Duplicati

Duplicati is an open‑source backup tool that encrypts data before it leaves the host and stores the encrypted copies in any major cloud storage service. It operates with a zero‑trust model, ensuring that only the user holds the decryption keys, while the cloud provider merely hosts the ciphertext. The software runs on macOS and is positioned as a stable, production‑ready solution.

The system is designed for managed service providers handling many customers. It offers a centralized console where administrators can define backup policies, schedules, and retention rules once and then distribute them silently to agents installed on client machines. Agents run in the background and are not directly accessible on the host, simplifying deployment and reducing overhead.

Multi‑tenant management lets providers isolate each client within separate sub‑organizations, while a unified view shows real‑time status, alerts, and reports across all machines. Features such as smart retention, automatic deletion of old backups, and remote management support typical MSP workflows without requiring additional tooling.
