By default, all backups taken on Azure SQL Database are stored on read-access geo-redundant storage (RA-GRS) blobs that are being replicated in paired regions, ensuring data is protected in case of planned and unplanned events. Preview of configurable backup storage redundancy options for Azure SQL DB is coming soon to South East Asia, with additional regions expected in the coming months. This feature will provide you with more flexibility and choice to pick between locally redundant storage (LRS), zone redundant storage (ZRS) or geo redundant (RA-GRS) storage blobs for their backups.
As additional regions are launched in preview, there will be more backup storage redundancy options available to use to meet your data residency requirements or minimize backup costs. You will be able to easily configure backup storage redundancy in the Azure portal. For more information, visit our Tech Community blog.
