What is Disaster Recovery?
Disaster recovery is the set of procedures and systems that let an organisation restore critical applications and data after a major disruption such as an outage, data loss or cyber attack. It defines how quickly services are restored and how much data, if any, can be lost.
How does disaster recovery work?
Disaster recovery is the planned response to events that take systems offline - hardware failure, data corruption, a cloud region outage, a ransomware attack or a natural disaster. A disaster recovery plan documents exactly how critical applications and data will be restored, who is responsible for each step, and in what order services come back. It depends on having reliable backups, replicated systems or standby infrastructure ready to take over, so recovery is a rehearsed procedure rather than an improvisation under pressure.
Two metrics define the goals. The recovery time objective (RTO) sets how quickly a service must be restored, and the recovery point objective (RPO) sets how much data the business can afford to lose, measured as the time between the last usable backup and the failure. These targets shape the design and cost of the whole approach.
Why disaster recovery matters
Downtime and data loss are expensive in revenue, reputation and trust, and they rarely happen at a convenient time. Without a tested recovery plan, an organisation discovers the gaps in its backups during the worst possible moment - the incident itself. Disaster recovery turns a potential catastrophe into a managed event with a known response, protecting business continuity and giving customers and regulators confidence that critical services can withstand a serious failure.
What does a disaster recovery plan include?
A practical disaster recovery plan typically defines:
- Recovery objectives - the RTO and RPO for each critical system.
- Backups and replication - what is copied, how often and where.
- Failover procedures - how systems switch to standby infrastructure.
- Roles and responsibilities - who does what during an incident.
- Testing schedule - regular rehearsals that prove the plan works.
Disaster recovery best practices
Set recovery objectives based on business impact, so the most critical systems get the strongest protection and you do not overspend on the trivial. Store backups in a separate location or region from the live systems, because a backup that fails alongside the primary is no backup at all. Most importantly, test the plan regularly - an untested recovery plan is an assumption, not a capability, and the time to discover a flawed backup is during a drill, not a real outage.
How PixelForce approaches disaster recovery
At PixelForce, disaster recovery is planned during Phase 2 - Development and maintained through Phase 3 - Post Launch Support, where our in-house Adelaide team keeps live products resilient. We design backup and failover around each product's real recovery objectives rather than a one-size-fits-all template, which is part of how we sustain 99.99% crash-free reliability across the products we run. For products built on AWS, this work runs through our AWS app migration services, and the automation that keeps recovery fast and repeatable connects to our AWS DevOps consulting.

Frequently asked questions
A backup is a copy of data that can be restored later. Disaster recovery is the broader plan and capability for getting whole systems and services running again after a major disruption, of which backups are one component. You can have backups without a disaster recovery plan, but you cannot have effective disaster recovery without reliable backups. Recovery also covers infrastructure, failover, roles and the tested procedures for restoring service quickly.
RTO, the recovery time objective, is the maximum acceptable time to restore a service after a failure. RPO, the recovery point objective, is the maximum acceptable amount of data loss, expressed as the time between the last usable backup and the incident. A low RTO means you must recover quickly; a low RPO means you can afford to lose very little data. Both targets drive the design and cost of a recovery solution.
A disaster recovery plan should be tested regularly - many organisations rehearse at least once or twice a year, and more often for highly critical systems. Testing is essential because plans drift out of date as systems change, and an untested plan often hides broken backups or out-of-date procedures. The point of a drill is to find those gaps in a controlled setting rather than during a real incident when the cost of failure is highest.
No. Cloud platforms provide strong building blocks - replication, multiple regions and managed backups - but they do not automatically protect against every failure, including accidental deletion, data corruption or misconfiguration. You still need a plan that defines recovery objectives, configures the right protections and is tested. The cloud makes good disaster recovery easier and more affordable to achieve, but it does not deliver it without deliberate design.
