ZFS deduplication has traditionally come with a pretty strong warning: know your workload, or don’t enable it at all.
With Fast Dedup in newer TrueNAS releases, that guidance may be shifting.
We’re hosting a webinar that takes a closer look at what’s changed and where it actually makes sense to use:
- How Fast Dedup differs from legacy ZFS dedup
- Interactions with compression, block cloning (BRT), and snapshots
- Real-world workloads with meaningful dedup potential (VMs, VDI, CI/CD, backups, etc.)
- Whether this actually changes the RAM/performance trade-offs that made dedup risky before

Curious to hear from people on PracticalZFS—are you starting to reconsider dedup with these newer approaches, or still avoiding this feature?
