Duplicati’s Monitoring Console now delivers AI-generated summary reports on a schedule you define, giving you instant insight into recent backup activity. Customize the focus, language, and delivery channel to get exactly the information your team needs - right when you need it.

Encrypt before you trust. Duplicati’s keep-your-own-keys (BYOK/CMK) design ensures zero-trust backups—only you hold the keys, and no one else can read your data.

Duplicati minimizes backup size through block-level deduplication, storing each unique data block only once across all versions. This design saves storage space, reduces upload time, and keeps encrypted backups efficient even as data changes over time.

We’re excited to announce the next stable version of Duplicati 2.2, bringing a redesigned interface, major performance improvements, and new storage options.

Duplicati’s retention policies make it easy to implement a Grandfather-Father-Son strategy without manual rotation.

SQLite is central to how Duplicati tracks and manages backup data. Unlocking high performance required targeted tuning to handle large datasets and heavy query loads efficiently.

A reworked restore flow significantly improves performance, reducing downtime when recovery counts.

After years in beta, Duplicati has finally moved forward. New resources, community effort, and major feature additions have broken the long-standing release cycle.

New CPU pressure limits make it possible to control Duplicati’s resource usage and reduce system impact.

A major update brings centralized remote backup management to the Duplicati Console. IT teams can now deploy, manage, monitor, and restore machines at scale from a single place.

New secret providers expand Duplicati’s options for securely injecting sensitive data, with broad support available from the start.

A fix to AES header IV generation delivered up to a 1.85× speedup, making encryption effectively free in this case.

A performance bottleneck surfaced during extensive benchmarking. Tracking it down led to a targeted fix that significantly reduced overall runtime.

A live infrastructure migration had to be done with no safe downtime window. By working around DNS and TLS constraints, downtime was reduced from minutes to mere seconds without losing data.

A common security shortcut is put under the microscope. Relying on custom session tokens instead of proven standards like JWT can quietly shift the advantage to attackers.

A request for a security-focused overview revealed a gap in existing documentation. Duplicati’s architecture and design choices are broken down to show how they work together to maximize security.

Three months in, Duplicati Inc. reflects on a fast-moving first quarter. From a major open-source beta release to a refreshed website, the project has already hit several key milestones.

A routine upgrade uncovered a fragile assumption in an old file format. When .NET8 removed the “one golden zip,” the lack of a version field turned a simple change into a breaking problem.

Duplicati is a free and open source backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers.

Open Core Ventures proudly announces the launch of Duplicati Inc.

We’re excited to announce the launch of a our first commercial feature designed to make it easier to setup and manage your Duplicati backups: the Duplicati Portal.

As part of launching the new company we are hitting many milestones and having a tremendous momentum.

The project has grown quite a lot with millions of backups running each month and a vibrant user community that found a home with the introduction of the forum
