Duplicati is an open source free backup program that creates backups with the ability to store them securely encrypted, incremental and compressed on cloud storage services and remote file servers. At the moment it has the ability to work with Amazon S3, Windows SkyDrive, Google Drive, Tahoe LAFS, Rackspace Cloud or it can use your own SSH, WebDAV, SFTP or FTP file server.

One big advantage of Duplicati is that it uses standard UNIX components such as rdiff, zip, AESCrypt and GnuPG to create the backups. This will allow you to recover the files even if Duplicati is not available. A built-in scheduler makes sure that backups are always up-to-date. Duplicati is licensed under LGPL and available for Windows and Linux.
