BitTorrent Sees Sync Users Share Over 1PB of Data

Posted by Unknown on from the zero-point-one-internet-archives dept.

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."

      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/ "

      From reading the descriptions on the sync site... no. Anyone with the key can access the files. This provides some security, but it is pretty brittle. As long as everyone using it understands the level of security that should be applied to that key. i.e. anyone who steals the key can access the files. So, for example, never send the key over email.

      This seems like a reasonable solution for either just syncing personal files, where one individual has control of the key(s). Or syncing among a small technical group where everyone understands the relevance of the security of the key(s). Or syncing low-risk files among a less formal group.
