Backup files and folders with strong AES-256 encryption. Save space with incremental backups and data deduplication. Run backups on any machine through the web-based interface or via the command line interface. Duplicati has a built-in scheduler and auto-updater.
Duplicati is free software and open source. You can use Duplicati for free, even for commercial purposes. Source code is licensed under LGPL. Duplicati runs under Windows, Linux, and MacOS. It requires .NET 4.7 or Mono.
Duplicati uses strong AES-256 encryption to protect your privacy. Duplicati also supports GPG to encrypt your backup.
Built for online
Duplicati was designed for online backups from scratch. It is not only data efficient, but also handles network issues nicely (e.g., interrupted backups can be resumed, and Duplicati tests the content of backups regularly). Broken backups on corrupt storage systems are detected before it’s too late.
Web-based user interface
Duplicati is configured by a web interface that runs in any browser (even mobile) and can be accessed - if you'd like - from anywhere. The web interface enables support for Duplicati on headless machines, like a NAS (network attached storage).
