Amazon Cloud Drive Backend for Duplicity
To follow up on my previous post, I wrote acdbackend, to add Amazon Cloud Drive support to duplicity, by wrapping around the acd_cli tool.
Actually, adding online storage services to duplicity is pleasantly easy to implement. If you have some command-line tool for your service that supports download and upload using stdin/stdout, file listing, and deleting files, then in an hour you can have it working in duplicity.
