Using Duplicity to back up to Linode Object Storage

This is more of a how-to than a question, since I didn't see it asked or answered previously when I first looked into it. I had previously used Duplicity to back up documents on a home server to the free space on a Linode VPS, but I was starting to bump into capacity restraints. Linode Object Storage is advertised as S3-compatible, and Duplicity is supposed to be able to use any S3-compatible storage, so why not move the backup to Object Storage? This blog post describes how I did it:
