Duplicati is a rewrite of duplicity/ftplicity, written for Windows (in managed C# .NET). It also runs on Linux using the Mono framework.
The lastest portable version in all 5 languages you can download from http://code.google.com/p/duplicati/downloads/list (last zip-file)
The initial backup is sent in encrypted format, and afterward, only changed files (diffs) are sent (also in encrypted format). This allows one to save space and bandwidth.
