Molly Rector from Spectra Logic writes that Amazon’s AWS Glacier cloud archival service is no “Tape Killer.”
Amazon Glacier is not practical for active archive markets with up to exabytes of data. Tape is. Bandwidth costs are too high, retrieval time is too slow and the Glacier model doesn’t meet the frequency of data access requirements. Just think about retrieval times: it would take about 40 days to move one (1) petabyte across an OC48 and 10 days to move it across 10 Gb/E. When talking about large data archive, local storage is a must.
