I had always been reluctant to store or backup some of my personals data in the cloud storage (privacy concern) until i discovered Duplicati !Duplicati.com wrote: 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.
Now, in addition to my local backups, i store some of them remotely and securely !
Just configure what you want to backup and Duplicati do the rest.
An example of remote backup (full + incremental) . The local source folder (~ 300 MB) is uploaded in several volumes (here, configured at 10 MB max each):
An example of the main GUI:
Website : http://www.duplicati.com/
License : LGPL
Dependencies : .NET 2.0+
Portable : Yes. Launch Duplicati.exe with the command-line --portable-mode (cf. Other protection measures)
Stealth : Yes.
Valuable informations are also available in the wiki (e.g: Some Background Information on how it started).
One cons. : sometimes the "Duplicati Wizard" can be non-user-friendly for modifying or updating settings of existing backups. But, according to the roadmap, a new GUI is planned.
