Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud-storage services and remote-file servers. It works with Linux, Mac, and Windows.

Duplicati has built-in AES-256 encryption and backups can be signed using GNU Privacy Guard. A built-in scheduler ensures that backups are always up-to-date. The Duplicati project was inspired by duplicity, and while similar, they are not compatible.
