Restore a VM from a snapshot

This page describes how to restore a virtual machine (VM) disk from an image disk snapshot that was created through Google Distributed Cloud (GDC) air-gapped backup and restore procedures.

Before you begin

To restore a VM disk from a snapshot, you must have the following:

  • An existing snapshot. For more information, see Back up disks.

  • The necessary identity and access roles:

    • Project VirtualMachine Admin: manages VMs in the project namespace. Ask your Project IAM Admin to grant you the Project VirtualMachine Admin (project-vm-admin) role.
    • Backup Creator: creates manual backups and restores. Ask your Project IAM Admin to grant you the Backup Creator (backup-creator) role.
    • Project Viewer: has read-only access to all resources within project namespaces. Ask your Project IAM Admin to grant you the Project Viewer (project-viewer) role.

Restore a snapshot

Create a new VM from a disk snapshot by using the GDC console or the application programming interface (API).

Console

  1. Sign in to the GDC console.
  2. In the navigation menu, click Virtual Machines > Snapshots.
  3. Select a project.
  4. In the list of snapshots, find the snapshot to restore and click Restore.
  5. In the New disk name field, enter the name of the disk to restore the backup in.
  6. Enter a Restore name for the restore.
  7. Click Restore.

API

Create a VirtualMachineRestoreRequest custom resource to initiate the restore process.

The restoration of application capability is subject to the VM operating system or image. Create a VirtualMachineRestoreRequest custom resource to initiate the restore process:

apiVersion: virtualmachine.gdc.goog/v1
kind: VirtualMachineRestoreRequest
metadata:
  name: RESTORE_REQUEST_NAME
  namespace: PROJECT_NAME
spec:
  virtualMachineBackup: VM_BACKUP_NAME
  restoreName: RESTORE_NAME
  restoredResourceName: RESTORE_PREFIX
  restoredResourceDescription: RESTORED_RESOURCE_DESCRIPTION

Replace the following:

  • VM_BACKUP_NAME: the name of the VirtualMachineBackup resource to restore from.
  • PROJECT_NAME: the name of the GDC project.
  • RESTORE_REQUEST_NAME: the name of the restore request that is being initiated.
  • RESTORE_NAME: the name to give the restore that is being initiated.
  • RESTORE_PREFIX: a prefix that is appended to the start of the name for backups that this request restores.
  • RESTORED_RESOURCE_DESCRIPTION: description of why the restore is performed.

The result of the restore creates a new disk with the same configuration and disk state as the snapshot, completing the data backup and recovery process.
