A disaster recovery plan can look complete on paper and still fail when an organization actually needs it.
Recovery procedures may be outdated. Critical dependencies may have been overlooked. Backups may not be usable. Recovery times may be longer than expected. Or infrastructure at the recovery site may not be compatible with the workloads that need to run there.
For organizations relying on IBM Power and other mission-critical infrastructure, a modern IBM disaster recovery plan needs to address more than backup.
It needs to define recovery objectives, protect critical data, establish resilient infrastructure, document recovery procedures, and regularly test whether the organization can actually recover.
The good news is that disaster recovery planning doesn't have to be a once-a-year exercise. It can become an ongoing process for improving data resilience and business continuity.
Before evaluating technology, determine what the business actually expects from disaster recovery.
Two measurements are particularly important:
RTO defines how quickly a system or application needs to be restored after an outage.
For example, a business-critical application may need to be operational within one hour, while a less critical system may be able to remain offline for a day.
RPO defines how much data loss the organization can tolerate, measured in time.
If an application has an RPO of 15 minutes, the recovery strategy needs to support a recovery point that limits potential data loss to approximately that timeframe.
RTO and RPO should not be arbitrary numbers. They should reflect the business impact of downtime and data loss.
A disaster recovery plan should begin with an accurate inventory.
Organizations should identify:
Then classify those resources according to business criticality.
Not every workload requires the same recovery strategy.
A tiered approach allows organizations to prioritize resources and allocate recovery investments where they matter most.
Storage is one of the most important components of an IBM disaster recovery plan.
A recovery strategy is only as strong as the data available when recovery begins.
Traditional backups remain an important component of data protection, but modern disaster recovery strategies also need to consider ransomware, corruption, accidental deletion, and compromised recovery points.
IBM FlashSystem provides capabilities designed to support resilient storage architectures, including immutable and isolated copies and replication options for disaster recovery.
Immutable copies can help protect recovery points from unauthorized modification or deletion, while replication can provide access to data at another location when production storage becomes unavailable.
The architecture should be designed around the organization's RTO and RPO requirements rather than simply selecting a backup technology and working backward.
One of the biggest mistakes organizations can make is assuming that a successful backup automatically means a successful recovery.
It doesn't.
A backup job can complete successfully while recovery still fails because:
That is why recovery testing is so important.
IBM's storage and resiliency technologies provide capabilities that can support recovery validation and protected recovery points. IBM Storage Defender, for example, provides visibility across protected environments and supports recovery testing capabilities.
Testing is where a disaster recovery plan moves from documentation to reality.
Organizations should conduct regular recovery exercises that simulate realistic scenarios.
Examples include:
Testing should measure more than whether data can be restored.
It should determine whether the entire recovery process works.
Can infrastructure be brought online?
Can applications connect to their databases?
Can users authenticate?
Can networking support the recovered environment?
Can the organization meet its RTO?
Is the recovered data within the required RPO?
Testing can expose gaps that are difficult to identify during a documentation review.
Even a technically sound recovery environment can fail if the people responsible for recovery don't know what to do.
Documentation should include:
Documentation should also identify who is responsible for each stage of recovery.
If recovery depends on one employee knowing a specific procedure, the organization has a resilience risk.
For organizations running IBM Power workloads, disaster recovery planning needs to account for the compute environment as well as storage.
IBM Power provides a highly reliable platform for mission-critical workloads across IBM i, AIX, and Linux environments.
IBM also offers technologies such as VM Recovery Manager for Power to support automated high availability and disaster recovery for AIX, IBM i, and Linux workloads. The solution can automate failover and support non-disruptive DR rehearsals.
The important consideration is how these capabilities fit into the organization's overall recovery architecture.
Storage, compute, networking, applications, and recovery procedures should be designed as a connected system rather than separate pieces.
A modern IBM disaster recovery plan should consider resilience at multiple levels.
At the storage layer, organizations can use technologies such as IBM FlashSystem to support protected recovery points, replication, and rapid restoration.
At the compute layer, IBM Power provides a resilient platform for critical workloads.
At the operational layer, documented and tested procedures help ensure the technology can actually be used when an incident occurs.
And at the business level, RTO and RPO requirements provide a framework for determining whether the overall strategy is sufficient.
This layered approach helps move disaster recovery from a collection of backups to a comprehensive data resilience strategy.
Your infrastructure changes constantly.
New applications are deployed. Systems are retired. Data volumes increase. Cloud services are added. Network architecture changes. Employees and responsibilities change.
Your disaster recovery plan needs to change with them.
At minimum, organizations should review their plans whenever there is a significant infrastructure or application change and conduct periodic recovery testing to validate assumptions.
Testing should produce actionable findings.
If recovery takes four hours and the RTO is two hours, the solution isn't to change the RTO on paper. The organization needs to determine what infrastructure, process, or technology changes are required to close the gap.
A successful disaster recovery strategy requires more than selecting backup software or purchasing additional storage.
It requires an understanding of the organization's applications, infrastructure, data, dependencies, recovery requirements, and business priorities.
ProActive Solutions brings experience across data center transformation, backup and recovery, storage, cybersecurity, and IBM Power infrastructure. Our engineers have senior-level expertise in IBM Power, AIX, and System i, allowing us to evaluate recovery requirements across the infrastructure rather than looking at storage or compute in isolation.
ProActive can help organizations:
The best disaster recovery plan isn't the one with the most pages.
It's the one your organization knows will work.
That confidence comes from clearly defined recovery objectives, resilient storage, compatible infrastructure, current documentation, and regular testing.
IBM Power and IBM FlashSystem provide technologies that can support this approach, but the right architecture depends on your workloads, business requirements, and existing environment.
Is your IBM disaster recovery plan ready for a real-world recovery scenario?
ProActive Solutions can help assess your current strategy and identify opportunities to improve resilience, recovery, and business continuity.
