Simple BCDR solution |
Using Site Recovery, you can set up and manage replication, failover, and failback from a single location in the Azure portal. |
VMware VM replication |
You can replicate VMware VMs to Azure using the improved Azure Site Recovery replication appliance that offers better security and resilience than the configuration server. For more information, see Disaster recovery of VMware VMs. |
On-premises VM replication |
You can replicate on-premises VMs and physical servers to Azure. Replication to Azure eliminates the cost and complexity of maintaining a secondary datacenter. |
Workload replication |
Replicate any workload running on supported Azure VMs, on-premises Hyper-V and VMware VMs, and Windows/Linux physical servers. |
Data resilience |
Site Recovery orchestrates replication without intercepting application data. When you replicate to Azure, data is stored in Azure storage, with the resilience that provides. When failover occurs, Azure VMs are created based on the replicated data. This also applies to Extended Zones to Azure region Azure Site Recovery scenario. |
RTO and RPO targets |
Keep recovery time objectives (RTO) and recovery point objectives (RPO) within organizational limits. Site Recovery provides continuous replication for Azure VMs and VMware VMs, and replication frequency as low as 30 seconds for Hyper-V. You can reduce RTO further by integrating with Azure Traffic Manager. |
Keep apps consistent over failover |
You can replicate using recovery points with application-consistent snapshots. These snapshots capture disk data, all data in memory, and all transactions in process. |
Testing without disruption |
You can easily run disaster recovery drills, without affecting ongoing replication. |
Flexible failovers |
You can run planned failovers for expected outages with zero-data loss. Or, unplanned failovers with minimal data loss, depending on replication frequency, for unexpected disasters. You can easily fail back to your primary site when it's available again. |
Customized recovery plans |
Using recovery plans, you can customize and sequence the failover and recovery of multi-tier applications running on multiple VMs. You group machines together in a recovery plan, and optionally add scripts and manual actions. Recovery plans can be integrated with Azure Automation runbooks. Note: This functionality is currently supported for Region-to-Region replication and will be available on Azure Extended Zones soon. |
BCDR integration |
Site Recovery integrates with other BCDR technologies. For example, you can use Site Recovery to protect the SQL Server backend of corporate workloads, with native support for SQL Server Always On, to manage the failover of availability groups. |
Azure automation integration |
A rich Azure Automation library provides production-ready, application-specific scripts that can be downloaded and integrated with Site Recovery. |
Network integration |
Site Recovery integrates with Azure for application network management. For example, to reserve IP addresses, configure load-balancers, and use Azure Traffic Manager for efficient network switchovers. |
Shared disk (preview) |
You can protect, monitor, failover, and re-protect your workloads running on Windows Server Failover Clusters (WSFC) on Azure VMs using shared disk. You can use shared disks for your critical applications such as SQL FCI, SAP ASCS, Scale-out File Servers, etc., while ensuring business continuity and disaster recovery with Azure Site Recovery. |
