Duplicati is the only portable backup program, able to send backups in encrypted form to another computer or MS Live SkyDrive using one of several methods (WebDAV, FTP, SFTP/SCP/SSH, Amazon S3, Rackspace CloudFiles, USB disk, Windows network share). Time scheduler e.g. for auto-backups every 3rd Monday on 10 a.m.
German, Danish, English, French, Portugese. Can also be startet from command-line. Support for snapshots via VSS and LVM: Backup of open files.
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.
