Hybrid Backup Recovery - HBR - Supports Zone-redundant Storage
Target customers: users who want to back up data. Features released: HBR allows you to create ZRS RDS instances in addition to locally redundant storage (LRS) RDS instances. A ZRS RDS instance uses the multi-zone deployment method to distribute data across three zones that belong to the same region. If one zone fails, you can still access the data that is stored in the other two zones.
