The Missing Amazon Glacier Cost-Estimator

As reported here, storage pundits have been dubious as to claims by Amazon that their new AWS Glacier cloud archiving service is a tape killer. At a penny per gigabyte per month, the press release had some journalists eating the dog food with speculations that Glacier could make tape silos obsolete.

But wait. Was Amazon leaving out crucial pieces of the comparison puzzle? Now J. Brandt Buckley has posted a Amazon Glacier Cost-Estimator Calculator to help elucidate the relationship between cost, data retention periods, and recovery scenarios.

    The buckley calculatior is wrong. It does not include the significant cost of “requests” associated with UPLOADING data to Amazon Glacier. Upload some data, wait a month for you bill, and you will see.
