Install Bittorrent Sync on Debian / Ubuntu
BitTorrent Sync is a new piece of software by BitTorrent Inc. - the original creator of the BitTorrent protocol. While most might be familiar with BitTorrent, only a few know of BitTorrent Sync. Normal .torrent files are static and once created they can't be altered anymore. BitTorrent Sync however allows updates to the data and syncs them to the peers. BitTorrent Sync is also available cross-plattform (Linux, Android, Windows, Mac OSX, iOS) and it has two distinctive operation modes. You can have a many-to-many synchronization meaning that every node can alter the content and have it synced to the other devices. Or you can have a one-to-many synchronization meaning that only the Master Node can alter data and this is then synced to all other nodes. Especially the one-to-many synchronization is of interested if you want to create backups and store them at multiple sites - using the power of BitTorrent swarms (meaning each nodes starts providing updates to other nodes as soon as they are received).
