- November 2013 Update:
Brian Tapitch of Zynga has replaced Bitcasa CEO Tony Gauda.
After just 2 months, he jolted followers with a 2000% price inc-
rease. Check out our November 2013 update to this article.
Bitcasa has just emerged from “skunkworks” mode. The cloud storage startup made waves in 2011 as finalist at TechCrunch Disrupt and runner up at Startup Battlefield. After burning through an initial $2 million, they landed an additional $7 million in June 2012. While there were few updates during 2012, some analysts noted that they filed for 20 patents—a few are really slick! Now, during Feb 2013, they have unveiled a cloud service with an edge over all others (SkyDrive, iDrive, Dropbox, Sugarsync, etc). In my opinion, only Symform and SpaceMonkey come close to the model that I described 3 years ago (search for ‘Ellery’ and ‘RDDC’).
Bitcasa gives every user folder sync, a timeline for version recovery, and cloud storage without limits. And, I really mean limitless! By the end of next month, I may be using petabytes, as in millions of gigabytes! The space available to me shows exabytes are still available. That’s more than all the grains of sand on the world’s beaches and all the stars in the heavens. How much does this cost? Just $99 a year, or $49 if you sign up early this month.

I can’t guarantee that Bitcasa will be around next year. After all, most startups fail. But in this case, I crafted a substantially identical network architecture years ago. I understand the business model. Even with a high fraction of data hogs, the venture can profitably service users for the long haul. If an understanding of the secret sauce isn’t sufficient to assuage hesitation, this interview with CEO Tony Gauda will floor you. He combines the technical and marketing genius of Steve Jobs with the showmanship of Siegfried and Roy, and the smile of Barak Obama

Seems like a virtual drive. I need automatic backup of
my important data. I use Carbonite for this right now.
The folder-sync defaults to all drives in their entirety—even external drives and network attached storage! If you accept the default, it always backs up everything. But more importantly, Bitcasa reverses the model. As connectivity becomes more ubiquitous and speedy, they want you to use the cloud as your primary active storage. Eventually, it will even host your live EXE files (your apps) and your “bootable” OS. The synchronized copy on your PC will be the backup – as well as the one that is used when you cannot connect.
I proposed the fundamental principles used in Bitcasa architecture in this Blog, and 3 years ago in other articles. I called it a “Reverse Distributed Data Cloud” (RDDC). My spec adds distributed, P2P storage to the model. This reduces cost, creates redundancy, and makes a far more robust system. Not only does it get rid of the data center completely. With my model, it is unnecessary for the service provider to perform any backups. In effect, the live cloud is a RAID 10,000 constellation.
One architectural trade-off is the desire for massive de-duplication –vs– the compelling need for end-to-end encryption, in which only the individual users have the keys. These two features are incompatible. DropBox and Bitcasa claim that files are encrypted at the sender and that private keys are never given to the service. While technically true, that claim covers up a nasty little detail. They use a method called Convergent Encryption in which encryption keys are derived from a character string within the encrypted file. Although the service cannot decrypt a unique file (for example, your income taxes), they could compare a hash of your file to one provided by a government or alleged rights owner, thus proving that you have stored a copy of contested media. They could block access to movies and music that you have stored or even block your original upload. The good news is that with a full RDDC implementation, the need for de-duplication is greatly reduced or even eliminated. Therefore, a properly implemented RDDC can truly empower its uses with strong, end-to-end encryption.
I’ll report more about Bitcasa after a few months of use. For now, I feel ratified to see my dream taking shape at several American ventures. If you find this field as fascinating as me, check out Symform, SpaceMonkey and Digital Lifeboat. That last venture is floundering, and may be bankrupt by the time you read this. But they have some very compelling technology for p2p, distributed storage.
