Backups for Google Cloud Platform

Updated

You can perform backups automatically based on the configuration for a hypervisor or VM group, or manually for a VM group or a specific instance.

The first backup of an instance is always a full backup. By default, all subsequent backups are incremental, capturing any changes to instance data since the last backup.

You can recover instance data, even when the most recent backup was incremental.

Backups run based on the following options:

  • Initial full backup: When you use Guided setup to set up the Virtualization solution, use the Back up now option to perform a backup for the default VM group.

  • Scheduled incremental backups: The server backup plan that is assigned to a VM group includes a schedule for ongoing incremental backups. Those backups are performed automatically based on the schedule, without requiring any user action.

  • Manual backups: You can perform on-demand backups for a VM group or for a specific instance.

If backups cannot start immediately, the backup jobs are queued.

You can configure a Google Cloud Platform (GCP) hypervisor to perform streaming or IntelliSnap backups. For more information, see IntelliSnap Support for Virtualization.

Note: If an instance fails to back up during an IntelliSnap backup of a VM group, the backup job is marked as completed with errors.

What Gets Backed Up

  • Instances (powered on or powered off)

  • Configuration files for each instance

  • Instance disks

  • Regional persistent disks (standard and solid-state drive)

  • Instance disks that are encrypted at the software protection level with a customer-managed encryption key

    You can generate customer-managed encryption keys using the Google Cloud Key Management Service.

What Does Not Get Backed Up

  • Images

  • Instance disks that are encrypted with a customer-supplied encryption key

  • Instance disks that are encrypted at the Hardware Security Module (HSM) protection level with a customer-managed encryption key

  • Local solid-state drive (SSD) scratch disks

    When local SSD scratch disks reside on an instance with other supported disks, during the backup operation, the SSD scratch disks are skipped. The other disks are included in the backup.
