- Cloud SQL for SQL Server
Cloud SQL for SQL Server now supports significantly faster re-encryption of instances and replicas protected by customer-managed encryption keys (CMEKs), and re-encryption now completes with zero downtime. The steps to re-encrypt your instances and replicas are unchanged, but the operation now re-encrypts the underlying disks in-place, without creating re-encryption backups. For more information, see Re-encrypt an existing CMEK-enabled instance or replica .
