Google Cloud has introduced cross-region backups for its Backup and DR Service, giving customers more flexibility in how they protect data against regional outages while managing costs and regulatory requirements. The feature, now generally available, allows backups to be stored in regions that are completely distinct from the regions where primary workloads run.
The update builds on Google Cloud’s existing multi-region backup capabilities, which are designed to deliver high availability but can be more expensive than some customers need for every application. By decoupling backup destinations from source regions, organizations can choose specific secondary regions that align with their business continuity and data residency strategies. Google positions this decoupling as a way to protect against localized regional outages while retaining granular control over where data resides.
Cross-region backups are now fully available for Compute Engine instances, Disks and Filestore, with support for Cloud SQL and AlloyDB planned for a later date. Google presents the new option as a middle ground between single-region and multi-region setups, aimed at customers seeking resilience without always paying for near-zero downtime architectures. The company highlights three primary benefits: cost optimization, simplified compliance and improved regional resilience.
On cost, cross-region backups enable customers to selectively designate recovery regions instead of relying solely on predefined multi-region deployments. This more granular approach is intended to help organizations maximize value by aligning backup architectures with the criticality of individual applications. For compliance, the service allows customers to choose exactly which geopolitical boundary their backups should reside in, which Google notes can help navigate data residency laws such as the European Union’s GDPR.
From a resilience standpoint, the new feature is designed to protect against localized disasters by placing restorable copies of data in geographically separate regions. The operational flow remains integrated with existing Backup and DR workflows: users create a backup vault in a secondary region, configure a backup plan in the source region that targets this remote vault and then attach the plan to their resources. Once configured, Backup and DR automatically moves data directly into the regional backup vault outside the source region.
Google describes cross-region backups as a way to deliver a robust layer of protection without compromising on complex compliance and data residency standards. It also emphasizes that the capability offers more autonomy in selecting secondary locations compared with the predefined boundaries of multi-region deployments. The company is directing customers to its Backup and DR console and related documentation for guidance on creating vaults that support cross-region backups and understanding billing and inter-region data transfer charges.
