Adobe Acrobat Reader, as we usually do with brands and trade names is not translated.
As for backbone, this is the definition provided by the US Federal Standard 1037C: "backbone: 1. The high-traffic-density connectivity portion of any communications network. (188) 2. In packet-switched networks, a primary forward-direction path traced sequentially through two or more major relay or switching stations. Note: In packet-switched networks, a backbone consists primarily of switches and interswitch trunks." It is usually not translated either. Siemens is also a brand; therefore "Backbone da Siemens". I would not use capital letter for "backbone", though... Good luck!

Como já disse o fabcid, o nome próprio do programa não se traduz. No entanto, verifiquei na Internet e os backbones de marcas próprias são usados como indicado acima, com maiúscula e sem "da" (empresa) -- que aliás bate com a forma usada no texto original.
