Duplicati for PC — Free Download & Install on Windows 10/11

Do you keep meaning to back up your files, but never find a tool that is both free and easy? This duplicati download for pc guide shows you how to get a free backup program on Windows, how to install it on Windows 10 and Windows 11, and how to set up your first encrypted backup. It protects your files automatically, and it costs nothing to use.

What Is Duplicati?

Duplicati is a free and open-source backup program for Windows, Mac, and Linux. It copies your chosen folders to a local drive, a network share, or cloud storage, and it encrypts the backup, so only you can read it. Backups run on a schedule you set, and you can restore a single file, or a whole folder, from any point in time.

The program uses incremental backups, so after the first full copy, only changed parts are uploaded, which saves time and space. It also compresses data and removes duplicates, so large collections stay manageable. A web-based interface, opened in your browser, guides you through setup in plain language. For home users, that mix of encryption, scheduling, and cloud support makes it one of the strongest free backup choices available.
