Geo Redundant Storage (GRS) is designed to protect against what?

Geo Redundant Storage (GRS) is specifically designed to provide durability and high availability by replicating data in multiple geographically separated locations. This means that in the event of a regional outage, where an entire datacenter or a specific geographical area may malfunction or become unavailable, GRS ensures that copies of the data still exist in another region. This approach enables organizations to safeguard their data against disasters that affect an entire geographic area, such as natural disasters, widespread technical failures, or regional power outages, thereby maintaining the access and integrity of the data.

GRS continuously monitors the health of the primary and secondary storage locations, allowing for seamless failover to the secondary region when needed. This capability is essential for disaster recovery and maintaining business continuity in scenarios where accessing data from the primary region is no longer possible. Thus, the design purpose of GRS inherently addresses challenges posed by regional outages.
