WIth Amazon Glacier costs are in the magnitude of $0.01 per gigabyte per month. You don't have a real-time access to data and thus the backup process must be managed with some more care, but being a long-term backup this is hardly a problem.

To me that's not cost effective and needs to go down another order of magnitude to be interesting for me. Let's say my total data set is 3TB. That'll be $30/month or $360 a year. I can easily buy 3 consumer grade 3TB hard disks for that much with change left over (keeping two local at all times, cycling the 3rd one offsite), and that will last multiple years. Personally I don't use 3 copies, only two, so the cost is even lower.
