Duplicati Quarterly Update

Duplicati Quarterly Update

It has now been 3 months since Duplicati Inc was created and it has been a wild ride already. I would like to highlight some of the key achievements we have made in that short timespan.

A new open-source beta release

It is always a big effort to get to a new release. Besides the development effort and coordination, there is always a high level of community involvement, testing a variety of configurations and choices that are not feasible to have in the test setup. During the first quarter we rolled up a year’s worth of community efforts into a new beta release!

New website

The Duplicati website has been based on a free template and has served as the face of Duplicati for several years. But the design looked quite dated, so …

Securing a JSON file with a hidden signature

I promised myself I would never write a file format without a version field, but here we are.

As part of upgrading Duplicati to .NET8, I discovered that the updater manifest file for Duplicati pointed to the “one golden zip file” that was used with .NET4. With .NET8 there is no golden zip file since we have different versions for each operating system, so I had to rework the contents of the file in an incompatible way. This presented a couple of problems:

  • After trying to just enter the new content, I realized the key-length was too short and the file format didn’t support changing the key size.

  • Worse: This was the first time I had to update the file format, and I realized there was no version field.

Migrating from .NET 4 to .NET 8 in 300+ commits

Duplicati is a free and open source backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. I’ve worked on the project for 15 years, along with over 100 contributors, but for various life reasons have had less time to dedicate to the project in the last few years. PRs have been taking longer to get merged, and bigger changes (like upgrading to .NET 8) were dragging.

In March, I announced the formation of Duplicati, Inc, an open core company building on top of the open source project. This development means I can dedicate more time to the project and hire developers to work on improvements and add to the project’s velocity. One of the first major improvements I wanted to make is upgrading the project to .NET 8.

Introducing the new Duplicati website

As part of launching the new company we are hitting many milestones and having a tremendous momentum. Unlike most of the achievements, the launch of our new Duplicati website is a very visual milestone.

The original site was developed using a Github starter template, and refined with the help of contributors to communicate the core values of the project. While the values of the Duplicati Open Source project have not changed, good website design …

Introducing Duplicati, Inc.

It is my pleasure to introduce the newly formed Duplicati company!

I have worked on Duplicati for over 15 years, but it has always been a side project that I spent my spare time on. 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. Naturally, the project has also attracted many voluntary contributors, and it would not be half as good without the massive contributions…
