Webinar Overview
With the right workload, ZFS Fast Dedup can improve storage efficiency and help offset the rising cost of flash and NVMe storage.
Earlier versions of deduplication required careful evaluation due to memory and performance considerations, and administrators were often advised to avoid enabling ZFS dedup. Fast Dedup introduces a new approach that makes deduplication practical again for many environments.
Allan Jude, Klara Co-founder and Head of Solutions Architecture, and Andrew Fengler, Solutions Architect, are joined by Chris Peredun, Technical Marketing Engineer at TrueNAS, to explain Fast Dedup in the new TrueNAS and how it works with ZFS features like compression, block cloning, and snapshots to increase storage efficiency and reduce storage costs.
We will also examine workloads where deduplication delivers the greatest impact, including virtual machines, VDI, containers, CI/CD artifacts, AI/ML datasets, and backup environments.
What You’ll Learn:
- How Fast Dedup differs from legacy ZFS dedup
- Combining Fast dedup with other ZFS efficiency features to maximize cost savings
- Making NVMe more affordable by storing more data with Fast Dedup
- Workloads with high dedup potential such as VMs, VDI, containers, CI/CD artifacts, AI/ML datasets, and backups

Open source storage supports European data sovereignty by giving organizations full control over their infrastructure, data location, and security policies without vendor lock-in. Transparent, auditable code allows EU organizations to verify how data is handled and maintain compliance with European regulations.
Klara helps enterprises design and deploy ZFS-based storage architectures that ensure operational independence, security, and long-term control.
Vendor lock-in restricts data portability, limits transparency, and can expose organizations to foreign jurisdiction risks. When storage platforms control architecture decisions, organizations lose flexibility over where and how data is stored.
Open source storage removes these constraints by enabling infrastructure portability and independent governance. Our team helps organizations build sovereign-ready storage platforms based on open technologies.
ZFS supports compliance and security with end-to-end data integrity checks, native encryption, controlled snapshots/replication, and predictable operational behavior in production. When correctly designed, it improves resilience and auditability for regulated workloads.
