I use duplicity to backup my VPS to S3, and Fast Glacier to archive stuff to Glacier from my Windows machine (things like photographs, important documents etc.) Note: Glacier is not a backup service, it's an archive service. It's for long term backups, vs the relatively short term of standard backups (Full, delta, delta.. cycles). With Glacier if you delete an archive before 90 days, you'll still be charged for the full 90 days of storage.
