Types of Disaster Recovery Solutions
From ransomware to natural disasters, disruptive events can strike unexpectedly - threatening your ability to access critical data and keep essential services online. Disaster Recovery (DR) solutions come in various forms, each designed to help you restore operations and minimise downtime. In Australia, businesses often look to guidelines from the Australian Cyber Security Centre (ACSC) or consider the Essential Eight strategies to bolster resilience against both digital and physical threats. By choosing the right DR approach, you ensure your organisation can weather the worst disruptions - be it a flood in the data centre, a system-wide cyberattack, or smaller local outages.
This article explores types of disaster recovery solutions - from classic onsite backups to advanced cloud replication - highlighting how each fits different risk profiles, budgets, and compliance needs. We’ll also reference earlier discussions - like What Is Disaster Recovery? and Importance of Data Backups - to show how these solutions form part of a comprehensive continuity plan aligned with Australian best practices. Whether you’re a small firm on the Central Coast (NSW) or a national enterprise, understanding these DR approaches helps you pick strategies that keep downtime low and data safe.
1. Why Multiple DR Solutions Exist
Varied Risk Profiles
Organisations differ by industry, regulatory obligations, and tolerance for downtime or data loss. A high-availability financial service may require near-instant failover, while a small retailer might accept a few hours’ downtime.
Cost vs. Complexity
Real-time mirroring is typically pricier than weekly offline backups. Each solution balances budget constraints with desired Recovery Time Objective (RTO) and Recovery Point Objective (RPO).
Local Infrastructure vs. Cloud
Some Australian businesses prefer on-prem solutions for data residency reasons, while others embrace cloud-based DR for simpler scalability and reduced maintenance overhead.
Compliance and Regulatory Needs
Sectors like finance, healthcare, or government often have stricter DR requirements, influenced by APRA guidelines or local data privacy laws, which shapes the DR solutions chosen.
2. Classic Onsite DR Solutions
2.1 On-Premise Backup and Restore
What: Regular backups (full or incremental) to local drives, network-attached storage, or tape libraries stored onsite.
Pro: Straightforward to implement, quick restoration if only the server or data area is affected.
Con: Vulnerable to physical site disasters (fires, floods), theft, or ransomware that encrypts both production and backup locations.
2.2 Secondary Onsite DR Site
What: A second data centre or server room within the same facility or campus, hosting backup infrastructure.
Pro: Faster switch-over if the primary system fails, minimal data transit time.
Con: If the building experiences a catastrophic event (e.g., major flood), both sites could be compromised.
3. Offsite and Replication-Based DR Solutions
3.1 Offsite Backup (Physical Media)
What: Copying backups to tape or external drives, then sending them to secure offsite storage (like a vault or third-party facility).
Pro: Protects data from local disasters, ensures an offline copy safe from ransomware that targets network backups.
Con: Slower to retrieve if a major restore is needed; manual handling can introduce human error.
3.2 Real-Time Replication to a Secondary Site
What: Continuously mirroring production workloads to a geographically separate data centre.
Pro: Near-instant failover and minimal data loss (low RPO), suitable for mission-critical apps.
Con: Pricier due to duplicate hardware, network bandwidth for replication, plus maintenance of a secondary site.
4. Cloud-Based Disaster Recovery Solutions
4.1 Cloud Backup
What: Storing backups (file-level or image-level) in a cloud service (e.g., AWS S3, Azure Blob) on a regular schedule.
Pro: Offsite, scalable, minimal hardware management. Usually cost-effective for longer retention.
Con: Restores can be slower if large data volumes must be downloaded. Outage cost if relying solely on cloud for major restores.
4.2 Cloud Replication and Failover
What: Continuously replicating on-prem servers to a cloud environment. In a disaster, you “spin up” virtual machines in the cloud.
Pro: Rapid failover, near-real-time data, flexible resource scaling if your primary site is compromised.
Con: Higher ongoing costs for replication bandwidth and possibly “hot standby” fees.
4.3 Backup as a Service (BaaS)
What: Fully managed backup solutions from a provider - often storing data in Australian data centres for compliance.
Pro: Outsourced management (scheduling, encryption, verification). Suited for smaller IT teams needing professional oversight.
Con: Must ensure the provider meets local data residency rules, plus an exit strategy if switching vendors.
5. Disaster Recovery as a Service (DRaaS)
5.1 What Is DRaaS?
Definition: A specialised offering where a third-party provider hosts and orchestrates your failover environment, typically in the cloud.
Why: Minimises in-house hardware or data centre overhead, transferring technical complexity to the DRaaS provider.
5.2 How It Works
Replication: The DRaaS vendor continuously copies your VMs or data to their infrastructure.
Failover: If your primary site fails, you invoke a failover process - booting your workloads on the DRaaS platform.
Failback: Once the primary site is restored, data changes sync back, and you revert operations to normal premises or cloud.
5.3 Key Considerations
Local Data Residency: Ensure the DRaaS provider uses Australian-based data centres or meets local privacy obligations.
Testing: Regular failover drills to confirm RTO/RPO alignment.
Cost: Typically, subscription-based, reflecting storage, replication, and possible runtime charges during failover.
6. Selecting the Right DR Approach
6.1 Assess RTO and RPO
Why: High availability demands near-zero downtime (thus replication). Less critical operations can endure hours or days offline with simpler backups.
How: Conduct a business impact analysis (BIA) - which systems can you afford to have offline, and for how long?
6.2 Budget vs. Risk Tolerance
Why: Real-time replication or DRaaS is costlier but yields minimal data loss and downtime. Tapes or cloud backups are cheaper but slower.
How: Weigh potential downtime costs (lost revenue, brand damage) versus ongoing DR expenses.
6.3 Data Locations and Compliance
Why: If storing personal info, ensure alignment with Australian Privacy Principles (APPs). Consider local Australian data centres to avoid cross-border issues.
How: Confirm providers’ data residency disclaimers. Use encryption to protect data in transit and at rest.
6.4 Testing and Maintenance
Why: DR solutions fail if backups or replication drift out of sync, or if staff don’t practise.
How: Schedule at least annual full-scale tests or partial tests quarterly, verifying logs for anomalies.
7. Role of a Managed IT Services Provider
A Managed IT Services partner can:
Analyse Needs: Identifying RTOs/RPOs, listing critical apps, proposing solutions (onsite, cloud, DRaaS).
Design and Deploy: Setting up backup schedules, replication scripts, or DRaaS solutions that conform to Australian data laws.
Regular Testing: Conducting failover simulations, verifying data integrity, fine-tuning runbooks.
Monitoring: Watching backup health or replication status 24/7, alerting if issues threaten your recovery posture.
Incident Response Integration: Linking DR with incident response plans for coordinated action during major breaches or disasters.

Data Loss
Did any critical data points fall outside the intended RPO if a failover or restore was triggered?
Test Success Rate
Are all essential systems successfully recovered during drills, or do repeated issues crop up?
Cost and Efficiency
Balancing monthly or annual DR spend with the avoided downtime cost if disaster strikes.
Staff Readiness
Are teams confident in performing failover steps? Are processes documented and updated?
