Why This Tool Matters
Backup and DR design is often overestimated, underestimated, or based on incomplete data assumptions. This tool helps identify realistic protection scope, likely backup footprint, dark data impact, and the DR pattern that best aligns with recovery expectations.
Reduce Recovery Risk
Identify whether current recovery assumptions are too weak for business-critical workloads and whether the expected DR outcome is realistic.
Avoid Over-Sizing
Estimate backup storage more realistically instead of protecting all stored data blindly without considering retention, growth, or redundancy.
Expose Dark Data
Highlight redundant, obsolete, duplicated, or unclassified data that may be increasing storage and backup cost unnecessarily.
Guide DR Direction
Recommend whether backup-only, pilot light, warm standby, or a more resilient DR model is more appropriate for your environment.
Sizing Methodology
This sizing model estimates your protection-worthy data baseline after adjusting for dark data, then applies retention, daily change rate, growth assumptions, and archive uplift to produce an advisory backup storage estimate. Recovery objectives and workload criticality are then used to recommend the most suitable DR pattern.
Protected Data Baseline
Total primary data is adjusted using dark data indicators to estimate the amount of data that genuinely requires protection.
Footprint Estimation
Retention, daily change rate, growth assumptions, and archive needs are applied to estimate likely backup storage requirements.
Recovery Interpretation
RTO, RPO, and critical workload ratios are interpreted to determine whether backup-only protection is sufficient or whether a stronger DR pattern is needed.
Risk Signalling
Dark data, missing ownership, and obsolete retained copies are treated as advisory warning signals that may increase cost and reduce recovery efficiency.
This tool provides an advisory estimate for early planning and discussion. Final architecture, storage sizing, and DR design should be validated against workload-specific technical and business requirements.
