C. 6
Explanation
Geo-Zone-Redundant Storage (GZRS) in Microsoft Azure stores a total of 6 data copies to ensure high availability and durability for your critical data. This storage redundancy option combines the benefits of Zone-Redundant Storage (ZRS) and Geo-Redundant Storage (GRS) to provide comprehensive protection against various failure scenarios.
Here’s how the 6 data copies are distributed in GZRS:
Three synchronous data copies are stored across three separate availability zones within the primary region.
2. Three asynchronous data copies are replicated to a secondary region, with each copy stored in a different availability zone.
The synchronous replication within the primary region ensures that data is always consistent across the three copies. In the event of a failure in one or two zones, Azure can quickly failover to the remaining copy, minimizing downtime and data loss.
The asynchronous replication to the secondary region protects against regional outages. If the entire primary region becomes unavailable, Azure can failover to the secondary region, ensuring that your data remains accessible.
By leveraging GZRS, you can achieve a 99.99999999999% (12 9’s) durability for your Azure Storage accounts, providing the highest level of protection for your data. This makes GZRS an ideal choice for mission-critical workloads that require both high availability and strong disaster recovery capabilities.
In summary, Geo-Zone-Redundant Storage (GZRS) in Microsoft Azure stores 6 data copies – 3 synchronous copies in the primary region and 3 asynchronous copies in the secondary region – to deliver the ultimate combination of high availability, durability, and disaster recovery for your critical data.
