Previously, performing differential and transaction log restores on Amazon RDS SQL Server instances required converting Multi-AZ or read replica configurations to Single-AZ, causing operational delays and downtime. The update enables these restores directly on instances configured with Multi-AZ and read replicas within the same region, preserving continuous availability and read workloads.
This improvement facilitates faster disaster recovery and database migration workflows by applying incremental data changes alongside full backups on resilient architectures. While the service vendor describes these benefits, independent performance analyses or metrics were not presented in source materials.
