  • Enhancing GKE data protection with cross-project backup and restore

As Google Kubernetes Engine (GKE) deployments grow and scale, adopting a multi-project strategy in Google Cloud becomes a best practice for security and environment organization. Creating clear boundaries by using distinct projects for development, testing, and production environments provides isolation and helps manage access control.

However, isolation introduces a data protection challenge: How do you effectively manage backups across these project boundaries? Without a native solution, centralizing backups, ensuring a clear separation of duties with IAM, and enabling robust disaster recovery all become  complex tasks, often forcing teams to rely on custom scripts or inefficient manual processes.

Introducing cross-project backup and restore

To address this, Backup for GKE, now in preview, supports cross-project backup and restore. This new capability allows you to back up workloads from a GKE cluster in one Google Cloud project, securely store the backups in a second, and restore them to a cluster in a third. This streamlines data protection, enhances your security posture, and offers greater flexibility for your operational workflows.Storing backups in a separate, isolated project and region is essential for modern disaster recovery, safeguarding your recovery capability during a regional outage or a compromise in a primary Google Cloud project — the foundation of a resilient infrastructure. This separation also simplifies regulatory compliance, boosts security by limiting the blast radius of any potential incident, and helps you meet RTO/RPO objectives.

Key benefits of cross-project backup and restore 

  • Centralized backup management: Consolidate GKE backups from multiple Google Cloud projects into a single project by pointing the backup plan for each cluster to the chosen backup project. This simple configuration provides your team with one control plane to oversee monitoring and manage backup policies.

  • Enhanced disaster recovery: Storing GKE backups in a separate project and region provides a vital layer of isolation, boosting your resilience against events like regional outages. If your source region becomes unavailable, you can create a restore plan from your backup project to recover your workloads to a cluster in another project.

  • Streamline operations: seeding, cloning, and collaboration

    Cross-project capabilities bring agility to your development lifecycle by simplifying how you copy data between environments. You can now leverage production backup data for testing or rapidly clone entire application environments.

    • Seed and clone environments: You can populate a staging environment with data from a prior backup or create a sandbox. Create a restore plan using an existing backup plan located in the backup project, then select a backup — such as one from production for seeding or a dev environment for cloning — and target a cluster in any other project as your destination. This lets you create test environments and isolated sandboxes.

    • Simplify cross-team collaboration: Since all backups are stored in a central backup project, you can grant a developer from another team a role like Delegated Restore Admin, and also provide them with read permission on the specific backup plan and all of its associated backups. They can then use it to restore to their cluster without needing access to the other team’s live source project.

  • Achieve separation of duties for security and compliance

    Isolating backups in a dedicated project allows you to enforce the principle of least privilege by assigning distinct responsibilities. You can empower your application teams with self-service permissions to back up and restore applications within their own projects, without giving them control over the central backup repository. A central platform or operations team can be granted administrative control over the backup project to govern the entire data lifecycle — from setting retention policies with immutability to conducting audits, all without needing access to live production environments. This separation is key to reducing risk and simplifying audits.
