What is Duplicacy?
Duplicacy represents a modern approach to data backup through its innovative lock-free deduplication technology. This system operates by utilizing basic file system APIs to manage deduplicated data chunks without requiring locks, while implementing a two-step fossil collection algorithm that enables deletion of old backups without centralized chunk databases.
The tool provides extensive cloud storage compatibility alongside support for local disks and SFTP servers. Users benefit from both a web-based graphical interface for intuitive backup management and a powerful command-line interface for advanced automation. The solution offers source code accessibility for transparency and customization, with commercial licensing available for organizational deployment.
