E189: Why Your Backup Platform Should Be Open Source with Plakar

E189: Why Your Backup Platform Should Be Open Source with Plakar

Author: Robby (MTF); Tim (Essence VC) January 15, 2026 Duration: 39:54

In our latest episode, co-hosts Robby and Tim talk with Julien Mangeard, Co-Founder of open source backup platform Plakar. Plakar's open source, also called plakar, has 1.5K stars on GitHub and provides a backup solution powered by open source, immutable data store Kloset.

The podcast discusses why data backup remains a critical but unsolved problem, especially as the number of data sources has exploded across SaaS applications, cloud databases, and on-prem systems. For CISOs and CTOs, this complexity makes it increasingly difficult to ensure everything is done “the right way.” The core argument is that the only truly safe approach is maintaining an independent, secure copy of your data - without vendor lock-in and with guaranteed long-term access, sometimes for decades. End-to-end encryption, immutable storage, and compatibility with different storage backends are emphasized as essential foundations rather than optional features.

The conversation contrasts hype-driven cloud-only backup companies like Eon with Plakar’s back-to-basics approach: an open source, resilience-focused system designed to handle large and diverse datasets securely. Built around an immutable storage engine (Kloset), Plakar aims to let individuals or small teams manage their own backups while also supporting collaboration at scale. The founder’s motivation is rooted in personal experience- having previously lost critical data as a CTO - which reinforced the need for security, openness, and community involvement to continuously add and validate new data sources in a rapidly evolving data landscape.


Building a company around open source software is a unique and often misunderstood path, full of specific challenges and rare opportunities. The Open Source Startup Podcast digs into that journey directly with the people who have navigated it, moving beyond theory to the practical realities shared in conversation. Hosts Robby and Tim bring their distinct perspectives from MTF and Essence VC to these discussions, creating a space where founders speak candidly. You’ll hear from the architects behind names like HashiCorp, MongoDB, and Vercel, as well as leaders from Chronosphere, DBT, and mobile.dev, as they unpack their experiences. This podcast focuses on the pivotal decisions around community building, monetization strategies, and maintaining project ethos under the pressures of scaling a business. Each episode serves as a detailed case study, revealing how these companies turned publicly available code into sustainable, impactful enterprises. The dialogue naturally explores the tensions between open collaboration and commercial needs, offering a real-world blueprint that is both instructive and nuanced. For anyone curious about the intersection of community-driven development and venture-scale growth, this series provides an essential and unfiltered resource.
