I found it! The pref is now obsolete. I will file a bug for the removal of it. http://lxr.mozilla.org/mozilla/search?string=number_of_prefs_copies The pref was introduced by Bug 98476, but was backed out with fixes for Bug 132517 (for problems see Bug 228888), later improved by Bug 250092. As I understand it, there is no need for the backups anymore. So this bug could IMO be resolved.
wontfix per bug 253259.
