Install Resilio Sync (BTSync) on Ubuntu 18.04, 18.10 Desktop/Server
This tutorial will be showing you how to install Resilio Sync (formerly BitTorrent Sync) on Ubuntu 18.04 and 18.10. Resilio Sync is a free, fast, peer-to-peer file sharing and syncing tool released by Resilio, Inc, available for Linux, FreeBSD, Mac, Windows, Android, iOS, Amazon Kindle Fire and NAS devices.
Unlike Dropbox or NextCloud, Resilio Sync does not require a central server to store files. Instead, you just need to install Resilio Sync on end devices to sync files via the BitTorrent protocol, so you will not be bound by the storage limit of a server.
