儲存用量到底量哪一層？

訂判斷及所需輸入

一個假設物件原內容八十單位，壓縮後實存三十，有兩份儲存副本。三種已訂計法是八十、三十及六十，只寫「儲存」未選定量哪層。

程序只用題內已量數值，不估真實壓縮比例或供應商帳單。這裏副本數按報價量儲存內容，未代表獨立復原環境。

按邊界依據作判斷

單份模式仍三十，即使有兩副本也一樣。量法缺漏，就先停下比較。

訂明量哪一層
取該層實量
再套副本計法

量法未知便保留未明，不自估壓縮大小。

可編輯邊界輸入及結果
條件	輸入 JSON	預期輸出 JSON
只量單份儲存	{"basis":"one-stored-copy","logical":80,"stored":30,"copies":2}	{"basis":"one-stored-copy","measuredUnits":30}
量法定義欠缺	{"basis":null,"logical":80,"stored":30,"copies":2}	{"held":true}

原例全部副本計，應是多少？

查看參考答案

六十，兩份各三十。八十是原內容大小，不能代替此報價基準。
