Duplicati is an open-source backup application designed to securely store encrypted backups on cloud storage services and remote file servers. It provides a flexible way to protect files by combining compression, incremental backups, encryption, and support for many online storage platforms.
The software is built for users who want more control over their backup process than traditional backup tools usually provide. Duplicati can connect to various storage destinations, including cloud services and standard network protocols such as FTP, SSH, and WebDAV. It supports popular platforms such as Google Drive, Amazon S3, Microsoft OneDrive, Backblaze B2, and other compatible services.
Security is one of Duplicati’s main focuses. The application includes AES-256 encryption to protect backup data and also supports GNU Privacy Guard for additional encryption options. This allows users to store backups online while maintaining control over their private files.
Duplicati uses incremental backups to reduce storage usage by saving only changes made since the previous backup. It also includes compression and data deduplication features to help optimize backup size and transfer efficiency. With its built-in scheduler, automated updates, web-based management interface, and support for multiple operating systems, Duplicati provides a powerful backup solution for personal users, professionals, and organizations that need reliable data protection.
