Azure Storage comes with a number of replication options. We will mention the following three:
- LRS - locally redundant storage: This is the minimal replication type, which provides three storage replicas in the same region. This handles the storage high availability.
- GRS - geo redundant storage: This type provides three replicas in the same region, and additional three replicas in a secondary region. This handles disaster recovery.
- RA-GRS - read-access geo redundant storage: This type is similar to GRS, with the secondary replicas available for read access. This handles disaster recovery, and allows additional usage of the replicas during normal operation.
For Storage disaster recovery planning, either GRS or RA-GRS replication ...
