-- To guarantee low latency, the snapshot of your backup is stored in Azure Blob storage in the same region as the current write region (or **one** of the write regions, in case you have a multi-region write configuration). For resiliency against regional disaster, each snapshot of the backup data in Azure Blob storage is again replicated to another region through geo-redundant storage (GRS). The region to which the backup is replicated is based on your source region and the regional pair associated with the source region.
