Every calculation, explained.
Future logical data = current TB × (1 + annual growth / 100)years.
Primary usable target = future logical TB ÷ reduction factor ÷ (1 − reserve / 100).
Combined usable target = primary usable target × (1 + additional full-copy equivalents).
Network-only transfer hours = future logical TB × 8 × 10¹² ÷ (Gbps × 10⁹ × efficiency / 100) ÷ 3,600.
The same reduction and reserve assumptions are applied to every modeled copy. This is a usable-capacity model; RAID, erasure coding, metadata, spare drives and other raw-capacity overhead are excluded. Transfer time assumes uncompressed logical data and a sustained link. Storage throughput, file counts, verification, application restart and contention can extend recovery. Do not treat this as an RTO commitment. Validate reduction using your actual data.
