Duplicati is a free, open-source backup software designed for online backups, offering encrypted, incremental, and compressed backups to local storage, cloud services like Amazon S3 and Google Drive, and remote file servers via protocols such as FTP, SSH, and WebDAV.

Key features include AES-256 encryption, data deduplication, automatic backups with a built-in scheduler, and the ability to resume interrupted backups. Duplicati provides both web-based and command line interfaces for easy access from any browser or remote location, making it ideal for users seeking reliable and efficient backup solutions.
