Déjà Dup is a simple backup tool. It hides the complexity of doing backups the Right Way (encrypted, off-site, and regularly) and uses Duplicity as the backend. It features support for local or remote backup locations, including Google Drive.
It securely encrypts and compresses your data. It incrementally backs up, letting you restore from any particular backup. It schedules regular backups, and integrates well into your GNOME desktop.
