No idea about the detection (I don't expect an easy way), but the answer to the second part is to copy the files after disabling block cloning. As this is system stuff, I would expect it is not much data, and you could copy everything and then move back to the original place. I would also assume original log files are not affected, and only files which were copied (installworld or installkernel or backup files or manual copies or port install (not sure about pkg install)) are possible targets.
