Cross-Region Key Vault Disaster Recovery

A cross-region restore verifies that your backup strategy can survive a regional outage and that your data remains intact across geographies. The process begins by deploying a new Key Vault in the target region using an ARM template. After the vault is created, you run the restore operation against the backup files that were stored in a secure, accessible location. Once the restore completes, you must reapply all of the vault's configuration settings in the new region, including access policies, private endpoints, encryption settings, and the soft-delete and purge protection flags. This step is critical because the backup file contains only the vault objects, not the vault's configuration. After reconfiguring the vault, you perform a test retrieval of secrets and certificates to confirm that the restored objects are functional and that the new vault is properly secured. A successful cross-region restore demonstrates that your backup artifacts can be recovered in a different geography under a separate resource group, satisfying disaster recovery and data residency requirements.
