Allmydata concept and pricing
Through a very simple user interface, the application gives you the ability of uploading unlimited amount of data to your online account. As you will see from the screenshots throughout this article, you can get up and running within a couple of minutes.
Allmydata has a price tag of $4.99 per month for one computer, with a 30 day free trial. From my experience this is relatively cost effective way of storing backups. During my work hours I regularly use the Amazon S3 service which is a bit cheaper (for the average user amount of data - up to let's say 20-30 gigs of data), but the service needs to be used with third party applications or something your company would develop in-house. The other difference is that shared files through Allmydata don't have any bandwidth limits, so you won't be extra charged for the files you are sharing with your peers.
Files stored in the Allmydata protection mesh are protected in two ways: strong encryption is used with a unique encryption key for each file stored in the network and then each encrypted file is broken up into many small indistinguishable chunks before being sent out for storage. The only way to recover a file is to know which collection of file fragments, out of the millions of similar fragments, need to be collected to reconstruct the encrypted version of your file.
While extremely not likely, but even if an attacker knew which set of files they have to choose from, this would only give them access to the encrypted version of the file. Sounds pretty solid security construction to me.
