Azure SQL Hyperscale Tier Now Offers New Storage Redundancy Options

In Azure SQL Hyperscale, the default backup storage is geo-replication to a paired region. However, due to regulatory, compliance or other specific business requirements related to data residency control, this has been a problem for some applications. The new storage redundancy options solve this by providing options that customers can choose from aside from geo-redundancy. These are zone redundancy and local redundancy.

  • Locally redundant storage (LRS): Your data is replicated three times within a single physical location. This protects against server rack and drive failures but will not help in the case of disasters like flooding or fire.
  • Zone-redundant storage (ZRS): Your data is replicated across three Azure availability zones within the primary region. As they are three separate locations, this provides further protection for your backups.
  • Geo-redundant storage (RA-GRS): Your data is replicated three times within the same location and also asynchronously to a separate location in a secondary region hundreds of miles away. Thus providing the highest level of protection for those not concerned by location.
