Azure Backup and Disaster Recovery Services
Design, implement and regularly test backup and disaster recovery on Azure, so you can recover from outages, mistakes and ransomware within the time your business can tolerate.
Be Ready to Recover, Not Just Ready to Back Up
Having backups is not the same as being able to recover. Many organizations discover during an incident that a database was excluded from policy, that restores take far longer than expected, or that attackers deleted backups along with production data. On Azure, Azure Backup, Azure Site Recovery, zone-redundant services and the Resiliency experience in the Azure portal, which extends the earlier Azure Business Continuity Center, provide the building blocks. They need to be combined deliberately around clear recovery objectives.
Hanoi Technology defines recovery point and recovery time objectives with your business owners, maps them to the right Azure capabilities for each workload, and proves them through scheduled recovery drills. The result is documented, tested resilience rather than assumptions.
The Challenge
Backup and DR Gaps We Commonly Find
Resilience gaps stay invisible until the day they matter.
Unclear Recovery Objectives
Without agreed RPO and RTO per application, teams either overprotect everything at high cost or underprotect critical systems.
Backups Exposed to Ransomware
Backups accessible with the same credentials as production can be deleted or encrypted by attackers who compromise an administrator account.
Untested Recovery Plans
DR runbooks written years ago reference servers and IP addresses that no longer exist, and failovers have never been rehearsed end to end.
Inconsistent Coverage
New VMs, databases and storage accounts are deployed without backup policies, leaving gaps that only appear in an audit or an outage.
Business Value
What Resilient Azure Workloads Deliver
Recovery Objectives You Can Prove
Each critical workload has defined RPO and RTO targets and drill results that show they can be met.
Protection Against Ransomware
Immutable vaults, soft delete, multi-user authorization and private endpoints make backups much harder to tamper with or destroy.
Faster Regional Failover
Azure Site Recovery replicates VMs to another region, with recovery plans that sequence application tiers and run scripts during failover.
Complete, Enforced Coverage
Azure Policy automatically applies backup policies to new resources, and the Resiliency experience shows protection status across the estate.
Resilience Is Proven Only by Recovery
A recovery plan that has never been executed is a hypothesis. We schedule regular test failovers and restores, record actual recovery times and use the results to improve plans before a real incident tests them.

We implement backup policies, replication, recovery plans and vault hardening as code, enforced with Azure Policy.
Deliverables: Implemented protection · Policy assignments
- 04
Test Recovery
We run test failovers and restores in isolated networks, measure recovery times and fix issues found.
Deliverables: Drill reports · Remediation actions
- 05
Operate and Review
Monitoring, alerts and periodic drills keep protection aligned with the changing estate.
Deliverables: Operational runbooks · Review schedule
Use Cases
Azure Backup and DR Use Cases
Scenarios we design and test for.
Regional Outage Readiness
A customer-facing application replicates to a paired or alternate region, with a recovery plan that brings up databases, application servers and web tiers in order.
On-Premises to Azure DR
VMware servers in a single data center replicate to Azure with Site Recovery, replacing an expensive secondary site.
Ransomware Recovery Drill
A company restores critical systems from immutable backups into an isolated environment to validate a clean recovery path.
SQL Server Point-in-Time Restore
Databases running in Azure VMs use Azure Backup with frequent log backups, enabling restores to a specific point after an accidental deletion.
Long-Term Retention for Compliance
Financial records are retained for years in vaults with archive tier for older recovery points to control cost.
AKS Workload Protection
Kubernetes namespaces and persistent volumes are backed up with Azure Backup for AKS, enabling cluster recovery or migration.

Azure Backup and Disaster Recovery FAQ
What is the difference between Azure Backup and Azure Site Recovery?
Azure Backup creates point-in-time copies of data and systems that you restore from after deletion, corruption or ransomware. Azure Site Recovery continuously replicates virtual machines to another region or from on-premises to Azure, so you can fail over whole applications quickly during an outage. Most critical workloads need both: Site Recovery for fast failover and Backup for recovering clean data from earlier points in time.
How do you protect backups from ransomware?
We separate backup administration from production administration and apply several layers: immutable vaults so recovery points cannot be deleted before retention expires, soft delete for accidental or malicious deletion, multi-user authorization through Resource Guard for critical operations, private endpoints and customer-managed keys. We also define a recovery process that restores into an isolated environment and checks systems before reconnecting them.
How often should we test disaster recovery?
Critical applications should be tested at least once or twice a year, and after any significant architecture change. Azure Site Recovery supports test failovers into isolated networks without affecting production replication, which makes regular drills practical. Backup restores should be tested more frequently for a sample of workloads. We record measured recovery times and compare them with your objectives after each drill.
What does backup and DR cost on Azure?
Azure Backup charges per protected instance plus storage consumed, which depends on data size, change rate, retention and redundancy option. Site Recovery charges per protected instance plus replicated storage, with compute charged only during failover or testing. We model costs per protection tier so that critical workloads get strong protection while less important systems use cheaper policies.
Can you protect on-premises servers as well?
Yes. Azure Site Recovery can replicate VMware, Hyper-V and physical servers to Azure for disaster recovery, and Azure Backup can protect on-premises workloads through the MARS agent or Microsoft Azure Backup Server. This lets organizations replace a secondary data center with Azure while keeping production on-premises, or protect hybrid estates during a gradual migration.
How do you handle PaaS services like Azure SQL or Cosmos DB?
PaaS services have their own resilience features, which are usually more effective than VM-level backups. Azure SQL offers automated backups, long-term retention, geo-replication and failover groups. Cosmos DB supports multi-region writes and continuous backup. Storage offers zone and geo redundancy. We design these features into the application architecture and include them in recovery plans and drills.
