Zone-redundant storage (ZRS) replicates your data synchronously across three storage clusters in a single region. Each storage cluster is physically separated from the others and is located in its own availability zone (AZ). Each availability zone—and the ZRS cluster within it—is autonomous and includes separate utilities and networking features.
When you store your data in a storage account using ZRS replication, you can continue to access and manage your data if an availability zone becomes unavailable. ZRS provides excellent performance and low latency. ZRS offers the same scalability targets as locally redundant storage (LRS).
Consider ZRS for scenarios that require consistency, durability, and high availability. Even if an outage or natural disaster renders an availability zone unavailable, ZRS offers durability for storage objects of at least 99.9999999999% (12 9's) over a given year.
