Bittorrent Sync, a file synchronization alternative?

While you may not agree with all decisions that Bittorrent Inc made in the past, I'm referring to integrated ads in uTorrent for instance that look and feel like torrents, you can't deny that the company is pushing out new software at a rapid pace.

The company released Bittorrent Surf for Google Chrome two weeks ago, a program that integrated torrent downloading capabilities into Google's browser.

Today it opened the doors for pre-alpha sign-ups for Bittorrent Sync, a file synchronization service that does not compete with cloud based file synchronization services such as Dropbox, SkyDrive, Google Drive or Cubby, but with solutions that synchronize data between devices owned or used by a particular user of the service.

The blog post (no longer available) fails to reveal important information about the service, and the screenshot that has been posted as part of the announcement is also not that helpful in this regard. The screenshot shows the transfers page of Syncapp where a couple of files are listed, each with its location and up and download speed.

We have to look elsewhere for additional information about the service. Torrentfreak seems to have received early access to Bittorrent Sync. According to the site, Bittorrent Sync offers direct synchronization between devices without cloud storage. While that is great for privacy and device to device synchronization, it also seems to mean that the two devices need to be online for the sync to take place.

Installation seems to be straightforward. Users have to install the sync clients on all systems they want to use it on - currently that means Windows, Linux and OS X as well as NAS devices through a web interface - select a folder to share, generate a private key for authorization and use that key to sync data between devices.

Interested users can sign up for the alpha test. Places seem to be limited which means that not everyone who signs up for the Bittorrent Sync pre-alpha test will receive an invitation to take part in it.

You do need to reveal a couple of information about your current setup, location, email and name to complete the sign up form.

Update: Check out our initial review of Bittorrent Sync, and our review of Bittorrent Sync 2.0, Bittorrent Sync has been renamed to Resilio Sync in the meantime and is no longer owner by Bittorrent Inc.

    I’ve been looking for something like this (realtime syncing files between laptops & desktops w/o the cloud) for awhile now. I signed up for AeroFS but never received the invitation. Looking forward to this useful software!

    Miles long comments at torrent freak is amazing. Martin, have you found out why Ghacks does not get such lengthy comments ?

      I’ve found that most topics on TF turn into a flamewar between MAFIAA and 12 year olds. It can be painful to sift through all the nonsense when looking for valuable info. I wish there was some kind of moderation in place.

      Torrentfreak is the authority site when it comes to “P2P” topics and it has a fairly active crowd hanging around that like to comment.

    Great, this is exactly what I have been looking for. Now I can keep my data synced across both laptops without cloud storage (there is no data that can be used to make money, sorry guys)

    I tried a ton of programs like Cubby, 4Sync etc etc but none gave me what I wanted. Hope this takes off well.
