I have researched this for hours. In Single User Mode, I used:
cp -Rpvn /* /Volumes/MyBackup
My external USB is mounted on
The issue however is that after 24hrs it still has not stopped copying 300GB of data to an external USB drive. I think it is having issues with symbolic links such as the
/Volumes/MacHD volume also having a
/Volumes/MyBackup I am not sure about this however.
How do I copy a Mac volume using
cp -Rpvn /* /Volumes/MyBackup correct?
