Duplicacy redefines cloud backup with innovative lock-free deduplication, enabling multiple devices to share the same storage without direct communication. Emphasizing simplicity, each backup chunk is stored independently, eliminating centralized databases and enhancing security with asymmetric encryption. Discover a backup solution tailored for modern needs.
Duplicacy is a cutting-edge, cross-platform cloud backup tool that harnesses the power of Lock-Free Deduplication. This innovative approach not only enhances backup efficiency but also allows multiple computers to back up to the same cloud storage, maximizing space savings through cross-computer deduplication without requiring direct communication.
Key Features
- Lock-Free Deduplication: Duplicacy’s unique architecture allows independent storage and retrieval of backup chunks using hashing for quick lookups. This methodology negates the need for a centralized chunk database, simplifying implementation, while paving the way for advanced features such as Asymmetric Encryption and Erasure Coding.
- Performance: Designed with speed in mind, Duplicacy has consistently demonstrated superior performance compared to other backup solutions. Comprehensive benchmarking tests have shown it performs significantly better when backing up large datasets, such as the Linux code base.
- Flexible Storage Options: Duplicacy supports a diverse range of storage backends, including popular providers like Dropbox, Amazon S3, Google Cloud Storage, and Microsoft OneDrive, along with local disk backups.
Comprehensive Backup Support
Dedicated to making backups seamless, Duplicacy offers a specialized edition for VMware vSphere (ESXi) called Vertical Backup, enabling effortless backups for virtual machines to local drives or cloud storage.
