Duplicati is a free backup software designed for secure, encrypted backups of files and folders. It runs on Windows, macOS, and Linux, and is suitable for both personal and professional use. The program allows users to back up their data to cloud services, remote servers, or local drives with ease.

Duplicati supports standard protocols like FTP, WebDAV, and SSH, as well as popular cloud storage providers such as Google Drive, Dropbox, and OneDrive. Backups are compressed and encrypted using strong AES-256 encryption, helping protect sensitive information during storage and transmission.

Duplicati works through a web-based interface that runs in the background. Users can schedule backups, define rules for file selection, and set limits on retention. Its user-friendly dashboard makes it easy to monitor progress and restore files when needed.

Designed for reliability and privacy, Duplicati uses incremental backups and deduplication to reduce storage space and network usage. With open-source development and community support, the software provides a transparent and adaptable solution for backing up important data.
