Estimate retained-copy storage without hiding assumptions

Last materially reviewed 2026-10-01

Quick answerA full-copy estimate is useful only when its assumptions remain visible.
Likely to work well when

✓ Small-team database recovery planning

✓ Native versus managed backup decisions

✓ Isolated rehearsal and operating-cost records

Important limitations

— Live incident command execution

— Guaranteed failover or recovery

— Security or compliance certification

— Laptop-only backup shopping

What to know

A deliberately simple model

Multiply estimated stored size per copy by the number of retained copies and destinations. This is a planning model for full copies. It does not model deduplication, incremental chains, compression ratios, versioning, minimum storage duration or provider request charges. Use observed artifact sizes rather than raw database size when available.

What to know

Separate schedules

Daily and monthly copies can have different retention rules and may overlap. Account for the actual behavior of your tool rather than assuming duplicates disappear. If you disable rotation, a fixed copy-count estimate no longer describes ongoing growth. Revisit the model when schedules or artifact size change.

What to know

Compare the complete bill

Enter your own current storage unit price and add retrieval or operational costs separately. The worksheet is not a merchant quote. A small monthly storage saving may be irrelevant if the chosen tier delays recovery or makes the procedure harder to operate.

What to know

Use the result as a question

If the estimated footprint is surprisingly large, inspect the retention objective before shortening it. The right response may be a layered schedule, a different storage class or an explicit policy decision. Never delete recovery history only to match a calculator result.

What to know

Reproduce the fictional full-copy example

A stored artifact of 5 decimal GB, retained fourteen times across two destinations, produces a modeled footprint of 140 GB. At a fictional price of 0.02 currency units per GB per month, storage alone is 2.80 per month. This is not a SimpleBackups or storage-provider quote. It assumes every retained copy is full-sized and priced alike. If one destination uses a different rate, calculate it separately and add the results; do not average rates without weighting the actual retained footprint.

The evidence behind this buying guidance

This guide draws on SimpleBackups retention behavior, SimpleBackups backup storage. Merchant-controlled records describe the provider’s own capabilities, terms or standards; they do not independently validate those claims. These records do not establish independent confirmation of the product claims.

Verify any current price, plan limit, label direction, compatibility rule, or commercial term that would materially change the decision. The dated source ledger shows the underlying records so this conclusion can be checked and updated.

What footprint are you retaining?

Full-copy model: stored GB per copy × retained copies × destinations. Monthly storage only; excludes requests, retrieval, compression and incremental behavior. One currency throughout.

All fields required. Use zero only when it is known—not as a substitute for an unmeasured stage.
