Description of problem:
Did create a backup to copy essential system data there, using command
cp -a /sys /run/media/klaus/Bigdisk2/Backup_Fedora19
that did render lots of error messages at shell prompt
and did call Selinux to alarm, preventing /usr/bin/cp from 'associate' accesses on the filesystem pstore.
Think that Selinux preventing 'associate' accesses to filesystem is well done
but error messages to cp -a sys disturbing. 
Want to get this to solution quick.
SELinux is preventing /usr/bin/cp from 'associate' accesses on the filesystem pstore.

*****  Plugin catchall (100. confidence) suggests  ***************************

If sie denken, dass es cp standardmässig erlaubt sein sollte, associate Zugriff auf pstore filesystem zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# grep cp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
