There are three ways to retrieve data from Glacier and each has a different per-GB retrieval fee and per-archive request fee (i.e. requesting one archive counts as one request). Expedited retrievals costs start at $0.03 per GB and $0.01 per request. Standard retrievals costs start at $0.01 per GB and $0.05 per 1,000 requests. Bulk retrievals costs start at $0.0025 per GB and $0.025 per 1,000 requests.
For example, using Expedited retrievals in the US East (Northern Virginia) region, if you requested 10 archives with a size of 1 GB each, the cost would be 10 x $0.03 +10 x $0.01 = $0.40.
If you were using Standard retrievals in the US East (Northern Virginia) region to retrieve 500 archives that were 1 GB each, the cost would be 500GB x $0.01 + 500 x $0.05/1,000 = $5.25
Lastly, using Bulk retrievals in the US East (Northern Virginia) region, if you were to retrieve 500 archives that are 1 GB each, the cost would be 500GB x $0.0025 + 500 x $0.025/1,000 = $1.2625.
When an archived object is retrieved, it resides in both RRS and Glacier.
