Can someone using S3 Glacier as a backup destination please provide some concrete costs? Even if no retrieval is involved, I'd just love to see: "I pay $XYZ and am backing up ###GB worth of data."

I see the calculator floating around in the comments, but it's not formatted in a backup-friendly fashion / use case (ie. set storage size with XYZ% churn for changed files, or continuously expanding snapshots with aged snapshot deletion).

I've always been curious for usage for backup storage. The costs for retrieval are expensive enough (in the time frames I'd care to see for a personal computer) that I think I'll still avoid that aspect for the time being.

Just got the AWS bill. I accidentally started backupping my entire MacBookPro (200 something Gig) and only found out about half way through. Began a new session for the 'Documents' folder only (about 20 gig). The bill was $ 2.03 But Amazon will charge me about $ 0.10 for every Gig I want to retrieve (Glacier). ARC support was quick and good by the way.
It's cheap until you have to grab a bunch of stuff back all at once. Then they have you by the short hairs.
I think if your house/company burned down and you loose yor main PC and the external backup, you'd be glad to pay 0.10 cents for every Gigabyte you can retrieve.
Or potentially higher than 20x that much, if you are downloading it quickly (are you actually aware of the Glacier pricing model? where did you obtain $.10/GB?).

But it's not like S3 and no backup at all are the only two options. There's loads of backup providers (Carbonite, Mozy, Backblaze etc) out there. The comparison needs to be against those.
When you add a folder to Arq (and you're using AWS for a target) it asks whether you want S3 or Glacier and gives a chart of costs: http://www.haystacksoftware.com/storage_type_selection.png
I just got my bill for Feb. I am currently storing 15gb, and it cost me $0.21.
