Azure Disaster Recovery as a Service — DRaaS

Azure Disaster Recovery as a Service is the Azure-specific implementation of DRaaS — built around Azure Site Recovery (ASR), Azure Backup, geo-redundant storage, and the Azure region-pair model. This page is deliberately distinct from our cross-cloud DR service at disaster recovery service provider, which orchestrates DR across AWS, Azure, GCP, and on-premises estates with vendor-neutral tooling. If your workloads run on Azure and you want native ASR plus Azure Backup operated for you, this is the right page. If you need DR across multiple clouds or want an alternative to ASR — for example, Zerto, Veeam, or Commvault — start with the cross-cloud sibling instead. Most disaster recovery plans are written once, filed away, and never tested. When an actual disaster strikes — datacenter failure, ransomware encryption, or an Azure regional outage — organisations discover that their replication was misconfigured, their recovery procedures are outdated, and their actual RTO is 10x longer than documented. The cost of this discovery is catastrophic: extended downtime averaging $5,600 per minute for enterprise systems, data loss, regulatory penalties under NIS2 and DORA, and customer trust that takes years to rebuild. The 2025 disaster-recovery research summarised in our cloud DR business case shows that organisations with quarterly-tested DR plans recover up to 8x faster from major incidents than those that rely on documentation alone.

Opsio's Azure DRaaS eliminates the gap between documented plans and actual capability. We deploy Azure Site Recovery for continuous replication of VMs, databases, and application tiers to a paired secondary Azure region — Sweden Central to West Europe, North Europe to West Europe, West US 2 to West Central US, or whichever Microsoft-defined region pair matches your data-residency obligations. Recovery plans are automated with sequenced failover steps, pre- and post-scripts that handle DNS updates and load-balancer reconfiguration, and manual approval gates for irreversible decisions. Most importantly, we test failover quarterly — actually executing the recovery plan in an isolated network sandbox to verify that applications come up correctly, data is consistent, dependency chains resolve, and recovery time meets your RTO targets. Test results are written up for compliance auditors and your business continuity steering committee, and the playbook is updated whenever the test reveals a gap.

Our DRaaS solution covers the full business continuity lifecycle: risk assessment and business impact analysis (BIA), RPO/RTO definition per application tier, replication architecture design, automated recovery plan implementation, regular testing, and ongoing monitoring of replication health under our broader Azure managed services umbrella. We support Azure-to-Azure DR, on-premises-to-Azure DR via the ASR Mobility Service agent, VMware-on-Azure DR with native vSphere replication into ASR, and hybrid scenarios coordinated through Azure migration service when DR is part of a broader move to Azure. Coverage extends to Azure SQL geo-replication, Cosmos DB multi-region writes, Azure Files cross-region snapshots, and the Azure Backup soft-delete and immutable-vault controls that defend against ransomware encryption of backups themselves. Every implementation is mapped to NIS2, DORA, and ISO 22301 business-continuity controls, with documented evidence packages suitable for regulator review and customer due-diligence questionnaires.
