DIBS is a backup system that protects your data by giving your files to peers (and in return, you store their files) so that if a catastrophe strikes your area, you can recover data from surviving peers. This solves the problem of mirroring your data by adding more disks to your own computer only ot have a fire, flood, power surge, etc. wiping out your local data center. Note that DIBS is a backup system, *not* a file sharing system like Napster, Gnutella, Kazaa, etc. In fact, DIBS encrypts all data transmissions so that the peers you trade files with can not access your data.
