Ideal storage for redundant backups

I'd like to use Glacier for weekly redundant backups which will roll over only at the minimum mark (90 or 180 days, whichever), it'd only be accessed in the event of catastrophic failure of our other backup systems. Ideally the storage method would be the least expensive for saving data, but available to download, or retrieve in any other method, as quickly as possible even if at a very high cost. Some time ago I read that certain services would courrier you a storage device with all of the necessary information within hours of your request, is such a thing possible with Glacier? I'd probably select the Canada-central region, as we're in the Montreal area, if that matters. Thanks!
