Google archive storage is $1.20/TB/mo. I just had a customer recommend it to me (I'm the author of HashBackup). He said he's been using it for over a year and pays around $3/mo for 2.5TB. One gotcha: the minimum storage duration is 365 days, so if you upload a 1TB then immediately delete it, you're going to still pay $14 over the next year. I really dislike "delete penalty" fees, but they're common.
