TrueNAS + Syncthing: Sync Two Active-Active Datasets Step by Step

Published 04/06/2026

Description

Learn how to set up TrueNAS and Syncthing for active-active dataset synchronization step by step. In this video, I show how to deploy Syncthing in Docker on TrueNAS, secure the web UI, connect two Syncthing nodes, map datasets correctly, and configure bidirectional file replication for a practical homelab or small LAN setup. 0:00 - Introduction 0:12 - Description 2:41 - Install 5:06 - Initial Startup 5:34 - Web UI Security 7:20 - Connecting Syncthings 11:11 - Dataset Configuration 13:09 - Syncthing Folders 15:47 - Replication 17:31 - Advanced Settings 0:41 - Code 24:24 - Conclusion You’ll also see how TrueNAS dataset mapping affects Syncthing behavior inside the container, how synchronized folders should be configured, and what happens during real-world replication tests. I cover conflict files, explain why they happen in an active-active sync setup, and walk through advanced Syncthing settings to improve reliability, control, and consistency. If you want a complete walkthrough for building a two-way file sync solution on TrueNAS using Syncthing, this video covers installation, configuration, testing, replication behavior, and advanced tuning.
