Control: Azure > CIS v4.0 > 10 - Storage Services > 10.03 - Storage Accounts > 10.03.12 - Ensure Redundancy is set to 'geo-redundant storage (GRS)' on critical Azure Storage Accounts

Configures auditing against a CIS Benchmark item.

Level: 2

Geo-redundant storage (GRS) in Azure replicates data three times within the primary region using locally redundant storage (LRS) and asynchronously copies it to a secondary region hundreds of miles away. This setup ensures high availability and resilience by providing 16 nines (99.99999999999999%) durability over a year, safeguarding data against regional outages.

Enabling GRS protects critical data from regional failures by maintaining a copy in a geographically separate location. This significantly reduces the risk of data loss, supports business continuity, and meets high availability requirements for disaster recovery.
