Google Cloud has announced the general availability of cross-region backups for its Backup and DR Service. Unlike multi-region backups, this feature lets organizations store backups in a completely different region from the primary workload, offering a cost-effective middle ground between same-region and multi-region strategies. It supports Compute Engine instances, Disks, and Filestore, with Cloud SQL and AlloyDB support coming later. Setup involves creating a backup vault in a secondary region, configuring a backup plan pointing to that vault, and attaching it to the resource. Key benefits include cost optimization, simplified compliance with data residency laws like GDPR, and improved resilience against regional outages.
