A successful backup job answers one important question: was a copy created? Disaster recovery answers a harder one: can the business resume an acceptable level of operation within the required time?
Begin with business services
Define the services the firm must restore, such as market access, order management, market data, portfolio and risk systems, communications, remote access, file services, and client operations. Then map the technology and vendors each service depends on.
Set RTO and RPO that the architecture can meet
Recovery time objective describes the tolerated restoration time. Recovery point objective describes the tolerated data loss. Both require agreement between business and technology leaders, then validation against the actual design.
Account for identity and network dependencies
A recovered application may still be unusable without DNS, directory services, MFA, certificates, firewall policy, routing, market connectivity, or user endpoints. These dependencies belong in the recovery sequence and the test.
Write the decision path
Identify who declares an incident, who can authorize failover, who coordinates vendors, who communicates with leadership and users, and what conditions trigger a return to the primary environment. Include deputies and out-of-band contacts.
Test scenarios, not only restores
A file restore is valuable, but it does not test a site outage, identity compromise, ransomware event, carrier failure, cloud-region issue, or unavailable key person. Use bounded scenarios with success criteria and record the gaps.
Every material application, network, identity, vendor, or staffing change can invalidate an assumption. Tie recovery documentation to change management.
Preserve a usable evidence trail
Keep backup reports, restore validation, test plans, timestamps, decisions, issues, remediation owners, and retest results. The record supports improvement, leadership oversight, client diligence, and post-incident review.
