A simple way to picture Azure Site Recovery (Disaster Recovery)
A business has a disaster plan: what to do if the main office burns down. Azure Site Recovery enables disaster plans for applications: automatic failover to backup infrastructure.
Site Recovery automates failover of on-premises or Azure workloads to a secondary location during disasters, reducing RTO (recovery time) and RPO (recovery point).
Configure replication
Workloads replicate to a secondary location.
Test failover
Failover is tested without affecting production.
Failover
During a disaster, failover to the secondary happens automatically or manually.
A company replicates production VMs to Azure, automatically failing over if the on-premises data center fails.
Objective 2.1 expects understanding of disaster recovery automation.
Automates failover during disasters.
Reduces RTO and RPO.
Supports on-premises and Azure workloads.
It automates failover of workloads to a secondary location during disasters, reducing downtime and data loss.
