Have to be careful with Glacier: the retrieval costs can be very high and are extremely hard to calculate. Amazon S3 Infrequent Access has higher retrieval costs, though not as crazy as Glacier, and a delete penalty. Deleting a file after 1 day will cost 30x normal S3 storage fees. Likewise, Coldline sounds great, but they have higher retrieval fees (not so bad) and a delete penalty. The Coldline delete penalty will cost 90x the regular storage cost if a file is deleted the next day. I don't recommend Coldline unless you know you won't be deleting files before 90 days.
