This paper is designed to examine the true cost of storing data in the AWS Glacier Cloud versus in an Iron Mountain Storage Facility. To source data for this paper, we used Spectra Logic as a ?real-world? example (Spectra uses both Amazon and Iron Mountain), and obtained actual quotes from both vendors. To allow users to make calculations and decisions based on their own data sets, we start by looking at the cost of storing 6TB of data (a single LTO-7 tape) using Amazon Glacier versus Iron Mountain.
