Compute Engine インスタンスを、インスタンスとは異なるプロジェクトにある Backup Vault にバックアップする場合は、Backup Vault の Backup and DR Vault サービス エージェントに、そのプロジェクト内のインスタンスにアクセスする権限が付与されていることを確認します。(Backup Vault とインスタンスが同じプロジェクトにある場合、この権限はデフォルトですでに付与されています)。
Backup and DR Vault サービス エージェントに Compute Engine インスタンスを Backup Vault にバックアップするために必要な権限が付与されるようにするには、Compute Engine インスタンスのプロジェクトに対する Backup and DR Compute Engine オペレーター (roles/backupdr.computeEngineOperator)IAM ロールを Backup and DR Vault サービス エージェントに付与するよう管理者に依頼します。

You can change your instance's\nbackup plan to align your data protection strategy with your changing\noperational requirements.\n\nBackup and DR backup plans let you define advanced backup strategies\nto store your Compute Engine instances in secure storage locations\ncalled backup vaults. Using the backup plan applied to your instance,\nyou can create scheduled or on-demand backups of your instance in a\nbackup vault.\n\nBefore you begin\n\n- Enable the Backup and DR Service API where the Compute Engine instances are located.\n [Enable the API](https://console.cloud.google.com/flows/enableapi?apiid=backupdr.googleapis.com&_ga=2.145630134.30427899.1640890668-1982243420.1634228058)\n\n- [Create a backup vault](/backup-disaster-recovery/docs/cloud-console/backup-vault-create)\n- [Create a backup plan](/backup-disaster-recovery/docs/cloud-console/backup-plan-create)\n- Set up Log Analytics on your bucket to monitor Backup and DR backup jobs.\n\nRequired roles\n\n-\n\n To get the permissions that\n you need to edit an instance's properties and change the associated\n backup plan,\n\n ask your administrator to grant you the\n following IAM roles:\n\n - To edit the instance: [Compute Instance Admin (v1)](/iam/docs/roles-permissions/compute#compute.instanceAdmin.v1) (`roles/compute.instanceAdmin.v1`) on the project for the Compute Engine instance\n - To configure scheduled backups or run on-demand backups:\n - [Backup and DR Backup User](/iam/docs/roles-permissions/backupdr#backupdr.backupUser) (`roles/backupdr.backupUser`) on the project for the backup vault\n - [Viewer](/iam/docs/roles-overview#basic) (`roles/viewer`) on the project for the backup vault\n\n\n For more information about granting roles, see [Manage access to projects, folders, and organizations](/iam/docs/granting-changing-revoking-access).\n\n\n You might also be able to get\n the required permissions through [custom\n roles](/iam/docs/creating-custom-roles) or other [predefined\n roles](/iam/docs/roles-overview#predefined).\n- If you want to back up a Compute Engine instance to a\n backup vault that is in a different project than the instance, then\n make sure the\n [Backup and DR Vault Service Agent](/iam/docs/service-agents#backup-and-dr-vault-service-agent) for the backup vault has been\n granted permission to access the instances in that project. (If the\n backup vault and instance are in the same project, then this\n permission is already granted by default.)\n\n-\n\n To ensure that Backup and DR Vault Service Agent has the necessary\n permissions to back up a Compute Engine instance to a\n backup vault,\n\n ask your administrator to grant Backup and DR Vault Service Agent the\n\n\n [Backup and DR Compute Engine Operator](/iam/docs/roles-permissions/backupdr#backupdr.computeEngineOperator) (`roles/backupdr.computeEngineOperator`)\n IAM role on the project for the Compute Engine instance.\n\n\n | **Important:** You must grant this role to Backup and DR Vault Service Agent, *not* to your user account. Failure to grant the role to the correct principal might result in permission errors.\n\n \u003cbr /\u003e\n\nChange the backup plan applied to your instance\n\nYour new backup plan must be from the same project and store the backup in the\nsame backup vault as your existing plan.\n\nYou can change your instance's backup plan by modifying the instance\nconfiguration on the Google Cloud console, as follows:\n\n1. In the Google Cloud console, go to the **VM instances** page.\n\n [Go to VM instances](https://console.cloud.google.com/compute/instances)\n2. Click the name of the instance whose backup plan you want to change.\n The instance details page appears for the selected instance.\n\n3. Click edit **Edit** .\n The **Edit** page appears for your instance.\n\n4. Navigate to the **Backup plan** section and then click **Change plan**.\n\n5. In the **Select a backup plan** pane that appears, do the following:\n\n 1. In the **Backup plan name** column, click the name of the back plan that you want to use.\n 2. To confirm your choice of backup plan and return to the **Edit** page, click **Apply**.\n6. To apply your backup plan and save your new instance configuration,\n click **Save**.\n\nWhat's next\n\n- Learn how to use your instance's backup plan to [schedule or create backups in a backup vault](/backup-disaster-recovery/docs/cloud-console/compute/compute-instance-backup).\n- Learn how to [restore an instance from a backup vault](/backup-disaster-recovery/docs/cloud-console/compute/compute-instance-restore)."]]
