failed to enable ownership

[conduit]

Hi
attempting to copy MBP HD to external drive. usually a flawless process has kicked up a red error that says "Failed to enable ownership of Macintosh HD." I will include the log below. any ideas would be greatly appreciated as i feel a little exposed having not backed up since before the holidays.

thanks
