I meant more monetary cost. Nominally cloud storage for one unit of storage and one unit of time is perfectly "fine". Except that it adds up. More storage, indefinitely held, multiple hosts. Data which needs to be copied from one to the other which incurs costs from both. Add to this routine retrieval costs - if you "live this way". And routine test retrieval costs if you know what's good for you.

So last time I looked, unit costs were low - sure. But all-included costs were high.
