Check Photo Archive Size Before the Drive Fills
Two copies of a shoot double the space you need, and the drive you bought last year is already partly full. Add the written volume in order and see where a rotation is due.
1 · shoot | shoot size gigabytes | copies required
FIRST-LOAD
Research prototype — checkout unavailable. Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the backup rotation strip: your shoot | shoot size gigabytes | copies required stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Storage needs double when the rule is two copies. After: the backup rotation strip shows the working beside each named row so the reader can change the assumption and inspect the consequence.
2 · Read the backup rotation strip
This is storage arithmetic from sizes you supply and is not a backup guarantee. Verify every copy by opening files from it, keep at least one copy off-site, and replace drives according to the manufacturer’s guidance.
Paid layer: backup rotation strip print and history
one-time step · the free reading above stays complete
Free tier

What $4 one-time adds
- print the backup rotation strip with its row workings
- CSV of gigabytes written and row explanations
- last five reading summaries saved in this browser profile
$4 once for repeated filing of the backup rotation strip, not for a better answer. Illustrative time basis: avoiding one five-minute manual reformat per saved reading; no market-price or guaranteed-savings claim.

Checkout is unavailable until a payment link is configured. The optional unlock is browser-local, profile-scoped and best-effort, not server-verified access. Clearing browser data can remove it; there is no account or cross-device recovery.
Boundary and sources

- Method: The running total passing the drive capacity is flagged, because that is the point where the next shoot needs a second drive or a bigger rotation. The sample writes 680 gigabytes in total against a 500-gigabyte drive.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.
Mechanism: competence-autonomy-loop
Optional AI formatting, not calculation
For this backup rotation strip, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a backup rotation strip. Return plain rows only: shoot | shoot size gigabytes | copies required. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: shoot | shoot size gigabytes | copies required. No AI response is executed as code.
