Duplicati2.4.0.0

Duplicati creates encrypted backups of files and data, stores them in cloud or local destinations, and restores them when needed. It uses a zero-trust design and applies AES-256 encryption on the machine before any data travels across the network, while immutable storage helps keep backup copies available.

The program works with major cloud and storage services through S3, WebDAV, SFTP, and local hardware, including AWS S3, Azure Blob Storage, Wasabi Hot Storage, and Backblaze B2. It can protect local servers, NAS devices, desktops, and laptops, and save Microsoft 365, Google Workspace, or S3-bucket data to an on-premises SAN or private S3 cluster. SFTP or SMB connections can route local-machine backups to network-attached storage while keeping traffic on the internal network.

For organizations managing many machines, a central console shows real-time backup status and activity and lets administrators set schedules, retention rules, and destinations once, then push them to multiple clients. Multi-site controls allow global administrators to delegate local management to regional IT staff, keep departments in separate sub-organizations, and invite customers into their own spaces. Background agents run quietly and remain inaccessible on the host, while changed-block transfers reduce WAN traffic and cloud egress costs and can be scheduled outside peak hours.

It suits individuals, small offices, IT teams, and service providers protecting laptops, servers, NAS systems, or cloud workloads while choosing their own storage provider; Duplicati adds no storage fees or bandwidth limits and supports unlimited clients and endpoints under one subscription. Duplicati is freeware and open-source in the Backup & Recovery category; the current 2.4.0.0 release targets macOS 12 Monterey and later on Apple Silicon arm64.
