Illustrative Solution Scenario: Designing Backup and Disaster Recovery for Business-Critical Workloads
Illustrative only—not a completed customer project. This scenario demonstrates how business-impact findings can shape backup, recovery architecture, runbooks and validation.
This is a planning example, not a completed customer project or outcome claim.
Business context
Why the requirement exists.
A mid-sized organisation depends on virtualised line-of-business applications, databases, shared files and several cloud services. Backup jobs run, but retention settings differ, restore evidence is limited and several copies remain inside the same administrative and infrastructure boundary as production.
Leadership wants a clearer answer to two questions: how much data could be lost after a disruption, and how long would priority services take to restore? The organisation also needs to distinguish day-to-day file recovery from site-level disaster recovery and from high availability within its primary environment.
This illustrative scenario proposes a design and validation process only. It does not represent an Atmic customer, a completed deployment, a promised recovery time or measured business outcome.
Requirements
What the design must account for.
Create a business-service catalogue with owners, critical periods, impact and manual workaround information.
Agree target recovery time objectives and recovery point objectives by service.
Map applications to databases, identity, DNS, network, certificates, keys, storage and external suppliers.
Define backup frequency, retention, encryption, off-site separation and immutable or offline copy requirements.
Choose recovery patterns proportionate to each service rather than one design for the whole estate.
Protect backup and recovery administration from compromise of production identities where feasible.
Create invocation, technical recovery, communication and return-to-normal runbooks.
Establish safe restore and disaster-recovery exercises with evidence and action tracking.
Proposed approach
How the work could be sequenced.
1
Business impact and service mapping
Facilitate workshops to identify service impact over time, acceptable data loss, critical periods, dependencies and decision owners. Translate approved business objectives into a sequenced technical recovery scope.
2
Current-state evidence review
Review backup policies, repositories, job history, restore tests, network paths, storage, replication, identity controls, retention and supplier arrangements. Record gaps without treating a successful job status as proof of recovery.
3
Protection and recovery design
Assign backup, high-availability and disaster-recovery controls to each service. Select copy separation, immutability, recovery location, minimum capacity, connectivity, security and orchestration appropriate to the agreed objectives.
4
Runbooks and operational readiness
Document alert handling, restore requests, disaster declaration, escalation, recovery sequence, credentials, supplier contact, validation and failback. Assign named roles and keep an accessible controlled copy outside the primary failure domain.
5
Progressive validation
Begin with component restores and tabletop exercises, then conduct isolated service recovery and a planned failover where safe. Capture duration, dependencies, deviations and corrective actions after every exercise.
Architecture considerations
Decisions that shape the design.
Policy tiers aligned to business-service RPO, RTO, retention and legal requirements.
Protected copies separated across appropriate storage, location and administrative failure domains.
Encryption in transit and at rest with documented key ownership and recovery access.
Immutable or offline protection for selected data, with deletion authority restricted and monitored.
A recovery environment sized for the minimum approved service level, not assumed to mirror every production component.
Dependency-aware recovery order covering identity, DNS, network, databases, applications and user access.
Monitoring for job failure, stale protection, repository capacity, policy drift and recovery-platform health.
Secure runbook access, emergency credentials and communication channels available when primary systems are unavailable.
Expected benefits
Potential value—not guaranteed outcomes.
Recovery priorities tied to business impact rather than infrastructure labels alone.
A clear distinction between backup, local availability and disaster recovery investments.
Reduced reliance on copies that share production's primary failure or identity boundary.
Documented recovery ownership, authority, communication and supplier dependencies.
Evidence from restores and exercises that can guide further improvement and investment.
A staged roadmap that balances critical service needs with operational capacity and budget.
Validation plan
Evidence before acceptance.
Restore representative files, databases, virtual machines and application configurations into an isolated location.
Verify recovered data consistency and application function with the relevant service owner.
Measure actual recovery-point age and elapsed recovery steps against the approved test objective.
Test emergency access, key availability, DNS, network routing, certificates and external integrations.
Run a tabletop exercise covering declaration, leadership communication, technical coordination and supplier escalation.
Conduct a controlled service-recovery exercise with explicit safety, rollback and production-isolation controls.
Track findings to owners and retest material corrections before reporting the capability as ready.
