It is called BitTorrent. Generate the backup file as described in the parent article, give it a saucy name involving a (female) celebrity and let it out into the wild. As disk space is effectively free and people tend to hoard files, I suspect you'd have no problems recovering your file a year or two down the line. (I tried this way back when using WinMX (anyone remember THAT?) to see whether it would work. It did.) We dubbed it 'hardcore backups.'
