ENIs) as part of the restore, move the Restore source network configuration toggle key to the right.

    • To restore to an existing VPC in the destination AWS account, do the following:

      1. If you are installing to a new AWS account or AWS Region and you want the Commvault software to create your VPC and related resources as part of the restore of the EC2 instance, move the Restore source network configuration toggle key to the left.

      2. For Network, to select an VPC network, subnet, and ENI, do the following:

        1. Click the browse button.

          The Select network settings dialog box appears.

        2. Select an existing ENI or create a new ENI.

          When you create a new ENI, you can specify an IP address.

        3. Click Save.

      3. To specify a custom IPv4 primary IP address for Network Interface 1 (Primary Interface) for the restored EC2 instances, in Private IP address, enter the IPv4 address.

        Note

        If you enter an IP address that is not within the available range or that is already in use, the restore fails.

      4. For Security groups, do one of the following:

        • To have the software attempt to assign the same security group from the source EC2 instances to the restored instances, select Auto-assign.

        • To select a security group from the AWS account that you're restoring the intances to, select Custom, and then select the security group.

  7. For Volume options, modify the settings for EBS volumes as follows:

    • You can select one or more volumes to modify.

      If you select multiple volumes, and the volumes have different values for either Volume type or KMS key, then Leave value unchanged is displayed for that setting. Consider the following points:

      • Leave value unchanged indicates that the restored volumes will have the same value as the source volumes.

      • You can select a different value, and the value that you select applies to all the volumes that you are modifying.

    • For backups from Commvault Platform Release 2024 (11.34) and previous releases, in Volume type and KMS key, Original is displayed. Original indicates the type of the source volume.

    • For Volume type, the options are limited to only those that are supported for the volume size.

      Volume types that are not supported for the volume size are visible, but not available to select.

      To see why a volume type is not available/not supported, hover over the volume type to view the minimum and maximum supported volume sizes for the volume type.

    • If IOPS applies, given the volume type, then you can modify the value.

      After you click Save, the Commvault software validates the value you enter. If the value is not in the supported range for the EBS volume type, the software displays the minimum and maximum supported values. Enter a value that is in the supported range, and then click Save.

    • If Throughput applies, given the volume type, then you can modify the value.

      If you modify the value, as you are typing, the Commvault software validates the value you enter and briefly displays the minimum, maximum, and baseline values. If you enter a value that is not in the supported range for the EBS volume type, after you click Save, the Commvault software displays the minimum and maximum supported values, and you cannot click Save until you enter a value that is in the supported range.

      After you click Save, the Commvault software validates the value you enter. If the value is not in the supported range, the software briefly displays the minimum, maximum, and baseline supported values. Enter a value that is in the supported range, and then click Save.

      Note

      Some Amazon EBS volumes require a specific IOPS and throughput ratio. Verify both that your IOPS and throughput values are within the supported ranges for those values and that the ratio between your values is supported.

    • For KMS key, select an encryption key or option:

      Important

      • Commvault recommends that you enable default encryption of EBS volumes in each AWS account that creates EBS volumes. For information, see Enable encryption by default in the AWS documentation.

      • The followng key types are supported:

        • AWS managed keys

        • AWS owned keys

        • Customer managed keys, including multi-region keys

      • Auto: This option is available for restores to a different AWS Region.

        The Auto option looks up the default KMS key for EBS encryption using the ec2:GetEbsEncryptionByDefault action (if permitted by the identity that is performing the restore).

      • No encryption: This option is not recommended. The AWS Well-Architected Framework (SEC08-BP02) recommends enforcing encryption at rest for sensitive data.

  8. For Disable tags, if the source EC2 instances have AWS resource tags, then those tags are displayed in the VM tags area (excluding the Name tag and the AWS reserved tags), and you can add, modify, or delete tags.

    Important

    • Do not disable tags. If you disable tags, your EC2 instances might not be managed in accordance with your organization's policies.

    • For backups from Commvault Platform Release 2022E (11.28) and previous releases, if you add new tags to the restored EC2 instances, the previous tags are removed.

  9. Click Next.

    The Restore Options page appears.

Specify Settings for the Restore Operation

  1. Specify the following settings:

    • Power on VMs after restore: Select this setting to have the Commvault software start the EC2 instances after they are restored.

      The power state of the EC2 instances does not affect subsequent backups. If the EC2 instances are powered on during backups, by default, the EC2 instances are powered on again after the restore completes (unless you clear this check box).

    • Unconditionally overwrite if it already exists: If an EC2 instance that you are restoring and an EC2 instance in the destination AWS account have the same instance ID, select this setting have the software delete the instance in the destination AWS account and replace it with the EC2 instance that you are restoring.

      Note

      If an EC2 instance that you are restoring and an EC2 instance in the destination AWS account have the same instance ID, and you do not select Unconditionally overwrite if it already exists, the restore fails.

    • Reuse existing VM client: If an EC2 instance that you are restoring and an EC2 instance in the destination AWS account have the same instance ID, select this setting have the software reuse the EC2 instance in the destination AWS account and map its information (such as client name, host name, and client ID) to the source EC2 instance.

    • Notify user on job completion: Select this setting have the software send an email notification that the restore is complete.

      For the software to send an email notification, you must configure an email server.

    • Under Additional options, for Transport mode, select the mode to use for the restore:

      • Automatic (default): This option selects a mode as follows:

      • Amazon EBS Direct

      • AWS VM Import/Export

        With the AWS VM Import/Export mode, the software creates an Amazon S3 bucket in the destination AWS account to stage VHDX copies of each volume. The VHDX copies of the volumes are used by the AWS VM Import/Export service to re-create the EC2 instances. The S3 staging bucket is named gx-restore-region_name-account_id, where region_name is the name of the destination AWS Region and account_id is the ID of the destination AWS account for the restored EC2 instances.

      • Commvault HotAdd

        If you select Commvault HotAdd, you must either enter the guest credentials or have the drivers pre-installed on the EC2 instances.

      If you use either the Amazon EBS Direct mode or the Commvault HotAdd mode, you can restrict the scope of the auto-selected Amazon Machine Images (AMIs) that are used during the restore. For more information, see Enabling Specific AMI IDs for Restores and Replication.
