Cloud Backup and Disaster Recovery Services
Make sure every critical system and data set can be recovered, from an accidental deletion to a ransomware attack or a full regional outage, within the time your business can tolerate.
Recovery Is the Only Backup Metric That Matters
Most organizations have backups. Far fewer know whether they can actually restore a complete, working application within a defined time, or whether those backups would survive an attacker who has gained administrative access. Ransomware groups now routinely target backup systems first, and cloud outages, while rare, can affect an entire region. The question is no longer whether data is copied, but how quickly and confidently the business can resume after something goes wrong.
Hanoi Technology designs backup and disaster recovery around your business requirements. We work with system owners to define recovery time objectives (RTO) and recovery point objectives (RPO), then implement the right strategy for each workload, from backup and restore to pilot light, warm standby and multi-site active-active. Backups are immutable and isolated, recovery is automated where possible, and plans are tested regularly so you know they work.
The Challenge
Gaps We Find in Backup and DR Plans
Weaknesses that typically surface only during a real incident.
Backups Without Tested Restores
Backup jobs report success, but restores are rarely exercised. When needed, teams discover missing dependencies, corrupted copies or undocumented steps that add days to recovery.
Backups Exposed to Ransomware
Backups stored in the same account, with the same credentials as production, can be encrypted or deleted by an attacker who compromises an administrator.
Undefined Recovery Objectives
Without agreed RTO and RPO targets per system, DR investment is either excessive for minor systems or insufficient for critical ones.
Outdated and Manual Runbooks
Recovery procedures written years ago no longer match the environment. Manual steps performed under pressure lead to errors and delays.
Business Value
What Resilient Backup and DR Gives You
Confidence in Recovery
Regular, documented recovery tests prove that systems can be restored within their targets.
Protection Against Ransomware
Immutable, logically isolated backups mean an attacker cannot destroy your last line of defense.
Right-Sized Investment
Recovery strategies matched to each system’s criticality avoid overspending on low-priority workloads.
Reduced Downtime
Automated failover and recovery orchestration shorten outages from days to hours or minutes for critical systems.
Compliance and Audit Readiness
Retention policies, encryption and test evidence support regulatory and customer requirements for data protection and continuity.
Lower Cost Than a Second Data Center
Cloud DR uses on-demand capacity, so you pay mainly for storage and minimal standby resources until a disaster occurs.
An Untested Recovery Plan Is Only a Hope
Systems change every week, and every change can break a recovery path. Scheduled restore tests and DR exercises are the only way to know that your plan still works, and they consistently reveal issues that are far cheaper to fix in advance.

Use Cases
Backup and DR Scenarios
Common situations where clients ask for our help.
Ransomware Recovery Readiness
A company worried about ransomware moves backups into an isolated, immutable vault. A recovery exercise proves core systems can be restored in a clean environment.
On-Premises DR to the Cloud
An organization replaces its secondary data center with cloud-based disaster recovery. Servers replicate continuously and can be launched in the cloud when needed.
Multi-Region Failover for a Critical Service
A customer-facing platform must survive a regional outage. A warm standby in a second region is maintained and failover is rehearsed regularly.
Database Point-in-Time Recovery
A transactional system needs protection against accidental deletion and corruption. Continuous backups allow restore to any point within the retention window.
Microsoft 365 and SaaS Backup
Email, files and collaboration data in SaaS applications are backed up independently, so deleted or encrypted data can be recovered beyond native retention.
Kubernetes Backup and Restore
Containerized applications and persistent volumes are backed up with their configuration, allowing whole clusters to be rebuilt quickly.

Cloud Backup and Disaster Recovery FAQ
What are RTO and RPO?
Recovery time objective (RTO) is the maximum acceptable time a system can be unavailable after an incident. Recovery point objective (RPO) is the maximum acceptable amount of data loss, measured in time, for example the last fifteen minutes of transactions. Together they define how quickly and how completely a system must be recovered, and they drive the choice of backup frequency, replication and DR strategy for each workload.
Which disaster recovery strategy do we need?
It depends on each system’s RTO, RPO and budget. Backup and restore is the lowest cost but slowest to recover. Pilot light keeps core components such as databases replicated, with other resources started on demand. Warm standby runs a scaled-down copy that can be scaled up quickly. Multi-site active-active runs full capacity in multiple locations for near-zero downtime. Most organizations use different strategies for different tiers of systems.
How do you protect backups from ransomware?
We use several layers. Backups are stored with immutability features such as object lock or immutable vaults, so they cannot be altered or deleted during the retention period. Copies are kept in a separate account or subscription with independent credentials and restricted access. We monitor for unusual deletion or encryption activity and regularly test restores into isolated environments to confirm that clean recovery is possible.
How often should we test disaster recovery?
Critical systems should have recovery tested at least annually through a full exercise, with more frequent automated restore tests of individual backups, ideally monthly or quarterly. Tests should also follow major architecture changes. We tailor the schedule to your risk profile and regulatory requirements, document each test against RTO and RPO targets, and track remediation of any issues found.
Do SaaS applications like Microsoft 365 need separate backup?
SaaS providers maintain availability of their service, but under their shared responsibility models, protecting your data against accidental deletion, malicious actions or ransomware is largely your responsibility. Native retention and recycle bins have limits. An independent backup of Microsoft 365, Google Workspace, Salesforce or other critical SaaS data gives you longer retention, granular restore and protection that does not depend on the same account.
How much does cloud disaster recovery cost?
Cost depends mainly on the chosen strategies, the volume of data protected, retention periods and how much standby infrastructure runs continuously. Backup and restore and pilot light approaches are typically much cheaper than maintaining a secondary data center, because compute is only provisioned during a disaster or test. We model costs per tier during design so you can balance resilience against budget transparently.
