A family member has uploaded a backup of all of the family photos to Amazon Glacial Storage, on the order of a few hundred GB, and gleefully sends me screenshots of the <$1/mo charges.
AWS Glacier is cold storage, for things like legally mandated retention that you never need to access, or for humans, say digitizing your grandma's 35mm slides. It's not the same use-case as typical file backup, with performance that's probably not acceptable if you want a file (or even a listing) <now>. Good rule of thumb: Glacier is for things that you might need but ideally will never access again.
