A more realistic view
A backup strategy is not only about today's space: it also grows, multiplies and needs margin.

Clear guides and calculators for digital storage.
Storage
Estimate how much space your backup strategy may require over the next 12 months based on current size, monthly growth, number of copies and a safety margin.
Approximate annual scenario for a current 500 GB library with growth and two copies.
Suggested capacity so the strategy does not run short at that pace.
Inputs
Estimated result
With these values, your backup strategy could require around 2.10 TB in 12 months.
A backup strategy is not only about today's space: it also grows, multiplies and needs margin.
Useful to avoid running short when choosing external drives, SSDs or network storage.
If you keep more than one copy, real storage demand can grow much faster than expected.
Use it as a planning reference, not as a replacement for measuring your actual library.
