P2P backup

September 10th, 2004

A friend and I were talking about a month ago about using distributed file storage in a peer-to-peer overlay exclusively as a backup mechanism. (Really, he had a RAID he didn’t know what to do with; I had laziness that prevented me from making my own backups.) Now RX Cringely seems to have the same idea, but in an effort to monetize it (yes, $4 a month is a windfall for a small start-up company) he’s killed the best part of it. Specifically, with centralized accounting and billing comes a single point of failure. The system is now no longer any better than Napster, structurally, and if the “Baxter” company goes under or gets hit by a tornado, it doesn’t matter if your data is safely scattered across the world. You can no longer access it because you can’t be authenticated by the single central administration. Almost, Cringely—P2P backup has to be completely decentralized.
