I would not do this with backups for all the reasons @girish has mentioned (ie you'd have to restore the objects to standard before you'd be able to use them and this could take a while, not what you want when you need to quickly restore a backup), but what you could do if you really wanted to is to move older backups to Glacier automatically after a certain amount of time using automated lifecycle rules
