Whatb is Disaster Recovery (DR)?

RPO and RTO

Recovery point objective (RPO)

Recovery time objective (RTO)

RLO

Recovery Level Objective (RLO) defines the granularity with which data has to be rocovered. Whether recovery is required for the whole instance, database or set of databases or specific tables. It is difficult to suddenly restore a heavily damaged system to 100%. When disaster occurs, restoring production like environment might not be possible. Therefore, RLO will be set depending on requirements and recovery scope.

RLO for Solution The solution architecture will use “Auto-failover group” for Azure SQL Managed Instance and manual failover for Azure Storage Account. “Auto-failover group” and failover feature ensure availability during region failure.
