Overview
Duplicati is a free, open-source backup application that creates encrypted, incremental backups of files and folders and stores them on cloud, network, or local destinations, with all encryption happening client-side before data leaves the source machine.
In active development since 2008, Duplicati was a purely community-maintained project until 2024, when Duplicati, Inc. was founded by CTO Kenneth Skovhede with backing from Open Core Ventures to commercialize enterprise-grade features on top of the free core.
Key Features
Duplicati encrypts data with AES-256 locally before uploading incremental, block-level deduplicated backups to a destination of the user's choice, including Amazon S3, Azure Blob Storage, Backblaze B2, Wasabi, Google Drive, OneDrive, SFTP, and WebDAV.
A responsive, web-based interface lets users schedule, monitor, and restore backups from a desktop, server, NAS, or mobile browser, and the software runs cross-platform on Windows, macOS, and Linux.
Pricing
The Free plan monitors up to two machines and the last 200 backups at no cost. The Pro plan costs roughly $2 to $2.50 per machine per month for up to 100 machines with alerts, AI-assisted analysis, and 100 GB of storage per machine.
The Enterprise plan starts at $3 per machine per month with a 10-machine minimum on an annual contract, adding organization management, SSO with MFA, and agent-based deployment, plus optional add-ons for Microsoft 365 and Google Workspace backup.
Key Features
Client-side AES-256 encryption — All data is encrypted locally before it ever reaches the network or the storage destination.
Incremental, block-level deduplication — Only changed data blocks are backed up after the initial run, minimizing storage growth and transfer time.
Broad storage backend support — Backs up to Amazon S3, Azure Blob Storage, Backblaze B2, Wasabi, Google Drive, OneDrive, SFTP, WebDAV, and local paths.
Web-based user interface — A responsive browser UI supports headless server and NAS use as well as desktop and mobile management.
Scheduled automated backups — Backup jobs run on a configurable schedule without manual intervention.
Cross-platform support — Runs natively on Windows, macOS, and Linux.
Central fleet monitoring dashboard — Pro and Enterprise tiers add missed-backup alerts and remote management across many machines.
Microsoft 365 and Google Workspace backup — Paid add-ons back up mailbox, OneDrive, SharePoint, Gmail, Drive, Contacts, and Calendar data.
