How a Disaster Recovery Review Works
A Disaster Recovery Review typically begins by identifying critical business services and the technology components supporting them. Reviewers then compare required recovery outcomes with documented procedures, available backups, infrastructure arrangements, and assigned responsibilities.
The assessment should distinguish between systems that are essential for immediate operations and those that can be restored later. Financial applications often receive priority because prolonged disruption can affect invoicing, payments, collections, payroll, treasury, and financial close activities.
- Business priorities: Identify critical finance and operational processes and establish recovery priorities.
- Technology dependencies: Map applications, databases, integrations, infrastructure, and third-party services.
- Recovery controls: Evaluate backup schedules, restoration procedures, access rights, and recovery environments.
- Testing evidence: Review recovery exercises and documented results against recovery objectives.
Key Recovery Objectives and Metrics
Two important measures are the Recovery Time Objective (RTO) and Recovery Point Objective (RPO). RTO represents the targeted maximum time required to restore a service, while RPO represents the acceptable amount of data loss measured in time.
For example, if an accounts receivable system has an RTO of 4 hours and an RPO of 30 minutes, the recovery design should aim to restore the service within 4 hours while limiting potential data loss to approximately 30 minutes of transactions.
Other useful review measures include backup success rates, recovery-test completion rates, restoration duration, unresolved recovery actions, system dependency coverage, and the percentage of critical applications with documented recovery procedures.
ERP and Finance System Recovery
Finance systems often depend on interconnected ERP modules, databases, payment platforms, banking interfaces, reporting tools, and external services. ERP Disaster Recovery addresses the recovery of ERP environments and their integrations so that critical financial workflows can resume in a controlled sequence.
A Disaster Recovery Review should therefore trace dependencies rather than examining individual applications separately. For example, restoring an ERP database may not fully restore procure-to-pay operations if supplier records, approval services, authentication systems, or banking interfaces remain unavailable.
Procurement continuity should also be considered. A recovery exercise can verify whether a purchase order can be retrieved, approved, matched, and posted after restoration, including the supporting vendor and accounting data required for the transaction.
Financial Data, Reporting, and Controls
Recovery arrangements must preserve the integrity and availability of financial information. Reviewers should examine whether restored accounting data maintains transaction history, audit evidence, account mappings, and reporting structures.
The chart of accounts is particularly important because reporting depends on consistent account structures and mappings. Recovery procedures should verify that restored financial data can support the general ledger, financial statements, management reporting, and required reconciliations.
Tax processes also require continuity planning. A restored finance environment should preserve relevant sales tax configurations, jurisdiction rules, exemption information, and transaction records so that tax reporting and validation remain aligned after recovery.
Recovery Testing and Operational Evidence
Disaster Recovery Planning establishes the documented strategy, responsibilities, procedures, priorities, and resources required to recover business services. A Disaster Recovery Review assesses whether that planning reflects the organization's current technology and finance environment.
Disaster Recovery Testing provides evidence that documented recovery procedures can be executed and that expected recovery objectives are achievable. Testing can include application restoration, database recovery, infrastructure failover, data validation, user access verification, and end-to-end finance transaction checks.
Vendor and third-party dependencies should also be incorporated into recovery evidence. Audit Trails can preserve records of vendor-management actions performed by humans or AI, supporting transparency and review when organizations validate activity following a disruption.
Best Practices for Disaster Recovery Reviews
An effective review should be evidence-driven and updated whenever major systems, integrations, vendors, infrastructure, or financial processes change. Recovery documentation should identify owners and escalation paths rather than relying solely on technical instructions.
- Prioritize systems according to financial and operational impact.
- Maintain current application and integration dependency maps.
- Verify backup integrity and restoration procedures regularly.
- Test both technical recovery and end-to-end finance workflows.
- Document recovery results, exceptions, corrective actions, and responsible owners.
- Reassess recovery objectives after major technology or business changes.
Summary
Disaster Recovery Review evaluates whether an organization can restore critical systems, data, and financial processes within defined recovery objectives. It combines business priorities with technical evidence covering backups, restoration, dependencies, controls, testing, and operational responsibilities.
For finance organizations, the review should extend beyond infrastructure recovery to confirm that ERP processing, accounting records, procurement, tax validation, reporting, and audit evidence remain usable after restoration. Regular assessment and testing help strengthen business continuity, financial reporting reliability, and operational resilience.
