I’ve been toying around with a wonderful free utility from BitTorrent Labs called BTSync. You can find it here: http://www.bittorrent.com/sync.

What really drew my attention was the lack of centralized service that stands at the core of BitTorrent technology. It’s distributed, without any company or cloud provider dwelling in the background. All the hardware is owned by you, the “secret” code you use to share that identifies your sync experience also forms the encryption key so that the data that is flowing across the network is secure from prying eyes. Because you own all the hardware and encryption covers the data exchange, you can store whatever you like in your BTSync’ed folder and not have to worry about anyone else peeping over your shoulder or removing material from your storage without your knowledge or permission.

This free system has clients for workstations and mobile devices, so it really can be a drop-in replacement for services like Box, Dropbox, Google Drive, and SkyDrive. You can share the secret with anyone you like and anything you place on the folder set up with BTSync will synchronize across all the connected devices. You can also send “Read Only” secrets to sync your folders to people who you want to have your files but don’t want them deleting or changing your files and since this uses BitTorrent technology you won’t have to pay hosting fees and the more people share the data, the faster the system sends updates and changes and new data to all the subscribers.

I’ve created a Work folder, a Sync folder and have them set up on my work machine, my work laptop, my Mac Mini at home, and my iPhone and iPad. Since I own all the hardware, the maximum storage that I can store on this system is only limited by the smallest storage unit amongst all the shared machines. The folder lives on a 1TB USB HD at home, at work I have hundreds of GB’s available and the same as on the laptop. The storage in Mobile isn’t the same as a full workstation as the BTSync app doesn’t actually download data to store on the mobile devices directly but rather downloads a file list making it possible for you to pick and choose what you need on mobile when you need it. If you need security in the storage components you could leverage Encrypted Disk Images in Mac systems and TrueCrypt Encrypted Volumes on Windows machines. For Linux clients, you could likely use loop filesystems set with EncFS or something like that.

The applications for BTSync are amazing. Freed from middlemen companies I can store anything I like without having to worry about some company evaluating what I’m storing or even being able to respond to warrants to reveal what I’m storing on the service. Something like this could be a great benefit to companies that need to share files without having to worry about “buying into the Cloud” since everything is free. You can run a BTSync on a server, host a folder and share the secret out to all your employees and have a very handy share drive and even if your central server fails, copies of your data are stored on all the connected workstations so to recover the data all you would need to do is download the small BTSync client again, re-establish the shared secret code, identify a folder and watch as all your connected clients swarm and return all your data back to the “central depot” server.

Another wonderful option is to host a family shared folder, where you can store anything you like, securely and backed up amongst all the connected workstations. Alternatively, if you were an aspiring artist you could place a folder with all your work and establish a read-only secret and publish it on your social networks. Not only would all your fans be able to have your work, but you’d also be able to cleverly transform them into a swarm of willing backup sources for your work. If an artist has their secret code and a copy of BTSync client and they lose their primary system and all their data, they can just get a new system, re-establish the client and secret and smile as all their work comes back home as it was stored on all your fans computers. That’s amazing to me!

Getting started using this utility is a snap. Download the client and install it on your system. Then on whatever storage medium you like create a new folder. In the BTSync application itself you can create a new shared folder with a single click, there is a “Generate” button which creates the shared secret for you, you can then determine if you want it to be full-sync or read-only sync and then point the app to the folder you want to share, then minimize the app and you’re all set. Send the shared secret code to anyone you want to share with and your data will immediately be sent to their systems according to your preferences.

BTSync is the best of all worlds. You have a secure cloud infrastructure without anyone in your way, judging you or risking any intrusions from companies or governments.
