To provide robust data protection against regional failures, ensure that geo-redundant storage (GRS) is enabled for your Microsoft Azure Storage accounts. Azure GRS replicates data three times within the primary region using Locally Redundant Storage (LRS) and asynchronously copies it to a secondary region. This methodology provides 16 nines (99.99999999999999%) annual durability, ensuring high availability and resilience against regional outages.
Once geo-redundant storage (GRS) is enabled, Microsoft Azure copies your data to a geographically separate location so that it is protected from transient hardware failures, network or power outages, and natural disasters. This significantly reduces the risk of data loss, supports business continuity, and meets high availability requirements for disaster recovery.
