Ben Milman from iXsystems has put together a tutorial (How to Set Up FreeNAS with BitTorrent Sync Using a Plugin) showing step-by-step how to install and set up BitTorrent Sync on FreeNAS.
BitTorrent Sync is a free, unlimited, secure file-syncing app which can be easily installed through the BitTorrent Sync plugin for FreeNAS. FreeNAS enables users to build network-attached-storage (NAS) on nearly any hardware platform of their choosing. There is an old tutorial on the BitTorrent blog showing how to configure BitTorrent Sync yourself, but with Josh Ruehlig’s plugin it’s a lot easier now.
If you are using FreeNAS and you need to sync and share large files with anybody via secure, distributed technology, try out the BitTorrent Sync plugin with these install notes.
About FreeNAS: FreeNAS is a FreeBSD-based (nanobsd) and BSD licensed open source Network Attached Storage (NAS) Platform developed by iXsystems, optimised to support file storage and files sharing across Windows, Apple, and UNIX-like systems.
