Move over Box.net, Mozy and Xdrive, Wuala is here ! Those were exactly the words in my mind when I first heard about Wua.la a couple of months back. Back then, it was in a closed beta and I couldn’t try the service. Well, Wua.la is open to the public now and, boy, am I glad !
Wua.la is basically an online storage service. In that sense, it is no different than Box.net, Mozy or Xdrive. What makes it different is the social aspect of it.
Wuala is storage based on p2p technology. Each and every file that you store is broken down into several pieces and each piece is then stored (encrypted, of course) on wuala’s servers and also replicated on some of the other machines connected to the wuala network at any given time. Wuala’s servers keep track of the various bits of the file. The Wuala FAQ explains the technology as:
Wuala is based on a novel technology that we have researched for the most part at ETH Zurich. In addition to servers, Wuala can harness idle resources provided by participating computers. All data is first encrypted and then split into fragments which are redundantly stored on our servers and in the grid network. This allows us to save costs for downloads (bandwidth, electrical power) and thus to provide a better service for free, with a number of advantages that others just can’t offer: unlimited traffic, no file size limits, fast downloads, and so on.
