Nathan Peterson ordered to pay restitution of US$5.4m.
A software pirate has been jailed for seven years and three months by a US court.
Nathan Peterson, 27, of Los Angeles, was also ordered to pay US$5.4m and will be stripped of assets including luxury items such as property, cars and a boat.
Peterson amassed the fortune by selling illegally copied products from companies such as Adobe and Microsoft on his iBackups.net website.
The online trader had already pleaded guilty to copyright infringement at a hearing in December 2005 in the District Court in Alexandria, Virginia.
The US Department of Justice described the case as one of the largest it had ever dealt with concerning internet software piracy.
