Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more).
Duplicati uses AES-256 encryption (or GNU Privacy Guard) to secure all data before it is uploaded.
