How Long Storage Fit Retain Data

Compare usable storage with new data for each day and number of stored copies.

Your numbers

Retention time wey model estimate

—

Planning estimate with the parameters wey you enter. E no contact external service, device, live tariff or network.

Formula

Use D = 1000T(1−r)/(gc). T na capacity for decimal TB, r na reserve fraction, g na new GB per day, c na copy count, and D na retention days.

Compare usable storage with new data for each day and number of stored copies.

Example wey show the calculation

Capacity wey you fit use (TB, decimal): 10
New data wey enter every day (GB): 100
Number of stored copies: 2
Share of capacity wey you reserve (%): 20

Retention time wey model estimate: 40 days
