Resilio Sync

About

Resilio Sync, a product of the U.S.-based company Resilio Inc., is a robust file synchronization and backup solution that emerged from the BitTorrent Sync Beta, with public discussions dating back to at least 2013 and a notable commercial transition around 2015. Operating on a Free Proprietary license, it utilizes secure, distributed technology based on the P2P BitTorrent protocol to enable automatic file syncing across a broad spectrum of platforms including Mac, Windows, Linux (x86/64, PowerPC, ARM), Android, iPhone, Android Tablet, BSD, Windows Phone, iPad, and Kindle Fire. Its product portfolio encompasses essential features such as file sync, multiple backups with version history, file storage, selective synchronization, decentralized operation, and folder sync. Unique advantages include its capability to modify SD cards on Android for two-way synchronization and a GUI-driven selective sync. While some users laud it as a top-tier tool for NAS backups, it competes in the market with solutions like Syncthing, Gs Richcopy 360, Dropbox, SpiderOak, Box, Sync, and ownCloud. User feedback, though mixed, highlights its speed and peer-to-peer efficiency, but also notes concerns regarding occasional conflicts, timestamp issues, CPU spikes on remote systems, and a perceived shift away from its initial free model. The company facilitates international node access via Amazon AWS server clusters.
