I've recently been looking at it too, and trying to find clarification of the retrieval fee. It seems there's a lot of (potential) misinformation, though I'm still trying to verify that. My guess is the best idea is to upload to S3, using whatever tools you can for that, and then archive from S3 to Glacier using the AWS lifecycle rules. See previous discussion at http://news.ycombinator.com/item?id=4411536 http://news.ycombinator.com/item?id=4411536 and http://liangzan.net/aws-glacier-calculator/ http://liangzan.net/aws-glacier-calculator/ - my concern is that they don't seem to match Amazon's Glacier calculator at http://calculator.s3.amazonaws.com/calc5.html http://calculator.s3.amazonaws.com/calc5.html http://alestic.com/2012/12/s3-glacier-costs http://alestic.com/2012/12/s3-glacier-costs also seems relevant. So be sure you know what you're getting yourself into, otherwise you could end up with thousands of USD in billing. If you get clarity on the retrieval fee, please let me/us know.
