Because Compute Engine performs local caching in\ntarget zones, disk creation from images is faster than disk creation from\nsnapshots.\n\n### Use machine images to create backups of all disks attached to an instance\n\nTo create backups of all disks that are attached to an instance,\n[use machine images](/compute/docs/machine-images/create-machine-images#create-image-from-instance).\nA machine image can be used to backup multiple disks at a time to help ensure\nthat the data captured in the machine image is consistent across all disks. A\npersistent disk snapshot can only backup a single disk at a time. For more\ninformation, see [When to use machine images](/compute/docs/machine-images#when-to-use).\n\n### Use Google Cloud Backup and DR Service to manage instance backups at scale\n\nWith Backup and DR Service, you manage backups of your instances across projects and\nenvironments by using advanced policies, centralized monitoring and backup\nreporting in the following way:\n\n- [Create backup vaults](/backup-disaster-recovery/docs/cloud-console/backup-vault-create) that serve as secure storage locations for your backups.\n- [Create backup plans](/backup-disaster-recovery/docs/cloud-console/backup-plan-create) to configure the schedule and rules for your backup.\n- Apply backup plans [to existing instances](/backup-disaster-recovery/docs/cloud-console/compute/compute-instance-backup) or [during instance creation](/compute/docs/instances/create-instance-with-gcbdr-backup-plan).\n- Assign specific permissions for [backup access](/backup-disaster-recovery/docs/configuration/workforce-identity-federation).\n- Proactively and reactively [monitor backup jobs](/backup-disaster-recovery/docs/monitor-reports/monitor-jobs-console).\n- Create [reports for tracking backups](/backup-disaster-recovery/docs/monitor-reports/reports-overview) across resources spanning multiple projects.\n- When needed, [restore an instance from a backup vault](/backup-disaster-recovery/docs/cloud-console/compute/compute-instance-restore).\n\nYou can also integrate\n[Security Command Center](/security-command-center/docs/security-command-center-overview)\nwith Backup and DR Service to additionally:\n\n- Track audit logs for backup access.\n- Monitor for malicious activity on your backups.\n\nWhat's next\n-----------\n\n- Read [Best practices for persistent disk snapshots](/compute/docs/disks/snapshot-best-practices)."]]
