This is why I love GCP Cloud Storage. The "colder" tiers are cheaper, and reads simply cost a lot more from there, but they don't slow them down and take days to restore. You pay with dollars, not time for restoring those GCS backups. e.g. Coldline [1] simply has reduced availability in exchange for being cheaper (99.9-99.95% availability, so 43min/mo, way less than "two days").
