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 a command-line interface. It has a built-in scheduler and auto-updater.

Duplicati is free software and open source. You can use the app for free even for commercial purposes. The source code is licensed under LGPL. Duplicati runs under Windows, Linux, macOS.

It requires the.NET Framework 4.5 or Mono. It uses strong AES-256 encryption to protect your privacy. You can also use GPG to encrypt your backup.

It 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 the program tests the content of backups regularly. That way broken backups on corrupt storage systems can be detected before it’s too late.

The backup app is configured by a web interface that runs in any browser (even mobile) and can be accessed - if you like - from anywhere. This also allows running the app on headless machines like a NAS (network-attached storage).

Features and Highlights
  • It uses AES-256 encryption (or GNU Privacy Guard) to secure all data before it is uploaded.
  • Duplicati uploads a full backup initially and stores smaller, incremental updates afterward to save bandwidth and storage space.
  • A scheduler keeps backups up-to-date automatically.
  • Encrypted backup files are transferred to targets like FTP, Cloudfiles, WebDAV, SSH (SFTP), Amazon S3, and others.
  • It allows backups of folders, document types like e.g. documents or images, or custom filter rules.
  • The app is available as an application with an easy-to-use user interface and a command-line tool.
  • The program can make proper backups of opened or locked files using the Volume Snapshot Service (VSS) under Windows or the Logical Volume Manager (LVM) under Linux.
