Storage Retention Time
Compare usable storage with daily generated data and replicas.
Your numbers
Estimated retention
Planning estimate using your entered parameters. No external service, device, live tariff or network is contacted.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use D = 1000T(1−r)/(gc). T is capacity in decimal TB, r is the reserve fraction, g is new GB per day, c is the copy count, and D is retention days.
Compare usable storage with daily generated data and replicas.
Worked example
- Usable capacity (TB, decimal)
- 10
- New data per day (GB)
- 100
- Stored copies
- 2
- Reserved capacity (%)
- 20
- Estimated retention
- 40 days
Scope and limitations
Planning estimate using your entered parameters. No external service, device, live tariff or network is contacted.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
