Sync files securely without the cloud.


BitTorrent Sync allows you to sync unlimited files between your own devices, or share a folder with friends and family to automatically sync anything.

File transfers are encrypted. Your information is never stored on a server in the cloud and your data is protected by private keys.

BitTorrent Sync is specifically designed to handle large files, so feel free to sync original, high quality, uncompressed files.

Had it installed 2 days now seems to do the job. Stable. Easy to use. Had liked to see an option to exclude some files.

This is SO out of date...Now called Resilio Sync, found here:
Version 2.1.3

let me start off by saying that most of the criticism here has long been fixed by BitTorrent. A while back, BT changed their entirely free model to a freemium subscription model, where you had to pay a yearly fee to use premium features. that sucked! not only because i hate subscriptions, but also because it made no sense to have a subscription for something you run on your own hardware. things have changed. the free version has gotten more features and the pro version is a one time purchase. i can only say that it works like a charm. it sits quietly in the background and doesnt need much processing power. it runs on my raspberry pi just as performant as it runs on my workstation. the speeds always max out the possible bandwidth and the load balancing between multiple sources works just as well. i can store files on potentially unsecure servers through encrypted folders and sharing even large folders with friends is easy to set up.

i don't think its the applications fault that YOUR company probably blocks p2p traffic.

True, it's not the application's fault. But with many corporate firewalls blocking p2p traffic, bit-sync would be a lot more useful if it could work through it like Dropbox.

Very happy with this product. Glad I never tried out Pro.

Version 2.1.1

MacUpdate currently shows minimum system requirement for v2.1.1 as OS X 10.5 (Leopard), when in fact it's OS X 10.8 Mountain Lion (per BitTorrent Sync's Help Center).
Version 2.1.1
Agree with a previous commenter who mentioned the bait-and-switch the developer pulled on us. There's simply NO excuse for what the they did to version 2, except that they wanted to rake in more (undeserved) revenue. Version 2 wreaked havoc on my two networked computers. I ended up with partial files everywhere, I presume, because the program can't complete the syncing process. Set up was far too complicated or was buggy because it took many attempts before folders could be synced. Many files that were replaced on one computer were lost because I need up with incomplete versions on the other computer. Version 1 was a near genius product, and I was impressed, so much so I moved to version 2. Bad move! Slow transfers, highly unstabl app, a new, overpriced yearly subscription model. Beware!

A great way to leave the cloud behind. Nice interface, easy to use. Two modes of use- paid/free. It's fast and convenient. All those things are great. BUT Until they can get it to work through hardened corporate firewalls, it's DOA. TeamViewer can do it and other apps can do it. For small offices that can tweak their own firewalls it's great, but for large business it's sadly a no-go. I worked with their support back and forth.

They really screwed this up. At version 1 they had so much potential. And I'm more than willing to pay for the software, even with their weird subscription model, so that's not my concern. They've just managed to completely break the app. There are many bugs and fixes seem to trickle out. Registering devices to your account sometimes results in a hang or crash. Also, canceling my subscription took 8 separate responses to a help desk ticket before I was finally able to get in and stop the recurring charge. I love the concept of being able to host and manage my own data without having to rely on someone else's infrastructure, but the execution in v2 is just poor.

Version 1 was great. Very stable and easy to use. Version 2 crashes on a simple sync. It's hard to manage shared folders. Folders are popping up on computers i don't want to. Rights are a mess. Things that where syncing for a year without a problem are read only after a upgrade. I don't mind to pay for good software. (like version 1) This is just not working.

I was using BTSync for several months and even have purchased the PRO version of it. Until I found it isn't possible to have a shared folder (1 common folder for more than 1 user account) to sync. The BTSync team told me this is how the app is designed - great, I moved on with owncloud. Maybe I have to explain the situation more clearly: my wife and I both use a MBP and there are files that are used by both of us. Now, you can double the needed space as each user has to have its own copy of each file. A lot of wasted space.
