How to answer a disaster recovery question in an RFP

Scope

Define what returns to service before stating how fast

Start with the buyer-facing service and the minimum usable state after recovery. Name product edition, production environments, regions, data categories, interfaces and relevant optional modules. Then list the technology needed to restore that state: identity and privileged access, network and DNS, cloud control plane, encryption keys and secrets, compute, databases, object stores, queues, code and configuration, monitoring, integrations and notification channels. A platform is not recovered merely because the primary database is online.

Define the disruption scenarios covered by the design and those that need another process. Hardware failure, availability-zone loss, regional outage, data corruption, destructive cyber incident and loss of a critical supplier can require different recovery paths. Replication may support infrastructure failure but be unsuitable as the sole answer to corruption. A clean cyber recovery may require investigation, credential rotation, integrity validation and a known recovery point before service restoration.

Place disaster recovery beside, not inside, business continuity. Disaster recovery concentrates on restoring information systems, operations and data. Business continuity addresses how priority activities continue through disruption, including people, workplaces, communications, manual workarounds and supplier arrangements. Show the handoff: a manual workaround may bridge the time before system recovery, and business owners may set the priority, but neither replaces tested technical restoration.

Targets

Give RTO and RPO a clock, boundary and service level

NIST defines recovery time objective in relation to the period a system can remain in recovery before mission or business impact becomes unacceptable. In the answer, define the operational clock. State the triggering declaration or detection event, the service state required to stop the clock and whether validation, data reconciliation, customer connection and backlog recovery are included. Distinguish the target from maximum tolerable downtime and from any contractual availability or restoration service level.

Define RPO as the point in time to which data can be recovered and apply it to each material data class. A database transaction log, document store, configuration repository and external integration may have different protection. State time basis, backup or replication method, protection against alteration, retention, encryption, geographic placement and validation. “No data loss” needs an architecture and scope that actually support it; it is not a synonym for frequent replication.

Present four states separately: business requirement, approved design target, tested achievement and proposed buyer commitment. A test that restored service in two hours does not automatically create a two-hour guarantee. Conversely, a four-hour target with a six-hour test result needs an exception and corrective action. Where the buyer asks for a stronger target, identify the architecture, operational coverage, test regime, price and authority needed before offering it.

• Define trigger, clock start, stop condition and required service state.
• Apply RPO to every material data store and transaction path.
• Separate target, designed capability, achieved result and contract promise.
• Name assumptions and customer prerequisites.
• Escalate any gap instead of silently changing the target.

Method

Explain the dependency chain from declaration to reconstitution

Describe roles and sequence rather than attaching a policy title. Cover incident assessment, authority to declare disaster, recovery-team activation, communication, access to recovery resources, selection of the recovery point, infrastructure restoration, configuration and secret recovery, application start, data integrity checks, interface reconnection, service acceptance, backlog handling and return to normal operation. Show which steps are automated and which require human decision.

Map external responsibility. A cloud provider supplies defined infrastructure capabilities, but the SaaS provider remains responsible for configuring, testing and operating its recovery design. Subprocessors may have their own targets that constrain the service. Customer actions may include maintaining contacts, enabling alternate endpoints, providing encryption material, validating restored data or reconnecting an interface. Put each dependency beside an owner, precondition, communication route and expected time.

Explain control after restoration. NIST SP 800-53 distinguishes recovery from reconstitution to a known state and includes validation needed to return systems fully to operation. State how the team confirms integrity, security controls, monitoring, data completeness and customer function before declaring recovery complete. Include how temporary recovery capabilities are retired, evidence is retained and lessons or plan updates are approved.

Evidence

Describe what the recovery test actually exercised

Classify the exercise: document review, tabletop, backup restore, component test, technical failover, full recovery and reconstitution, or an actual event. Give date, covered service, environment, scenario, starting state, participants, customer involvement and exclusions. State the measured recovery point and elapsed stages using the approved definition. Do not call a discussion an executed failover or a database restore an end-to-end service recovery.

Report result and limitation together. Identify whether target was met, which systems or interfaces were excluded, what manual intervention occurred, whether production-scale data was represented and what evidence was captured. Summarize material findings and corrective actions without exposing sensitive procedures. Give owner, due date and closure evidence for an open issue. A clean marketing sentence that removes the exception makes the test less useful to the evaluator.

Finish by reconciling every surface. The disaster-recovery answer, business continuity section, architecture diagram, security questionnaire, service levels, data schedule, contract exceptions, implementation plan and price must use the same scope and targets. Confirm that cited reports can be shared through the proposed confidentiality route. Route any stronger wording to infrastructure, security, service, legal and commercial approval before release.

• Name exercise type and exact recovery path.
• State environment, scale, scenario and exclusions.
• Report measured results with the clock definition.
• Disclose material gaps and corrective-action status.
• Reconcile the approved claim across proposal and contract.
