BitTorrent Sees Sync Users Share Over 1PB of Data 56

An anonymous reader writes with an update on the rapid adoption of BitTorrent Lab's Sync tool. From the article: "BitTorrent on Monday announced an impressive milestone for its file synchronization tool Sync: users have synced over 1PB of data. The company says over 70 terabytes are synced via the tool every day. BitTorrent first announced its Sync software back in January and released a private alpha. Between then and April 23, when the company release a public alpha, users synced over 200TB worth of data. In other words, over the past 13 days users have synced over 800TB of data. At this rate, the service will pass 10PB before even hitting a stable release."

    I guess that's why it was closed-source only?

      As they are using BitTorrent technology, perhaps the metadata would contain size of data (number of blocks) to be transferred. Considering you can choose to NOT use a tracker, and go DHT (or pre-defined host) only, so probably there are some data transfer that are not accounted in this figure.

      Standard tracker functionality? Yes, you could probably use DHT or similar but old fashioned trackers are simple, reliable and doesn't really give away anything but volume of data transferred.

      So, what are the open source alternatives here for comparison? (doesn't specifically need to be bittorrent) but a good open source multi-platform (win/mac/linux/bsd) sync tool.

      I'm genuinely interested in what others are using/recommending in this area.

        Owncloud is more along the traditional dropbox/cloud storage setup.

        It does require a server system that is accessible for your systems to sync to.

        I'm not sure that there is really anything else in the multi-host peer to peer data sync category yet.

        tahoe-lafs is an opensource, multi-platform, redundant, distributed file system. It looks like it has more features than bittorrent sync, but uploads might be slower.

          Tahoe-Lafs seems to have great potential, reminds me of the OG Wuala, it's a nightmare to get setup at the moment though.

        It lets you do torrents and iMule (and most other things), securely and anonymously.

      Hi, Christian here from BitTorrent. We updated our post to qualify this. Here is the update: "Sync was built for secure sharing. While we have general statistics about the app, we don’t have any access to private information. The client reports back anonymous usage statistics in the same way our other clients do. Sync uses this call to check if there’s a new build available. This call also contains some anonymous statistics that allow us to understand how Sync performs, and how it’s being used; data transferred directly, through relay, size of folders, and number of files synced. This is the only information we collect, and we left it open intentionally – so that people could see the data we’re collecting. That way, it can be easily verified that we don’t have access to any private information. Read more here: http://forum.bittorrent.com/topic/17002-btsync-calling-home/ [bittorrent.com] "
      • It's said in the linked forum thread that collected statistics are anonimized, but there's clearly an ID (id=htRWdGwwER-daEraerE) in the URL called. How is that anonimized, is beyond me.
        • Share all of your anonymous statistics collected by Sync with /b/ and see if they can figure out who you are. Or better yet, Reddit. A string identifying your client is simply to weed out duplicate or fake data, not to tie your sync information to YOU.

          Anonymous data can still be uniquely identified. It is anonymous so long as you can't identify the original person. At work we "anonymize" user data all the time by removing their names/etc and replacing their non-anonymous identifiers with anonymous identifiers.
          • Sooo, what's the great fuss about cookies then? All they contain is some kind of ID, too -- right?

      They are also CPU hogging. I shared few folders just for fun of it, and set automatic start on reboot and everything. Few days later, my laptops are idle for hours, and they are still guzzling power. Fast check, it's btsync, and I presumed idle means no CPU usage, at least no 35%.

      So I killed all four instances I set up for my test. For my needs, one closed source (d***box) solution is more than enough. At least it is not grabbing CPU when presumably idle. What I really need to do, most probably, is to spend

      • by Anonymous Coward

        Wow! If you setup software designed to do its job in the background or when the system is idle - it actually uses cpu and draws power when in operation? How ridiculous, my laptop doesn't draw any power when idle, after a while it starts putting power back into the grid because I use a closed source (d***box) solution.

  • I have no idea how this is even possible, but BT Sync kills my home Mac's network connection. It's so weird. I can ping out from my mac fine, but pinging TO the mac results in 90% packet loss. Needless to say, this makes the network quite useless. Quit the app, no more packet loss. Took me quite a while to track that down!

This process can check if this value is zero, and if it is, it does something child-like. -- Forbes Burkowski, CS 454, University of Washington
