Any chance to save merging data Google and Facebook contacts? after factory reset of my Motorola Atrix (2.3.7 Android) I can easily restore SMS messages, E-mail, call-history and etc. My problem is that after the reste I have to merge manually contacts imported from Google accounts and the Facebook. 

How can I save the mentioned information?
If you have a HTC phone, with Facebook for HTC Sense, there is an option to backup your merged contacts. It actually use the comment field to put a &lt;HTCData&gt; tag.

(I don't remember exactly the option, so feel free to edit)

Some facebook sync applications such as HaxSync (paid) provide an option to backup contacts links informations. (In the case of HaxSync, it uses HTC tags, so it is compatible with Facebook for HTC Sense and others applications that may also use HTC tags).
